Tripp Lite Isobar ISOBLOK2-0 Heavy Duty Outlet Extender, Wall Power Strip Surge Protector, 2 Outlets, Direct Plug-in, White, Metal Power Strip, Industrial Garage Work Shop Bench

Great product! It is inexpensive and works well. I use three Tripp-Lite Isobars to protect my three peered subwoofers.

I install home theater systems for a living. I purchase these units for cramped locations (such as custom TV cabinets or behind wall mounted TVs). These surge protectors are perfect for my needs: 1) Compact. A regular surge protector bar will not fit in any of my customers custom TV cabinets. I require a surge protector small enough to fit over an outlet without being bigger then the outlet itself. For example, these fit in the right side of a 2 gang, Combination Cable TV & Power outlet; without blocking the TV cable plug. 2) Quality. I only use high quality products in customer installations. These units exude quality both in specs and looks. 3) Protection. These surge protectors are small, but they have a surge suppression rating of 1410 Joules. That's pretty incredible for such a small unit; higher then most in-home surge protector bars. This means whatever is plugged into these (in my case LED TV's) will have a better chance of surviving then a lower rated surge bar. It's backed by a 10,000 Dollar "Ultimate Lifetime Insurance and Lifetime Product Warranty." 4) Noise Filtration. This is a feature found only higher quality surge protectors. This feature prevents appliances (blenders, refrigerators, fans) from degrading your TV picture and sound quality when in use. It also helps prevent lock-ups and data errors on PCs and other high end components. This is a MUST. 4) Heavy Duty. Yeah, these aren't breaking, ever. Every surface is solid metal, painted black. They weigh about 1 pound, which is lighter then I thought they would be. 5) Doesn't fall out of outlet. Despite their relative bulk and heavier weight, I thought these would just fall out with the slightest tug of an electrical cord. Not so. They fit solid into an outlet, and it's not going to fall out. It has a rubber boot on the back of the unit for extra leverage against the wall. 6) Easy. They plug in and work. No buttons. Plug in, your done. I am extremely satisfied with this purchase and the price I paid. If you are looking for a small, affordable, QUALITY surge protector, I HIGHLY recommend these. I'm a very pleased, very impressed, and very satisfied customer. Thanks Tripp Lite. We appreciate quality products at fair prices. Please keep it up!

Well built and a great addition to protecting delicate electrical items I own. So far works well through any storm we’ve had here.

Tripp Lite makes very good surge & filtering products and I've been using them for many years. Their "Isobar" series really hits the sweet spot because you can isolate plugged in devices from each other. Here is a tip: For some odd marketing reason, the manufacturers and sellers of surge protection device focus on selling you joules, and imply that higher joules means more protection for your plugged in device. This is only part of the story. Yes, high joules might get you longer life for the surge protector itself (if you live in an area with very high surge events). Equally important is the "let-through" voltage, also known as "clamping voltage." This number should be low, so at least 330V (also called Class 1), which is good. There are surge protectors available that get down to 180V let-though, but these are harder to find. If you have lots of electronics in your home, start with a "whole house" protector installed in the circuit breaker box. Then layer by protecting individual things like computers and TVs with power strip style protectors.

Solid unit and performs as advertised. My issue is that the unit design causes issues with limited clearance between the protector and the appliances, as was my case. My washer and dryer is in a basement bathroom which has limited floor space. If the outlet is behind the units (wasn't until pedestals were installed), then the 4" depth of the surge protector, combined with the length of the washer plug of another 4" resulted in moving the washer too far away from the wall. I got around this by plugging the surge protector into a spare appliance extension cord I had and then the extension cord into the wall outlet. A simple design change by Triplite would eliminate this issue by putting the surge protector outlets on the side of the unit while keeping the status lights on the front. What should have been a 5 minute job to install turned into a half hour and a lot of reaching over and behind the units while on a 4 foot step letter.

I use this heavy-duty surge protector with my computerized longarm quilting machine.

Product: Tripp Lite ISOBLOK2-0 2-Outlet Direct Plug-In Surge Protector The Good News First Let me be clear: the ISOBLOK2-0 is genuinely excellent surge protection hardware. After spending considerable time researching surge protector specifications across every major brand, here's what makes this unit stand out: Protection Specs: * 1,410 Joules energy absorption * 140V RMS / 330V VPR clamping voltage across ALL THREE protection modes (L-N, L-G, N-G) * 48kA surge current rating * <1 nanosecond response time * UL 1449 4th Edition Listed * All-metal construction (not cheap plastic) * Diagnostic LEDs for protection status, power, and line fault * $10,000 connected equipment insurance These aren't just marketing numbers - they actually matter. The clamping voltage (VPR) is the MOST important specification, more important than joules. It determines the maximum voltage that reaches your equipment during a surge. Lower is better, and 330V is the gold standard per UL 1449. Why I Bought Five of These I needed compact, high-quality surge protection for ceiling-mounted applications: garage door openers, a ceiling-mounted projector, and battery charging stations where space is tight. The product images on Amazon clearly show the ISOBLOK2-0 with a mounting bracket attached - a small metal bracket with screw holes that would allow wall or ceiling mounting independent of the outlet. Perfect, I thought. Premium protection with mounting versatility. I ordered five units. The Bad News: Mounting Brackets No Longer Exist When the units arrived, there were no mounting brackets. None. After digging through other Amazon reviews, I discovered that Tripp Lite has discontinued the mounting brackets entirely - they're no longer manufactured or available. Yet the product images on Amazon (and Tripp Lite's own website) STILL SHOW the bracket attached to the unit. As of January 2026, these misleading images remain live. This matters more than you might think. Without the bracket, this "direct plug-in" surge protector is really only practical for standard wall outlets where gravity isn't working directly against the connection. Ceiling outlets - like for garage door openers or projectors - are fighting gravity constantly, and the weight of the unit plus connected cables will inevitably work it loose. Look at the photo I attached to this review. That's my actual installation - the ISOBLOK2-0 plugged into a wall outlet with a smart plug and my Anker SOLIX battery charger connected. Notice the gap already forming where the unit is pulling away from the outlet plate. This is on a standard wall outlet, not even a ceiling mount. Without some kind of mounting solution, this thing is eventually going to work itself loose and fall. That's not acceptable for a premium surge protector. The product images show a capability that no longer exists. That's false advertising, plain and simple. I Researched Alternatives - There Really Aren't Any Here's where it gets truly frustrating. I spent hours researching every major surge protector brand trying to find an alternative with equivalent specs AND mounting capability. The uncomfortable truth? Tripp Lite's ISOBAR line is the only consumer brand that consistently delivers 330V clamping across ALL THREE protection modes (L-N, L-G, AND N-G). I checked Leviton (600-700V clamping - way too high), CyberPower (400V+ - fails the VPR requirement), Monoprice (330V on L-N only, 400V on the other modes), Panamax (close, but rack-mount form factors only for comparable specs). Everyone else cuts corners on L-G and N-G protection because most consumers don't know to check those specs. So if you want proper surge protection with 330V clamping across all modes, Tripp Lite is your only real option. Which makes it all the more frustrating that I now need to engineer a mounting solution that Tripp Lite used to provide but quietly discontinued. DIY Mounting Solutions (Since Tripp Lite Won't Help You) Since I'm committed to these units and still need to mount them properly, here are the solutions I've come up with. I'm sharing these for others stuck in the same frustrating situation. I'm a former aircraft electrical mechanic turned IT/Network Engineer, so I'm comfortable fabricating solutions - but I shouldn't HAVE to. Option 1: Stainless Steel Hose Clamp + L-Bracket (~$5) Use a hose clamp sized to fit the ISOBLOK2-0 body (~2.5" width) Attach clamp to a small L-bracket or angle bracket Screw bracket into ceiling joist or use toggle bolt The all-metal ISOBAR construction handles clamping pressure fine Pro: Secure, adjustable, removable, hardware store parts Option 2: Rubber-Lined P-Clamp / Cushioned Loop Clamp (~$3) Aircraft-style rubber-lined P-clamps work great here Size for ~1.5-2" diameter to grip the body Mount to ceiling framing or strut channel Pro: Clean professional look, vibration-isolated, won't mar the finish Option 3: Industrial Velcro + Backing Plate (~$8) Cut a small aluminum or steel plate as backing Apply 3M Dual Lock or industrial-strength Velcro Mount plate to ceiling/wall, Velcro to surge protector back Pro: Easy removal for inspection, no permanent modification Option 4: 3D Printed Bracket (~$2 in filament) Design a snap-fit cradle matching the unit dimensions Include screw mounting holes Print in PETG or ABS for heat resistance Pro: Can replicate the original bracket design exactly Option 5: Unistrut Mini Section (~$10) Short piece of 1-5/8" strut mounted to ceiling Use strut clamps or spring nuts to secure the unit Pro: Professional electrical installation appearance, infinitely adjustable None of these are hard if you're handy. But that's not the point. What Tripp Lite (Eaton) Should Do, immediately! 1. Update the product images immediately to remove the discontinued mounting bracket 2. Update the product description to clearly state "direct plug-in only, no mounting hardware included" 3. Offer the mounting bracket as a separate accessory for customers who need it 4. Or better yet: bring back the bracket - it's a stamped piece of metal, not rocket science ⭐⭐⭐ Bottom Line The ISOBLOK2-0 delivers genuinely excellent surge protection - 1,410 joules, 140V RMS (330V) clamping voltage across all three protection modes, all-metal construction, UL 1449 4th Edition certified. After extensive research, Tripp Lite's ISOBAR line is literally the only consumer brand that consistently delivers 330V clamping across L-N, L-G, AND N-G modes. The competition all cut corners somewhere. So if you want proper protection, you're buying Tripp Lite whether you like it or not. The 3-star rating isn't about the protection - that's flawless. It's about the fact that I now have to spend additional time and money fabricating my own mounting solution for what's supposed to be a premium product. The images clearly show a mounting bracket. The bracket doesn't exist anymore. I bought five of these units expecting a feature that Tripp Lite quietly discontinued without updating their marketing. For standard wall outlets: This is a 5-star product. Buy with confidence. For ceiling mounts or anywhere you need to secure it: You're looking at a DIY project. The protection is still best-in-class, but budget an extra trip to the hardware store and some of your weekend. You shouldn't have to, but here we are. Tripp Lite (Eaton): Update your images. Or bring back the bracket. Your customers deserve accurate product information.

My initial look of this ISOBARs, thought was an over-priced antique, it turns out, this is exactly what i needed. My NetGear PLP2000 Network AC line adapter, this is my primary source of wired-internet to for my daily work @ home environment with descent speed and low ping, our internet modem is located in far end of a fairly big square ft home property, WiFi is not a solution for me, so i have two of these PLP2000 at both far end points. Recently i have purchased an "LG Dual-Inverter window AC". Even though the LG AC system is 25% lower energy consumption than Energy Star compliant, but when it kicks in, it still effects the PLP2000 in any of the outlets in my room and causing internet bandwidth to drop real low! After installing this to my AC system, this power line ISOBAR2 fixes that room's power outlets instantly and any of the adjacent wall where my network adapter is plugged in and thus restored my network speed back optimal while AC is actively on for the brief moment. - all lights are GREEN! Looking forward to get a few more knowing that it fixes my room, im going to assume both end points where there are heavy power draws it is ideal to add one of these things. including microwaves and such. hopefully will last for years to come, i know Triplite has been around for their quality reputations.
