TetherBlock Camera Cable Port Protection for Cable Management

used in on the Nikon d850 with the hand grip works the best i think today they issued a better version of this product

I had been using TetherTool's "Jerkstoppers" for a little while, and though they worked well enough, I still didn't feel totally comfortable with this little dangly piece of plastic attached by a little tiny thread. I kept looking around and saw that they recently acquired the rights to sell the "TetherBlock" which had been created by someone else and TetherTools bought it from them. The TetherBlock is a solid piece of metal that has grooves on the underside cut for three sizes of cables. The smaller the cable size, the more "snaking" it does along a precut path on the underside. You snake the cable in the grooves and then attach the block to the bottom of your camera. There are threads so you can attach your tripod plate on after installing the block to your camera. Installation is a little wonky - it will take you a few tries to learn where the optimal place for the cord length so that you have enough coming out the end to plug into the side of your camera. Once you do find that length, make some little marks on the cable so next time you have guides to help you put it on quicker. It takes a few minutes to get it attached and screwed on. Once it's on, there is no way that your cable is going to come out by tripping on the cord connected to your computer. This sucker is locked down. The only way it can come out now is if someone yanks on the little bit of slack that comes out of the side of the camera. I don't forsee that happening, so this is a great solution. There is a very minimal learning curve when messing around with it the first few times trying to find that optimal spot for the cord and the length, but once you learn that, it's pretty smooth sailing from there. I use this on both my Canon 5DmkII as well as my Mamiya DF with a DM33 medium format digital back. Both work perfectly, and the Block has grooves for both sizes of tethering cable. The cable for the DM33 is really thick, and it works perfectly. The downside to this? The price. 99 bucks for a hunk of metal with grooves cut into it is crazy expensive. If it was 49.99 I'd plunk down the cash no problem, but at 99, I hesitated for a good while before buying one. Of course, after my first day using this I was sold on it, but still ... 99 bucks ... ouch! I think this is pretty much the best/strongest way to have tethering support for your camera - no matter what brand. If you have a local store that sells these, bring your camera in and a tethering cord and see if you can try one out. I'd definitely recommend getting this, but at pretty much 100 bucks I'd say do some research prior to purchasing. Hey tethertools - 99 bucks is crazy expensive.

if you shoot tethered this item is indispensable. without it you will eventually trip on the cable and damage the camera's usb slot which is expensive to replace

The tether tool block allows you to secure your tether cable as well as having threaded females to attach a tripod plate to the bottom. Would strongly encourage the device for anyone tethering their camera to a computer

This is a perfectly normal functioning tether block. It’s built to last made of quality materials. I like this product.

I really didn't want to spend the $$ for this tiny piece of metal, but after so many stressful tether connections dropping while on set, I decided to try this out to see if it would help. Since using it I haven't had a SINGLE issue in connectivity. Same laptop/camera/Capture One version that I used to have so many connection issues with, and this little TetherBlock came in and saved the day. Now I refuse to shoot without it! It's a lifesaver.

The Tether Block is rock solid. It holds Tether Tools cables very securely thus completely protecting your camera ports during tethered shooting. The quality of the product is excellent. You can attach your tripod quick release plates to the bottom of the Tether Block which makes for very convenient shooting. Like other reviewers I find the price outrageous. When Manfrotto quick release plates go for $25 I see no reason why this product is priced at $90. This kind of pricing does not encourage me to look at the wider range of Tether Tools products which is a shame as they have a very innovative product line.

Great product, perfect for what it is intended for! I use it for my D810. This should cost maybe $25 at the most, its overpriced imo but in the world of photography... You have to pay to play! Works like a charm!
