QWORK Spring Balancer, 11-19 lbs Retractable Balancer with 5 Ft Long Wire Rope and Hook, Retractable Spring Tool Hanging Holding Equipment

These work as specified. Work very well to retract hydraulic hoses up and out of the way when I need to disconnect and move hydraulic equipment.

Bought this bad boy over a year ago to use with my Domino Festool (aka my favorite overpriced precision biscuit machine). At 11.46 lbs (5.5 kg), it doesn't seem heavy… until you've been using it for days and your arms start questioning all your life choices. So, I got creative. I mounted this spring balancer to a trolley wheel system that glides smoothly in 1 5/8" Unistrut, then bolted the whole thing to my ceiling like some kind of genius engineer. After dialing in the perfect counterbalance, my Domino now floats effortlessly, just hovering a foot above my workbench, waiting for me to grab it like Thor’s hammer—except I don’t need superhuman strength. With this setup, I knocked out 500+ domino joints in a week with zero fatigue and the balancer held up like a champ. Pro tip: Use a safety backup chain to prevent disaster if anything ever fails—because a tool AND a balancer crashing to the floor is the kind of chaos nobody needs. Bottom line? Take the time to set this up right, and you’ll never go back. Your arms (and sanity) will thank you!

Works great!

Funcionaron bien y de buena calidad! Ojo no trae autobloqueo.

The item arrived as expected. Easy to use, and well made. Adjusting the tension was super easy. I used it in conjunction with a portable circular saw using a custom jig - worked perfectly!
