YJINGRUI Spring Balancer 3~5kg(6.6~11lbs) Retractable Spring Tool Balancer Balancer Retractor Without Self-Locking 1.5m Wire Rope Hanging Holding Equipment

i have about 9ft of tesla wall connector cable draped across the garage and this is able to retract it up to the ceiling fine with tension to spare. pull/retract action is very smooth. its all metal build is heavy so make sure to use a large gauge like #20 hook screw and make sure its screwed into stud not drywall. you do not want this heavy thing crashing down from the ceiling. i also used zipties and secured to the hook and to the backup loop in the unit just in case. forget the cheap sub $15 units as they are junk like the first one i bought only lasted 5 months before cable detached from the inside. this unit seems like it will last a long time.

I used this to make a cable retractor for a client. Basically, we connect a sling with wires wrapped up to the balancer. When we pull an AV equipment rack out of the closet, the wires extend. When we push it back, they retract and are pulled up off of the floor so they don't get caught in the wheels of the rack.We may use a lot of these. BUT, I noticed no change when we tried to adjust the tension. The adjustment screw seems to make no difference. We had enough wires/cables to use the full tension without damage, but this will not always be the case.

Excelente producto, muy buen tiempo de entrega

Works great. Make sure you go slow when you retract whatever you attach, especially if the tension is set high. If you let it retract too fast the cable might get off track. Happened to me once but I was able to fix.

Using to hold EV charge cable from center of garage, works really well. Wasn't sure it was going to be strong enough, but I actually lowered the resistance.
