SKTREX Trolley Roller Wheels Limit Trolley Assembly Positioning for Unistrut Strut Channel with 1-5/8" Wide and All 1-5/8" or Taller Strut Channel Pack of 2

Better and more professional than drilling and installing a bolt in the uni-strut to stop the trolley.

Strong construction and a perfect fit for the unistrut installed. They made a difficult positioning task much easier.

Definitely a stopper, work well on my project. Certainly could have made several different types of stoppers myself, but I wanted a clean professional look to it.

I got these as end stops for the upper rails on an x-y Unistrut hoist system that I installed I like that they were compact compared to some other styles to make full use of the space and that the c shape of the clamp helps set the correct width of the rails mine were the deep rail type and had gotten bent in on shipping so these end stops helped with that. my main complaint with these is that they do slip a little when the trolley hits them and you cant jut clamp them tighter because the clamping force goes through the rubber part not to big of a deal but if you use them for positioning or have a heavier trolley then you will want to check them from time to time and push them back in.

Good trolley limiters

Easy installation and works as designed

Great end stops. As they are tightened, the rubber core buldges out for a rubber bumper. The lower plate is fabricated to hold the unistrut closed at the bottom, which is a safety feature. These work well.

Received the parts installed in the Kindorf does exactly what it’s supposed to do fits very nicely would recommend it again

Used these in a uni strut track I put in my garage for a winch track, and they fit great, and work exactly as intended!

They are great and do there job with no problem

Does the job

I use it as a safety bumper for rated planned loads; and, so I don't drop my lifted load unintentionally at either end of rail.. I have no further comment. thx.

Good
