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

Excellent craftsmanship. Product as described and functions as expected. Mulitple items purchased and yet to be dissatisfied. Thank you kindly. I look forward to continuing doing business with you and your company in the future.

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

These worked out very well. Exactly what was needed to complete the DIY project.

Nice addition to the end of the rail as your stopper/bumper. About 10 seconds to install!

These seem to be built well enough and fit without issue. However when you try and tighten them the bolt is only sitting on the rubber, so as you tighten it the bolt sinks into the rubber bumper. The issue with this is it doesn't provide enough clamping force and allows the stop to be slid out of the channel even after fully tightening. I added a washer under the bolt head to allow for more distribution of clamping force on the rubber and this allowed for a more positive clamp on the channel. Just be aware so you don't pull a trolly out of the channel and damage or injure someone.

Was what I ordered

Good trolley limiters

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.

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!

Use these as part of the bike rack setup and they work as designed. Easy to install and stops the rollers from come off the rail.

As advertised no issues. Just wish price was lower.

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.

They are great and do there job with no problem
