RHKING 4 Wheel Light Duty Trolley Assembly Roller Trolley Easy Bolt Installation 2PCS for use with 1-5/8" Wide and All 1-5/8" or Taller Strut Channel

I got these to run down a track for a router fixture and it works great for the saddle.

I mounted two of these to an electric hoist and run them in a 1-5/8” Unistrut track fastened to the underside of the garage roof trusses. This allows lifting loads through the attic hatch and then sliding the hoist and load over to the attic floor. This makes moving heavy or bulky items from the floor or truck to and from the attic much easier and safer.

I used four of these on an attic storage lift in my shop. They fit the 1-5/8" unistrut as good as the original equipment. I suggest using all three mounting holes in the bracket due to the small M5 bolts needed for the holes, plus the bracket is not as heavy duty as the unistrut bracket, but worked just fine for my application.

Noisy

There isn't room to use bolts with washer to mount the unistrut and have the rollers pass through. You have to drill the unistrut for you mounting hardware.

This roller trolleys are perfect for hanging my 14' kayak from the 1 5/8" strut channel. The more expensive trolleys have a higher capacity but I don't need to hold that much weight.

Will be using to lift and store my bike in the garage.

It’s a nice product but the Attachment point it’s not very thick metal
