4 Wheel P2750-EG Trolley Assembly Light Duty Electric Hoist Trolley Roller for use with 1-5/8" Wide or All 1-5/8" or Taller Strut Channel,Unistrut Accessories,Superstrut,2 Pack

Exactly what I was looking for to make a sliding barn door. Very heavy duty and very nice quality.I can’t believe there are people reviewing this with claims about the “fit”. It fits perfectly in the section of uni strut I used it in, maybe it’s their uni strut that isn’t the right size, they detail the exact dimensions of this product in the product description.

These works very well with strut Model# R1000T10PGItem# 3846852From Lowe's

Rollers fit perfectly and work without issue

They work great role, incredibly smooth and seem to be a great quality. However, they’re pretty sloppy in the channel. I wish they fit snugger.

Did not use them as my project plans changed. But they seemed to he good quality

These rollers are impressive. They fit the track snuggly with just a little play. They are able to operate smoothly without binding. Great purchase.

As someone who frequently needs to move heavy loads in my workshop, this trolley has been a game-changer. Its sturdy construction and smooth rolling wheels make maneuvering effortless, even with bulky items. The electric hoist function is a lifesaver, allowing me to lift and lower objects with ease, saving both time and energy. Overall, I highly recommend this trolley to anyone in need of a reliable solution for transporting heavy loads.

I was a little late to the Strut Channel party, so I'm just learning about all the wonderful toys I can make from the various parts. I happened to have a couple of pieces of strut lying around and need some bike storage space. Well wouldn't you know that right where I've been storing the bikes under a semi-enclosed space, or really just a covered space there is a stairwell that is long and tall and all the space above it is just sorta wasted and empty. My thought is to mount the strut channel and build hangers that drop down from the trolleys. Some ratchet straps to hoist them up at the top of the stairs and slide them out to the far wall where they will be way above anyone head using the stairs. The trick is going to be mounting the strut. I seem to recall a kind of hokey staging setup when building that area of the building. The two far ends aren't bad but since it's longer than one piece of strut I need to get to the middle to screw it up. Hope I don't screw it up.
