## Customer Reviews

### ⭐⭐⭐⭐ Too wide for standard unistrut.
*by B***B on March 1, 2024*

I ordered by mistake not realizing that the width was too wide for a single strut track. The product seemed well made, however I returned the item without using. The info in description was correct but I assumed that the dimensions were all compatible and sadly was wrong.

### ⭐⭐⭐⭐⭐ Smooth roller
*by S***S on November 15, 2024*

These will roll so easy you better make sure the drops are in place and solid . Roll forever and a mile.. great product , delivery was perfect price well below the agriculture box store prices ( tsc is retarded $)

### ⭐⭐⭐ Some of the bearings have pits.
*by K***R on December 3, 2022*

Needed to order two sets to get two good hangers. The first had a really pitted roller and the other set had a bit less but still flawed. Together I have one good set. Able to return so just extra time and effort to get a good set. No desiccant in sealed packaging so I would guess that’s the problem.
