These glide like butter. Silent, smooth bearings and perfectly round wheels with no wobble. The low profile design could be useful for projects where there is not a lot of room around the strut channel. These are sold as "light duty" and the term is relative here. For industrial or commercial use, yes they are light duty. With a 550lb weight rating and sturdy steel frames, these are more "heavy duty" for any household uses.They can work for gate or door tracks, large sliding drawers such as truck bed, garage, or shed storage for bulky items. I would not use them for hoists, winches or anything similar, but for many other projects these are great and certainly a bargain at the current price around $10/each.

I am using more and more Unistrut in projects these days - it is dirt cheap as far as semi-structural steel goes, you can get it just about anywhere like Home Depot and Lowe’s, and you have multiple rolling options like these to get motion into your projects. I am using these trollies to build a CNC router that folds up against a wall. This multi pack really makes it easy.
