4pc - 3" Storage Rack Caster Wheels (Adapts to Boltless Self Locking Shelving Racks)

The 3" Storage Rack Caster Wheels are well-built -- nice and strong to accommodate heavy racks. Easy to install. Note that if you install the bottom shelf *after* you screw on the castor wheels, which is highly likely, you may have to slice off two corners of the shelf because otherwise the shelf will hit the bolts used to attach the castor wheels to the vertical rack rails and not drop into place. But that's a minor thing. I used these wheels on huge 24" x 60" x 72" racks which are HEAVY to begin with, and even when the racks are loaded with stuff, they are pretty easy to move around thanks to these castors. It might be good to add a few drops of oil to the castors before you install them.

A well designed shelving accessory, which is suitable for the stated purpose. I also received excellent customer service from the vendor when dealing with a special concern related to my order.
