These are possibly the largest caster wheels i've ever seen. They are durable, easy to install, and work great! The only downside is that there is no locking mechanism, but i should have taken that into consideration on purchase.

Product is as described. Was well packaged and arrived promptly. Good overall and seems to hold the weight they are rated at. These are cheaper and better than what’s available from harbor freight.

Wheel material is rubbery, grippy and rolls smoothly. Smooth rolling, very sturdy, swiveling is smooth. Rolls well over hardwood floors.

The locking mechanism is easy to engage and disengage. The easy way to release the lever is to use one finger to flip the lever out of the lock position.
