These Casters are a lifesaver to many customers when they have a unique or uncommon stem size and need to adapt and attach casters. Stemless Casters are explicitly made to accommodate any stem, bolt, or mounting hardware 1/2" diameter and under where a standard caster can not connect. Some equipment may have permanent stems but the customer may want to add casters; this is where hollow kingpin casters come in handy. Easily slide your stem directly through the center of our stemless caster, add a nut to the bottom of the stem to secure it, and you are now good to roll. This caster has wheel brakes to park your cart and prevent rollaway.
