Drawer runners have evolved from being 1 piece of timber that slides on top of another, into today's ball bearing style. The ball bearing drawer runners have a high load capacity and are virtually indestructible. Hard, steel balls run in unison providing an even stability and a smooth action in all applications. All of our metal filing options come with a 10 year warranty, so it is the only type of runner we can use that will stand the test of time.
It would not be advisable to purchase a filing cabinet for commercial use without these ball bearing runners. There are a lot of cheaper types on the market that feel great when you open and close the drawers empty on the showroom floor, but they will not give you the same luxury under weight.
