Prime-Line 7235 Gray Plastic Convex Wheel Mirror Door Bottom Roller personal protective equipment

Prime-Line 7235 Mirror Door Roller

This Prime-Line 7235 roller replaces worn hardware on sliding mirror doors. It supports a maximum door weight of 40 lb using steel bearings inside a gray nylon wheel. The unit fits a 3/16 in mounting hole and includes the necessary installation hardware. It is built for residential closet door repairs.

Practical Limits of Nylon Wheel Construction

The nylon wheel resists corrosion but will deform under loads exceeding the 40 lb rating. Steel bearings reduce friction yet require a properly aligned track to prevent premature wear. The fixed 1 in wheel diameter cannot accommodate deeper or shallower channel profiles. Builders needing adjustable height or heavier capacity must choose a different assembly.

Capacity and Headroom for Closet Doors

This roller comfortably handles standard bypass closet doors weighing up to 40 lb. It runs out of headroom when doors exceed that weight or when the track geometry differs from the 1-29/64 in shaft length. The gray unfinished finish blends with most aluminum frames but offers no color match for custom trims. Installers should verify the 3/16 in hole spacing before ordering.
