Wall Mounted Large & Small Wheel Barn Door Roller Floor Guide

Both use two rollers and require 7/8 in wall-to-door clearance. The dual-wheel guide uses two identical 3/4 in rollers. This guide uses a 1-1/4 in roller on one side and a 3/4 in on the other — the larger roller rolls more smoothly over textured or rough door surfaces. If your door has a smooth factory finish, either works. If it has a rough or textured bottom edge, the large roller here is the better choice.

The roller on the wall side of the door needs 7/8 in of clear space between the wall surface and the back face of the door for the bracket to mount correctly and the roller to operate. Measure this gap before ordering — if there's less than 7/8 in, consider the felt-lined large roller guide instead, which has no wall clearance minimum.

Match to your door's actual thickness: standard for 1-1/4 to 1-3/4 in, extended for 1-3/4 to 2-1/4 in. The extended uses a slightly longer bracket to span the wider door.
