Mapp Caster Sliding Barn Door V Groove Cast Iron Wheel Kit 3"x1-1/4" with 3/8" Axle & Nut

This 3" x 1-1/4" cast iron wheel with 3/8" bushing, allowing for a 3/8" axle and nut, is our most popular choice for those building their own interior sliding barn doors. V groove wheels are design to be used on inverted angle iron track, however they can also be used on flat surfaces. While not designed to run on flat iron, there is a .24" opening in the v groove and can be run on 3/16" flat bar. *Note - The 3/8" bushing allows you to capture the wheel into place when squeezed on both sides while still allowing the wheel to spin freely. This can be done because the bushing is just longer than the hub of the wheel.
