Prime-line MP6544 Bi-fold Door Top Guide Wheel 2 Pack

Product Description

The PRIME-LINE MP6544 is a bi-fold door top guide wheel designed for residential interior door hardware applications. The wheel is molded from nylon for quiet, smooth operation along standard bi-fold door track systems. It mounts to a spring-loaded steel base using a top-mount, self-adjusting design that accommodates minor track and door misalignment without manual readjustment. The nylon wheel measures 7/8 inch in outside diameter, making it compatible with most standard bi-fold track profiles. This pack includes two guide wheels, suitable for a single door or paired panels. Installation requires only basic hand tools and no specialized trade knowledge.

This guide wheel is used in residential bi-fold door installations, typically in closets, laundry rooms, and utility spaces. The top-mount configuration fits doors ranging from 1 inch to 1-3/8 inches thick. Compatible door brands include Acme, Cox, and other manufacturers using similar bi-fold hardware configurations. The self-adjusting base reduces the need for precision alignment during installation, making it a practical replacement option when original hardware wears out or breaks.
