Prime Line Products N 7192 Bi-fold Door Bottom Roller 2 Pack

Product Description

The PRIME LINE PRODUCTS N 7192 is a bottom-mount concave roller assembly designed for solid wood bi-fold and sliding closet doors. Each assembly features a 1-3/16 inch brass concave ball bearing roller mounted on a stamped steel bracket. The roller rides on a floor-mounted metal track, providing smooth, low-friction door travel. The assembly installs into a mortised pocket at each end of the door's bottom rail, measuring 7/16 inch deep by 2-15/16 inches long. Two 3/4 inch screws secure the bracket in place. This kit includes two roller assemblies, supplying both ends of a single door panel in one purchase.

This roller assembly is suited for residential closet door applications where solid wood bi-fold or sliding door hardware has worn, cracked, or broken at the bottom rail. It is a direct repair component installed at the bottom of the door, not the track. Carpenters, general contractors, and knowledgeable DIYers typically handle this replacement during closet door refurbishment or routine hardware maintenance. The package quantity of six units makes it practical for multi-door jobs or stocking service inventory.

Installation Notes

Remove the door from the track before beginning any hardware replacement. Clear the mortised pocket of debris or damaged hardware remnants before seating the new roller assembly. Drive the two mounting screws firmly but avoid over-driving into the wood rail to prevent splitting. Confirm the floor track is straight and free of damage before reinstalling the door.
