Prime Line Products D 1858 Patio Door Roller Assembly

Product Description

The PRIME LINE PRODUCTS D 1858 is a back-mount roller assembly designed for sliding vinyl patio doors. The steel housing measures 11/16 inches wide and 1 inch tall, with a 1/4-20 threaded mounting hole on the rear face for secure attachment. The assembly allows smooth, consistent door travel along the bottom track and is sold in a package of 6 units, making it practical for multi-door jobs or service inventory stocking. Installation is handled by glaziers, door technicians, or experienced general contractors working on sliding door repair and replacement projects.

This roller assembly is suited for residential sliding patio door applications where the existing roller has worn, cracked, or no longer tracks smoothly. The steel construction holds up to repeated cycling and the weight load typical of full-panel vinyl patio doors. The 1/4-20 threaded mounting hole allows for standard adjustment without specialty hardware. Each package contains 6 assemblies, supporting both single-door repairs and multi-unit service calls.

Installation Notes

Installation is typically performed by a door technician or qualified contractor. Remove the door panel from the track before servicing the roller assembly, and ensure the replacement unit matches the existing mounting configuration. Standard hand tools are sufficient for most installations. Confirm the 1/4-20 threaded hole aligns with the door frame adjustment slot before securing the assembly.
