Prime Line Products B 530 Screen Door Roller Assembly

Product Description

The PRIME LINE PRODUCTS B 530 is a sliding screen door roller assembly insert designed as a direct replacement for worn or damaged door rollers. The assembly features an aluminum frame with a high-density polyethylene inner housing and a high-density polyethylene roller wheel. It inserts into the bottom or top rail of a sliding screen door and is secured with the included screws. The roller housing adjusts up and down to set the correct door height and travel position. This part is typically installed by glaziers, screen door technicians, or knowledgeable property maintenance professionals.

This roller assembly is suited for residential sliding screen door repair and replacement applications. It is commonly found on Columbia brand sliding screen doors but is also used across a wide range of other screen door manufacturers and styles. The package contains 6 assemblies per unit, making it practical for multi-door service calls or inventory stocking. When comparing to an existing roller, confirm the dimensions and overall design match the original part before installation.

Installation Notes

Installation is typically performed by screen door technicians or general maintenance trades. Before servicing, remove the screen door from its track to allow safe access to the roller channel at the top or bottom rail. Use the included screws to secure the assembly, then adjust the roller housing height to achieve proper door alignment and smooth rolling travel. Confirm the door moves freely in the track and latches correctly before returning it to service.
