Prime Line Products D 1518 Glass Door Roller Assembly

Product Description

The PRIME LINE PRODUCTS D 1518 is a sliding glass door roller assembly designed for smooth, reliable door operation. It features a 1-1/4 inch steel ball bearing roller mounted in an adjustable steel housing. The housing adjusts to accommodate minor variations in door frame tolerances, making it suitable for replacement work where exact original dimensions may have shifted over time. This assembly is installed by glaziers, general contractors, and experienced maintenance technicians working on residential and light commercial sliding glass door systems. The steel construction provides durability under the repeated load cycles typical of high-traffic door installations.

This roller assembly is used in sliding glass door applications where the existing roller has worn, flattened, or seized. The adjustable housing allows the installer to fine-tune the door height and tracking after installation. It is packaged in a carded format with a quantity of 6 units per package, making it practical for contractors handling multiple doors or keeping replacement stock on hand. Typical install scenarios include residential patio doors and light commercial storefront sliding panels.

Installation Notes

Installation is typically performed by a glazier or qualified contractor. Remove the sliding door panel from the track before accessing the roller assemblies at the bottom of the door stile. Use the adjustment screw on the housing to set proper door height and ensure the door glides evenly within the track after reinstallation. Inspect the track for debris, wear, or deformation before installing new rollers, as a damaged track will shorten roller service life.
