The PRIME LINE PRODUCTS B 714 is a spring tension roller assembly designed for use in sliding door and window hardware applications. Each pack contains two concave rollers with a 1-1/4 inch outside diameter, providing a ready-to-install replacement for worn or damaged roller assemblies. The spring tension design helps maintain consistent contact and smooth travel along the track. Installation is typically handled by glaziers, general contractors, or experienced DIYers performing door or window hardware service.
This roller assembly is suited for residential sliding doors and windows where concave-profile rollers are required. The concave roller profile is intended to seat properly on standard cylindrical or rounded track systems. It is commonly used as a direct replacement in applications where the original roller has worn flat, cracked, or lost spring tension, resulting in difficult or uneven sliding operation.
Designed as an OEM-style replacement roller assembly for residential sliding door and window systems requiring a concave 1-1/4 inch outside diameter spring tension roller.
Installation is typically performed by a glazier or general contractor familiar with sliding door and window hardware. Remove the door or window panel from the track before servicing the roller assembly. Inspect the track for wear or debris before installing the new rollers. Follow all applicable building codes and manufacturer guidelines for hardware replacement.
