Prime-Line Screen Door Tension Spring with 1-1/8 in. Nylon Roller, 2 pk., B 713

Restore smooth operation to compatible sliding screen doors with the Prime-Line B 713 Screen Door Tension Spring and Roller Assembly. Designed to replace worn, damaged, or malfunctioning screen door rollers, this replacement assembly helps eliminate dragging, sticking, and difficult door movement while extending the service life of the existing screen door. Commonly used on Monar doors and other similar sliding screen door systems, it provides an economical alternative to replacing the entire door. Constructed with a durable diecast housing and a high-density polyethylene roller, this assembly is engineered for long-lasting performance and reliable daily use. The 1-1/8 in. diameter nylon roller is designed to roll smoothly along compatible tracks, helping restore effortless door movement. A unique loop-shaped flat tension spring mounted above the roller maintains proper roller engagement and consistent operation during opening and closing. This roller assembly is designed to fit the diecast corner housing used with Prime-Line B 712 (sold separately) and is commonly found on sliding screen doors used in Canada and other residential applications. Each package includes two roller assemblies for convenient replacement. Compare roller dimensions, spring configuration, and corner housing style with your existing hardware before purchasing to ensure compatibility.
