Prime-Line 1 in. Nylon Ball Bearing Wheel Screen Door Roller Assembly, Aluminum Frame

This is a clear vinyl guide used on frameless tub enclosures. It is used by a variety of manufacturers of shower doors. A dual durometer extrusion process fuses 2 different styles of clear vinyl to create a guide with soft fins on the center guide while the rest of the guide is rigid. The soft fins stabilize the glass & allows for smooth, rattle-free door movement. Easy to install - it snaps into track base.
