2PK 1" STL BB Roller

This sliding screen door roller assembly insert has a high density polyethylene frame with an adjustable high density polyethylene inner housing and steel ball bearing roller. The assembly inserts into the bottom or top of the sliding screen door by snapping it into place. The roller housing adjusts to the correct position needed. This style is found on Columbia sliding screen doors but is also used by very many other screen door manufacturers. Please note dimensions and design when comparing with old roller.1 in steel ball bearing roller.
