This sliding screen door roller assembly insert has an aluminum frame with a high density polyethylene inner housing and steel ball bearing roller. The assembly inserts into the bottom or top of the sliding screen door with the included screws. The roller housing adjusts up and down to the correct position needed. This style is often 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.
