Are you having trouble sliding your screen door open or closed? Have you checked your rollers/roller assemblies? Don’t replace the entire door. For a fraction of the cost of a new door, replace those worn-out rollers. This is a very popular sliding screen door corner used by Arcadia, Guardian and a variety of other sliding screen door manufacturers. It is diecast with an adjustment screw that would adjust the Prime-Line part B 515 style roller (sold separately) that has been installed onto the corner's roller pivot arms. The diecast corner fits into the sliding screen door frame holding the bottom or top rails and the side stiles together. Order yours today and have your door slide like new. Color: Yellow.
