This top bracket is designed to support the upper section of a sliding window sash by providing a shaped guiding point inside the window frame. Made from plastic with a white finish, it fits smoothly into common frame styles and supports consistent sash positioning during movement. The bracket features a 17/32" height, 1/2" upper width, 1" length, and 27/32" lower width, creating a structured guiding area that helps keep the sash aligned throughout travel. These dimensions form a defined contact surface that supports the sash as it moves along the window track. The 1/2" upper width helps stabilize the sash at the top section, while the 27/32" lower width forms a broader contact point that reduces side shifting during movement. The 1" length provides extended guiding support, helping the sash maintain a centered path. Its height helps position the sash at the correct level inside the frame, supporting smoother upward and downward travel. The plastic construction forms a lightweight yet stable guiding shape that fits into standard frame recesses without unnecessary movement.
