The closest top sash guide we sell to your description is our 18-052. The top cap is 1-1/16 wide by 5/8" deep, the length is 1-1/4", the screw hole is 3/16" down from the top and the base that fits into the sash channel is 3/4". Unfortunately it only comes in white. We do have 18-015 in black. This has a 13/16" wide base, but that might be too tight. |
