81-279 has been used as a replacement. The adjustment screw sits slightly higher, but the wheels roller nice than this old tank tread style. Take a look and see what you think. You may also want to check the screw before putting the door back in the frame. If the adjustment screw can't be reached after installation, put a shim inside the slot to bring the roller out a little. Get back to us and let us know how everything works out. |
