The LiftMaster 041A4795 is a screw drive hardware bag that includes the sprocket coupling for select garage door opener rail repairs.
It is used in compatible LiftMaster and Chamberlain screw drive applications where the rail coupling hardware needs replacement.
If the coupling failed because the rail is binding or the screw drive assembly is worn, replacing only the hardware bag may not solve the problem. Inspect the full rail drive path.
Do not operate the opener with damaged screw drive coupling hardware. A loose or failing coupling can affect rail drive movement and may cause additional opener damage.
This is a hardware bag that includes the sprocket coupling for compatible screw drive rail applications.
