The LiftMaster 41A5807-3 chain and cable kit is a one-piece replacement chain and cable assembly for select Chamberlain and LiftMaster chain drive garage door openers installed on a 7 foot door. It is commonly associated with PD752 and PD752D applications.

This assembly is tied to both opener model and door height. If the chain is the wrong length, the opener may not travel correctly or may not tension properly.
After replacing chain and cable hardware, opener force and travel should be checked according to the opener manual. Do not increase force settings to overcome a binding door or damaged rail.
Yes. This chain and cable kit is used for select 7 foot door chain drive opener applications, including PD752 and PD752D references.
No. Door height changes the chain and cable length. An 8 foot door normally requires a different chain assembly.
PD752D is one of the common model references for this part. Still match the opener parts diagram before ordering.
