The LiftMaster 041B5351-7 is a DC power supply replacement kit for select LiftMaster belt drive garage door opener models. Current LiftMaster references list it for models 2500D and 3500, along with other compatible belt drive applications where the parts diagram calls for this kit.
This is the -7 version and should not be confused with the -6 power supply used on 2500B references. The suffix, connector layout, and opener model are all important when ordering power supply parts.
