Replace failing or worn parts on your LiftMaster RSW12UL swing gate operator with our original-manufacturer LiftMaster repair parts from North Shore Commercial Door. These are replacement parts specifically designed for your RSW12UL LiftMaster residential/light commercial vehicular gate controller. We also have LiftMaster APS encoders and APE assemblies for your gate opener. These parts are all guaranteed by LiftMaster and backed by our easy-returns guarantee.
Replace a battery (or have an extra on hand) when you buy our LiftMaster 29-NP712 12-volt replacement battery. Protect the internal parts on your operator from the elements with a LiftMaster dust cover or replacement operator cover. Pay less for a replacement gate operator transformer or locks and keys. If you don't see the part you need on our illustrated EPV (Exploded Parts View) page, contact our LiftMaster pros by email, toll-free telephone or 'Live Chat.' Our 35-year-old company has earned top customer satisfaction ratings every year.
