Economy Operator Available
R-Plus Doors offers the LiftMaster Model T operator as a way to combine the high-quality of an R-Plus door with the low cost of a power door operator.

This NEMA 1-rated solution is for indoor applications not needing a pedestrian door capability or mounting inside a freezer, a good solution in areas that do not encounter the harsh environments requiring a NEMA 4 rating. The Model T includes our standard safety-edge stop and a single-button security-protected remote that handles complete OPEN/CLOSE/STOP operations. Operator is pre-programmed for easy installation and troubleshooting.

The maximum door size using this controller is 10×10, still large enough to handle small lift truck or pallet jack traffic. Combined with a high-quality R-Plus Door, the LiftMaster Model T controller maintains traditional R-Plus high-quality standards and is serviceable nationwide by commercial door companies familiar with LiftMaster controllers.
