LiftMaster Model J Elite Series. Contact DOORTEC for current warranty terms and motor sizing.

The LiftMaster Model J is the industrial-duty jackshaft commercial door operator — the correct specification for any commercial door opening where the door tracks go high or vertical rather than the standard horizontal configuration that a trolley operator requires.

Jackshaft (wall/hood mount) configuration — mounts beside or above the door opening rather than on the ceiling, the correct choice for high-lift doors where track geometry eliminates usable ceiling space, and for rolling doors and grilles where a trolley drive is not applicable

25 cycles per hour / up to 90 cycles per day duty rating — the same industrial-duty performance as the Model T trolley, in the jackshaft configuration required for high-lift and rolling door applications

Removable hinged electrical box cover — provides easy field access to control wiring and the internal board without requiring disassembly of the operator; a practical design feature that reduces service time on every maintenance call

High-lift and vertical-lift sectional door compatibility — provides motorized operation for doors that store sections more vertically than standard doors, required in facilities with limited horizontal ceiling space

Rolling door and grille compatibility — the jackshaft mount is the standard operator configuration for commercial rolling steel doors and security grilles, connecting to the door's drive shaft or barrel

myQ Smart Facility Access compatibility — same commercial facility monitoring capability as the Model T trolley, in the jackshaft configuration

Integrated timer-to-close, UL 325 compliance, and safety sensor compatibility — consistent with the full Elite Series commercial operator specification

The Model J is the specification for any commercial door application where a trolley operator is not appropriate — high-lift sectional doors, vertical-lift applications, rolling steel doors, and security grilles.

Model J Installation in Oklahoma City

The LiftMaster Model J Elite jackshaft commercial operator is DOORTEC's specification for Oklahoma City commercial facilities with high-lift sectional doors, rolling steel service doors, and security grilles. The jackshaft configuration is required for these applications because the door's track geometry or coil barrel design doesn't accommodate a ceiling trolley — the Model J's wall or hood mount is the correct operator for the job. DOORTEC installs the Model J throughout Oklahoma City, Edmond, Norman, Moore, Yukon, Midwest City, Guthrie, El Reno, and the OKC metro.

For Oklahoma City facilities evaluating the Model J against the MAXUM JDC, DOORTEC's commercial team can assess whether the JDC's 12"/sec DC motor, Wi-Fi myQ Facility connectivity, and battery backup justify the additional investment for your specific duty cycle and operational requirements. Call (405) 720-7107 for a free commercial site assessment.

Jackshaft Commercial Operators Tulsa & OKC

DOORTEC's Tulsa location serves the greater Tulsa metro with the LiftMaster commercial operator line including the Model J. Tulsa's substantial commercial and industrial building stock includes many facilities with high-lift sectional doors or rolling steel doors where the jackshaft configuration is the standard and correct operator specification.

For Tulsa and Oklahoma City facilities with rolling doors and grilles that also require floor-level chain hoist manual operation for large or heavy curtains, DOORTEC specifies the Model H hoist operator rather than the jackshaft. Contact us at (405) 720-7107 to discuss the correct configuration for your specific application.
