LiftMaster IBGARM Barrier Arms 18-24 Ft

3-Inch Aluminum Barrier Arm for TECHNA Industrial Gate Operators

The LiftMaster IBGARM is a 3-inch diameter aluminum barrier arm engineered exclusively for use with the TECHNA IBG24DC industrial barrier gate operator. Available in 18 ft and 24 ft functional lengths, these arms address wide-lane access control installations at industrial facilities, loading docks, and restricted-access sites where standard commercial arm lengths fall short. Construction is durable aluminum extrusion with secure fasteners throughout. The arm joint uses bolts, nuts, and washers for stability and is reinforced by a torsion bar for added strength at the pivot point.

All components for each arm ship in a single carton box, supporting on-site assembly without multiple deliveries. Arms are field-customizable and can be cut down to match the required lane width. Neither variant includes integrated LED lighting; LED-equipped arms are not available for the IBG series at this time.

Key Features

• 3-inch diameter aluminum extrusion construction with secure fasteners throughout the arm length.
• Arm joint reinforced by a torsion bar for added pivot strength; uses bolts, nuts, and washers for stability.
• All components ship in a single carton box for on-site assembly; field-customizable and cuttable to required lane width.
• Compatible exclusively with LiftMaster TECHNA IBG industrial barrier gate operators; not compatible with CBG or PBG models.
• Available in two functional lengths: 18 ft (IBGARM18) and 24 ft (IBGARM24).
• Fixed arm installation only; the IBG operator does not support swingaway or breakaway arm configurations.

Conclusion

The IBGARM18 and IBGARM24 are sold separately from the IBG24DC operator and must be ordered to complete the installation. These arms are not compatible with LiftMaster CBG or PBG operators. The clearance height referenced in installation documentation is measured from the base of the operator, not from grade. Confirm site clearance requirements before selecting arm length.
