Liftmaster 90-PGR, PARKING GATE RADIO MODIFICATION KIT
The LiftMaster 90-PGR is a radio modification kit for commercial parking gate and barrier gate operators. It is used when a BG770 or BG790 style barrier operator requires a factory-style radio-control modification so the system can work with an external radio receiver or access-control signal. In parking applications, this can allow authorized users to activate the barrier through a compatible remote or receiver setup.
This kit is not the same as purchasing a remote control or receiver. It is the operator-side modification hardware and wiring used to support the radio input arrangement. References for this kit commonly mention limit switch wiring and a bracket, with BG770 and BG790 as the primary compatibility targets. The installer should verify the operator control terminals and site access-control requirements before installation.

Technician Note
Do not confuse this kit with the radio receiver or handheld transmitters. The receiver and remotes must still be compatible with the site frequency, credential system, and access-control design.
Before Ordering
- Confirm the barrier operator is BG770, BG790, or supported PG / HBG / BG model
- Verify the system calls for 90-PGR or G90PGR
- Confirm the external receiver and transmitter technology used at the site
- Review control terminal wiring before installation
- Test radio input, arm travel, loops, and safety controls after installation
Professional Advisory
Radio-control modifications should not bypass vehicle detection, safety loops, or barrier gate safety requirements. A qualified gate technician should complete and test the installation.
