LiftMaster K94-36591 Junction Box with Cable Kit
The LiftMaster K94-36591 junction box with cable kit is used on compatible dual swing gate installations where the primary operator must communicate with and power the secondary actuator. It provides a protected connection point and the cable assembly needed for clean wiring between the two sides of the gate system. This kit is especially important on dual LA400 and LA500 style systems because poor splices, damaged underground cable, water intrusion, or incorrect conductor count can cause the secondary leaf to move incorrectly, lose synchronization, or stop communicating with the primary control box. The K94-36591 should be matched to the original LiftMaster dual-gate wiring layout and installed with proper weather protection and conduit practices.
Compatible With
LiftMaster LA400 and LA500 dual swing gate operator applications where a primary-to-secondary communication and power cable/junction box kit is required. Also listed for LA500 master/secondary wiring with 40 ft of 6-conductor cable in some references.

Technician Note
This is not a universal low-voltage wire kit. Confirm LA400 or LA500 dual-gate wiring requirements, cable length, conductor count, and junction box location before ordering.
Before Ordering
- Match the manufacturer part number on the original component whenever possible.
- Confirm the operator model, model suffix, and generation before ordering.
- Compare connector style, wire count, battery size, enclosure layout, and harness routing where applicable.
- Use the LiftMaster parts diagram as the final fitment reference when model listings conflict.
- Do not bypass monitored safety devices, reset circuits, interlocks, or fault-protection wiring.
Professional Advisory
Gate operator wiring, battery, reset switch, and enclosure repairs should be completed with power disconnected and with the gate secured from unexpected movement. If the operator has high-voltage wiring, damaged insulation, missing safety devices, water intrusion, or repeated fault conditions, have the system inspected by a qualified gate technician before returning it to service.
Product Q&A
What is the K94-36591 kit used for?
It is used as a junction box and cable kit for compatible LiftMaster dual swing gate systems, commonly LA400 and LA500 applications.
Does this kit work on single gate installations?
It is normally used when a primary and secondary actuator must be connected. A single-gate installation may not need this kit.
How long is the cable?
Several references list the kit with 40 ft of 6-conductor cable, but actual kit contents should be verified before ordering.
Can this fix a secondary gate leaf that will not move?
It may help if the issue is a damaged interconnect cable or junction box, but the actuator, board, batteries, and programming should also be checked.
Should the cable be run in conduit?
Gate operator control wiring should be protected and installed according to the operator manual and local code. Avoid exposed or water-prone wiring.
