LiftMaster GPINLCK Gate Arm Pin Lock — LA400 / LA412
LiftMaster GPINLCK Gate Arm Pin Lock — LA400 / LA412
The LiftMaster GPINLCK is the gate-arm pin-lock accessory identified for documented LA400 and LA412 actuator installations. It is designed to help prevent unauthorized disconnection of the actuator from the gate while retaining the prescribed means of disconnecting the arm for manual access. This mechanical attachment accessory is different from an automatic electric gate lock or the actuator’s internal release mechanism. Match the pin location, actuator generation and mounting arrangement before ordering, and plan how authorized personnel will access the release during a power failure.
Compatibility — Models, Versions and Exclusions
| Model or selection point | Compatibility requirement |
|---|---|
| Documented LA400 / LA412 arrangements | Confirm the approved pin location and current accessory instructions. |
| Manual gate access | Follow the actuator and pin-lock release procedures with the gate secured. |
| Automatic electric gate locks | Different function and installation requirements. |
| Actuator release keys | Separate function; do not assume a pin-lock key operates the internal release. |
| Other actuators or pin sizes | No universal fit or approved modification established. |
Preserve a Safe Manual-Access Plan
A secured actuator connection must still permit the manufacturer’s intended service and emergency procedures. Identify who will hold the required keys and how the gate will be controlled when the arm is disconnected. Do not remove the connection from an unsecured gate: slope, wind or an unbalanced installation can cause movement as soon as the actuator no longer restrains it.
Inspect the gate bracket, pin holes and actuator attachment before fitting the accessory. Excess wear or distorted mounting parts need correction rather than concealment with a locking pin. Compare the actual connection with the approved instructions, especially if the gate has been repaired or modified. After installation, verify clearance through travel and demonstrate the intended manual procedure to authorized personnel.

Before Ordering
- Identify the LA400 or LA412 generation and gate connection.
- Verify the pin-lock accessory against the installed brackets.
- Inspect pin holes, attachment alignment and gate movement.
- Confirm package contents, key requirements and the manual-access plan.
Package Contents and Separate Requirements
This listing identifies the GPINLCK pin-lock accessory. Confirm the current kit for the supplied pin, locking components, keys and attachment pieces. An actuator, gate bracket set, control box, electric gate lock and replacement internal-release mechanism are not promised as included. Do not assume one package secures both actuators of a dual-leaf gate; determine the required installation quantity from the actual layout.
Safety Warnings — Read Before Installation or Service
- WARNING: Disconnecting an actuator can allow unexpected gate movement. Secure the gate and use a qualified gate installer before disturbing the attachment.
- Isolate applicable power and keep people clear of the arm and gate during installation or release checks.
- Do not drill out worn brackets or substitute an unverified locking pin to approximate fit. Repair damaged attachments and preserve required emergency access.
- Verify secure retention, free travel and all required safety-device responses. Use the manual disconnect only under the conditions specified by the operator manufacturer.
Related Products and Important Differences
- LMRRUL monitored photo eye — a separate protection option only where the exact operator and control revision approve it; not a universal legacy retrofit.
- LMWEKITU monitored wireless edge kit — a separate edge communication system for approved controls and resistive edges; not a replacement for this mechanical or electrical service part.
Frequently Asked Questions
Is this an automatic electric gate lock?
No. It secures the documented actuator connection mechanically.
Does it replace the internal release mechanism?
No. Those components and procedures are separate.
Will it fit any swing-gate actuator?
No. Match the documented LA400 or LA412 arrangement.
Can the gate move when the arm is disconnected?
Yes. Secure and control the gate before removing its connection.
