Locinox Surface Mounted 'US' Mortise Cylinder Gate Lock

Locinox Surface Mounted 'US' Mortise Cylinder Gate Lock (LUKYJ5)

The Locinox LUKYJ5 Surface Mounted Gate Lock is a heavy-duty locking solution built for secure access control on ornamental, aluminum, steel, and chain link gates. Designed around the standard 1-1/8" US mortise cylinder, this lock combines the convenience of widely available cylinder compatibility with the durability needed for long-term outdoor performance.

Built with a weather-resistant aluminum housing and stainless steel internal locking components, the LUKYJ5 is designed to handle demanding outdoor environments while maintaining smooth and reliable operation. The lock provides keyed access from both sides of the gate, making it a practical option for residential, commercial, industrial, and facility gate applications.

The LUKYJ5 Series is available in both Keyed Different and Keyed Alike configurations. Keyed Different locks operate with unique keys for individual access control, while Keyed Alike versions allow multiple locks to work with the same key for added convenience across larger properties or multi-gate installations.

Each lock includes Schlage C keyway 5-pin cylinders that are 6-pin drilled, along with matching keys. The cylinders can easily be replaced or rekeyed if needed to match existing facility locks. Both the stainless steel latch bolt and deadbolt are continuously adjustable up to 3/8", allowing easier alignment during installation and long-term gate adjustments.

Available in Black and Silver finishes, these locks are designed for 1-1/4", 1-1/2", and 2" square gate frames. The silver models may also be adapted for round chain link gate frames when paired with the appropriate adapter hardware.
