Securitron FMK-SW Gate Lock - Flex Mount Kit for Swing Gate

The Securitron FMK-SW is a Flex Mount Kit that mounts a high-security magnetic gate lock on a swing gate, the bracket system that extends electronic access control out to gates and fences. Maglocks are designed to bolt onto a door and frame, but a swing gate has no flat frame to mount to, so the FMK-SW provides the pre-formed post channels and plates that let you mount the lock and strike cleanly on round gate and fence posts. It's part of Securitron's Flex Mount Bracket System, designed specifically for the 1200 lb M62FG Magnalock and the 2000 lb GL1 Gate Lock, and it lets a professional, high-security gate lock platform go together in minutes without special tools.

What the FMK-SW does and why a gate needs it

This is worth understanding, because mounting a maglock on a gate is a different problem than mounting one on a door. A maglock needs the electromagnet and the strike (armature) to meet squarely, but a swing gate is an open frame on round posts with none of the flat surfaces a door provides. The FMK-SW solves that: it gives you bracketry that clamps to the posts and presents proper flat, adjustable mounting surfaces for the lock and the strike, so the magnet and armature align correctly for full holding force.

The kit permits the electronics to be mounted on either the fence post or the gate post, giving you flexibility in how you lay out the installation. The lock and strike brackets are reversible, which doubles the mounting variations so you can adapt to your gate's swing and post layout. It's the swing-gate version of the Flex Mount system, matched to gates that swing open rather than slide.

Built for durable, adjustable, weldable installation

The FMK-SW is heavy-duty hardware for an outdoor security application. The brackets are 8" tall by 3/16" thick zinc-plated steel for durability and long outdoor life. The post brackets come pre-drilled and the lock and strike brackets pre-tapped, so installation is largely a bolt-on job, but the entire system can also be welded for a permanent, maximum-security mount. A key practical feature is the superior adjustability of the lock and strike before final welding, so you can get the alignment exactly right and then lock it in. Pre-configured kits include all the lock mounting hardware and post shims, and the system fits a maximum 3" round post.

Why choose the Securitron FMK-SW

Securitron is a leading access-control hardware brand, and the FMK-SW is the proven way to bring maglock security to a swing gate. You get heavy zinc-plated steel brackets, pre-drilled and pre-tapped parts for fast bolt-on installation, the option to weld for permanence, reversible brackets for layout flexibility, and all the mounting hardware and shims in one pre-configured kit. For a perimeter gate or fence opening that needs electronic access control with the holding force of a Securitron Magnalock or GL1 Gate Lock, the FMK-SW is the bracket kit that makes it possible.

One thing to confirm before ordering: the FMK-SW is the swing-gate version, designed for the M62FG Magnalock or GL1 Gate Lock on a maximum 3" round post. Verify your gate swings (rather than slides), that your posts are within the 3" round size, and that you have the matching lock. The lock itself (M62FG or GL1) is ordered separately.
