FMK stands for flex-mount gate lock bracket kits. Coming in several models, this is a set of mounting brackets designed exclusively for the M62FG-SASM gate magnalock, as well as the 2000 lb. holding force GL1 gate lock. It will function with the GL1 when post separation is between 1” and 3-3/4”. Even without SASM, the FMK-SL will function when post separation is between these measurements. This uses pre-formed post channels and plates of varying lengths, which gives it a clean look for the high-security gate lock mounting platform. This can all be done without special tools. The different models are as follows; the FMB9-4 is the post shim kit for the FMK in a set of 4. The FMK-SL is the flex mount kit for sliding gates, and the FMK-SW is for swinging gates.

It is recommended that an initial physical survey and assessment be done of the area where the FMK will be installed to determine the optimal method of mounting the previous installation. The post shim brackets are used to adjust the large and small post brackets to the pole or post. Sizes smaller than 2” or 3” respectively in 1/8” increments – ergo 1-7/8”, 1-3/4”, 1-5/8”, 2-7/8”, 2-3/4”, and 2-5/8” and etc. It is highly recommended to weld the bracket when two or more shims are used together on a single post.

Each flex-mount kit includes all the necessary mounting hardware, including the four post shims and multiple fasteners. It’ll also include all the lock mounting hardware. The post brackets are also pre-drilled, the lock and strike brackets are pre-tapped. The lock and strike brackets are reversible, doubling the mounting variations.

It is 8” tall x 3/16” thick; its zinc-plated steel provides durability and long lasting life. It allows superior adjustability of lock and strike before finalizing the welding. It can also be done with simple bolts to install, or the entire system can be welded. Finally, it permits electronics to be mounted on either the fence post or gate post.
