Securitron Flex Mount Bracket Kit

The Flex Mount Bracket System is an intuitive set of mounting brackets designed exclusively for use with the 1200lb holding force M62FG-SASM Gate Magnalock® and the 2000lb holding force GL1 Gate Lock. Using pre-formed post channels and plates of varying lengths, a professional looking high security gate lock mounting platform can be assembled in minutes without special tools. Post Shim Brackets are used to adapt both small and large Post Brackets to pole/post sizes smaller than 2" or 3" respectively in 1/8" increments - 1-7/8", 1-3/4", 1-5/8" 2-7/8", 2-3/4", 2-5/8", etc. When more than two shims are used together on a single post, welding the bracket to the pole/post is recommended. All necessary mounting hardware including four Post Shims is included with each Flex-Mount Kit.


  • Pre-configured kits include all lock mounting hardware and post shims
  • Post brackets are pre-drilled, lock and strike brackets are pre-tapped
  • 8" tall x 3/16" thick zinc-plated steel provides durability and long life
  • Lock and strike brackets are reversible doubling the mounting variations
  • Allows simple bolt on installation, or the entire system can be welded
  • Allows superior adjustability of lock and strike before final welding
  • Permits electronics to be mounted on either the fence post or gate post
