Compatible with the EM3500 (Single), EM3500M (Monitored), EM3500D (Double), and EM3500DM (Double Monitored), the AMLB4’s horizontal sliding adjustment ensures precise armature alignment — critical for achieving the full 280kg holding force of your maglock.

Its sliding track design extends the mounting surface beyond the frame edge, positioning the lock body so the armature plate on the door leaf seats flush against the magnet — maintaining full holding force and preventing premature lock wear.\u003c\/p\u003e\n\u003cp\u003eConstructed from \u003cstrong\u003ehigh-strength aluminium alloy\u003c\/strong\u003e with a satin anodised finish, the AMLB4 is lightweight, corrosion resistant, and blends cleanly with modern commercial door hardware. Pre-drilled fixing holes reduce installation time, and fire-rated compatibility ensures your door assembly maintains its safety certification.
