LOX AMZB4D-LP Double L & Z Bracket – EM3500D & EM3500DM Maglock Mounting for Inward-Opening Double Doors
Overview
The LOX AMZB4D-LP is a professional-grade, adjustable L & Z bracket engineered specifically for mounting the LOX EM3500D and EM3500DM series double electromagnetic locks on inward-opening (swing-in) double doors. The L & Z configuration provides the correct geometric offset to keep the armature plates flush against the magnets when the door swings inward — ensuring maximum holding force and long-term security. A trusted solution for security installers and integrators across Australia.
Description
When a double door swings inward, mounting a maglock directly to the frame is not possible — the door leaf would collide with the lock body on opening. The AMZB4D-LP solves this with its combined L and Z plate geometry, positioning the lock on the frame while keeping the armature plates correctly aligned on each door leaf. Without the right bracket, even a high-quality double maglock will underperform or fail prematurely.
The bracket’s multiple mounting points allow precise horizontal and vertical adjustment, accommodating minor frame irregularities without custom fabrication — saving installers time on site. Constructed from high-grade aluminium alloy with a satin anodised finish, it is lightweight, corrosion resistant, and suited to the demands of 24/7 commercial operation in Australian conditions. All necessary hardware is included for a complete installation.

Frequently Asked Questions
Do I need this bracket for every double maglock installation?
Only when your double door opens inward. For outward-opening double doors, the LOX AMLB4 adjustable L-bracket is the correct choice. Using the wrong bracket type will result in misalignment and reduced holding force.
What is the difference between the AMZB4D-LP and the AMZB4D-BLK?
The AMZB4D-LP has a satin anodised silver finish and is designed for the standard silver EM3500D and EM3500DM maglocks. The AMZB4D-BLK has a matte black powder coat finish and is matched to the EM3500D-BLK and EM3500DM-BLK black series locks. Dimensionally they are identical.
Can I adjust the bracket after installation if the alignment is off?
Yes. The AMZB4D-LP features multiple mounting points for both horizontal and vertical adjustment, allowing you to fine-tune armature plate alignment on site without replacing the bracket.
Is the bracket corrosion resistant?
Yes. The satin anodised finish provides excellent resistance to corrosion, making it suitable for Australian coastal and high-humidity environments. For fully exposed outdoor installations, additional weatherproofing of the lock itself is recommended.
Does the kit include all necessary fixings?
Yes. The AMZB4D-LP includes all hardware required for a complete installation. Always refer to the LOX installation guide for your specific lock model for wiring and mounting instructions.
Do you ship Australia-wide?
Yes. We ship to all states and territories including NSW, VIC, QLD, WA, SA, TAS, ACT, and NT. Contact us for bulk order pricing and project quotes.
