STP Z&L Mounting Bracket for 500kg Magnetic Lock Door Access Control

A magnetic lock requires the lock body and the armature plate to meet flush and parallel when the door is closed, so that the full magnetic holding force is applied across the entire mating surface. If the door and frame are not in the same plane, or if the maglock body cannot be mounted in a position where it faces directly opposite the armature, a Z&L bracket provides the angular offset needed to achieve the correct alignment.

The Z&L name refers to the shape of the bracket assembly: a Z bracket is used on the lock body side and an L bracket is used on the door or armature side, together providing the angular offset and standoff distance to align the two magnetic surfaces correctly despite the geometry of the door and frame.

At 500kg specification, this bracket is matched to 500kg magnetic locks and is rated to handle the mechanical stress of the full holding force without bracket deformation. Undersized or inadequate brackets are a common cause of maglock failure under attack, as the bracket rather than the magnetic surface absorbs the force applied to the door.

For access control installers completing magnetic lock installations on doors where the geometry requires an angled mounting solution across London and the UK, the STP Z&L bracket for 500kg locks is the standard mechanical accessory for achieving correct maglock alignment.

Key Features

• Z&L mounting bracket for 500kg magnetic locks on non-coplanar door frames
• Provides angular offset to align maglock and armature plate correctly
• Rated for 500kg mechanical stress from full holding force application
• Prevents misalignment that reduces effective magnetic holding force
• Required where door and frame geometry prevents direct flat maglock mounting
• Matched to 500kg maglock body for correct structural rating
