Uniview OEA-MS12-280Z Z-Bracket for 280kg Maglock Armature

The Uniview OEA-MS12-280Z is a 180 x 50 x 50mm aluminum Z-bracket that carries the maglock armature plate so it meets the magnet when the door will not line up on its own. It works with both the Uniview OEA-ML12-280 and OEA-ML22-280.

====

Sometimes the lock body goes up exactly where it should, and then the armature plate on the door simply does not reach it. The Uniview OEA-MS12-280Z fixes that. It is an aluminum Z-bracket that screws to the door and carries the armature plate forward until it sits flush against the magnet. It measures 180 x 50 x 50mm, weighs 0.48kg, and is also listed as UNV OEA-MS12-280Z.

Uniview OEA-MS12-280Z specifications

• Shape: Z.
• Job: carries the armature plate, not the magnet body.
• Material: aluminum alloy.
• Dimensions: 180 x 50 x 50mm.
• Weight: 0.48kg.
• Compatible locks: OEA-ML12-280 and OEA-ML22-280.

How a Z-bracket works

A maglock only holds when the plate is in full contact with the magnet face. Any gap between the two cuts the holding force sharply, or stops the door locking at all. Improvised timber or sheet-metal packing can shift over time and tilt the plate, so a matched bracket the same 180mm length as the plate is the better choice. The Z shape has a step that moves the plate from the plane of the door face to the plane of the lock body.

The common pairing with the L-bracket

With the single OEA-ML12-280, the lock body bracket is the OEA-MS12-280L and this Z-bracket carries the plate. Many installs use both: the L lowers the body below the frame head and the Z brings the plate out to meet it. With the double OEA-ML22-280, the body bracket is the OEA-MS22-280L, and the Z remains an option for the armature plate.

Installation tips

• Mount the lock body first, close the door, then mark the plate position exactly before drilling for the Z-bracket.
• On steel doors use screws suited to the sheet thickness; on timber use wood screws long enough to bite.
• Cycle the door several times and confirm the plate meets the magnet across its full face with no gap.

Typical jobs in Saudi Arabia

• Office doors in administrative buildings.
• Internal warehouse doors that staff open with a card.
• School admin entrances and staff rooms tied to an access control system.
• Interior doors in villas and residential buildings released from the intercom monitor.

OEA-MS12-280Z, OEA-MS12-280L or OEA-MS12-280U?

The Z and the U carry the armature plate; the L carries the lock body. The Z is the heaviest at 0.48kg with a 50 x 50mm profile. The U is lighter at 0.32kg and made for 8 to 12mm frameless glass. The L (250mm, 0.27kg) is for the body of the single OEA-ML12-280 only.

Frequently Asked Questions

When do I need the OEA-MS12-280Z?

When the armature plate on the door cannot reach the magnet face after the lock body is mounted.

Does it work with the OEA-ML22-280 double lock?

Yes. It is an armature plate bracket for both the OEA-ML12-280 and the OEA-ML22-280.

Is it suitable for frameless glass doors?

For 8 to 12mm frameless glass, the OEA-MS12-280U U-bracket is the one to use instead.
