280KG Z&L Mounting Bracket Guide: Heavy-Duty Glass Door Maglock Installation

280KG Z&L Mounting Bracket: Heavy-Duty Glass Door Installation

For heavy glass doors and narrow aluminum frames, the SK-ZL280 Z&L mounting bracket adapts your 280kg maglock to surfaces where direct mounting isn’t possible — with the strength to hold a heavy-duty lock.

Why a 280KG Bracket Needs to Be Stronger

A 280kg maglock generates more holding force than a 180kg unit. The bracket has to handle that extra leverage — that’s why the SK-ZL280 is precision-machined from thicker magnesium-aluminum alloy with a reinforced structure. It’s not just a 180kg bracket scaled up; it’s engineered for the higher forces of a heavy-duty lock.

Glass Door Installation Without Drilling Glass

The Z-bracket mounts to the aluminum frame around the glass, and the L-bracket holds the lock body in the exact right position. The result: a clean, secure installation on 10-15mm thick glass doors — without ever touching the glass itself. The oval wiring slots make cable routing neat and adjustable.

What’s in the Box

The SK-ZL280 set includes three pieces: the L-bracket that mounts the lock body, the Z-bracket that connects to the door frame, and the mounting plate. Pre-drilled holes match the 280kg maglock exactly, so installation is fast and secure. The sandblasted silver finish resists rust and looks clean on premium doors.

Where the 280KG Bracket Fits Best

  • Heavy glass storefronts – commercial entrances with high traffic.
  • Narrow aluminum frames – frames too narrow for direct mounting.
  • Metal entrance doors – when the frame profile doesn’t match.
  • Gate access – heavy-duty gate and fence entry points.
