Give your electromagnetic lock a versatile, secure and clean finish with the UL-280 bracket / U-/L-plate assembly. Designed specifically for glass doors and other applications where standard door mounting is tricky, this accessory ensures neat and stable alignment when paired with the SM-280 magnetic lock. Whether in a shopfront, boardroom, office entrance or retail fit-out, the UL-280 helps maintain both aesthetics and locking performance.
Built from aluminium alloy, this component comes in “L”, “U”, and plate styles, giving installers flexibility to match glass thickness, door style and frame geometry. It supports waterproof functionality for certain variants, weighs under 1 kg, and integrates smoothly with the rest of the SM-280 series (SM-280, SM-280-S, SM-280-T, SM-280-ST). Reliable, lightweight, and made to last.
