Product Details

ADB-012 is designed to be fully mortised into hollow metal doors. A heavy duty, mortised, automatic ‘flat back’ drop seal to suit installation to metal door rails.

It features a high efficiency mechanism, which lifts the seal clear of the floor as soon as the door is opened by a few millimetres; resulting in lower door operating forces.

Requires no power connection. Self-levelling on uneven floors; seal height can be adjusted independently of fixing screws.
