A larger version of the LC8810
The power transfer lead covers are designed to ensure unbroken transfer of wires between the door and frame in electric locking situations.
The LC8811 is designed for use on doors which open more than 120°. NB. Not suitable for centrally pivoted doors.
When you specify this prep on your order, our frames come with a cutout to suit, and a mortar box. The lead cover is screw fixed to the face of the door frame.
