Support Defence Point L1A is situated on the ridge line overlooking the main road from Ghajin Tuffieha to Zebbiegh. It is a Category B design with no apparent observation turret. One of the machine gun emplacements has concrete reinforcing running from the base to the first floor. It has later been used as a aviary.
An outbuilding has been built with concrete and corrugated iron shuttering adjacent to the pillbox. This was to expand the living area.
