The Z102-Z is a mortice overhead limiting stay which limits the opening angle of a door to 90 degrees. It is primarily used on timber doors. It’s reversible so, it’s suitable for either left hand or right hand doors. It can also be used on double action doors.
The channel is morticed into the top of the door, and the head plate fits under the soffit. It is manufactured from mild steel with electro zinc-plated finish. There is a leaf spring at one end of the channel, and by reversing the channel it can be fitted to either, hold the door open (leaf spring fitted nearest the door jamb) or function as a non-hold open stay (blank end fitted nearest the door jamb).
Since this limit stay is often used on outward opening external doors, all parts are electro zinc plated to extend life. The channel is 357mm long x 30mm wide x 12mm deep. The minimum door leaf width for doors fitted with butt hinges is 610mm. This product is also supplied complete with seven No.6 x 19mm BZP countersunk wood screws.
