Macwood PSB automatic locking bolts are the pneumatic equivalent of an electrical solenoid bolt, however with significant advantages over their electrical counterparts. PSB locking bolts will have a minimum force of 50N to retract the bolt in the event of an air failure, in normal operation this will be in excess of 200N. All bolts are operated by spring and air pressure. The PSB range includes units designed to lock doors with rails (pin bolt) and to lock rail-less glass doors (fork bolt), (suitable for less-secure access control doors). Units are available to suite single or pairs of doors.

PSB bolts can be integrated with most access control readers and exit switches. Bolts can be linked to the fire alarm, to unlock upon activation of the fire alarm. Break Glass.
