WARNING: This product must never be installed on Fire Exits or Emergency Exits. Incorrect installation may obstruct emergency escape and may result in injury or death.

Trimec 118252-000 TB25 12-24Vdc power to open (PTO) drop bolt with 25mm faceplate. Delivers 1,000kg holding force and is designed for swing-through and double action door applications where an electric strike is impractical.

The bolt is deadlocked in the extended position with intelligent electronics that attempt to re-close the bolt 8 times, allowing swing-through doors to settle. Door position monitoring is integrated via a magnet in the strike plate. The drop bolt operates in both horizontal and vertical orientations. As a PTO device, the bolt retracts when power is applied and extends to lock when power is removed.
