Drop-Bolt Lock Ensures Alignment

Dortronics Systems Inc. introduced the Dortronics 3412 Series Drop-Bolt Locks

Dortronics Systems Inc. introduced the Dortronics 3412 Series Drop-Bolt Locks as a heavy-duty locking solution for single- or double-acting inswing or outswing doors, including Herculite frameless glass doors. The unit’s automatic alignment sensor simplifies installation and helps ensure a working lock. The 3412 Series Drop-Bolt Locks include an intelligent logic circuit that keeps the drop-bolt retracted until the door has been closed and is aligned to ensure engagement of the lock bolt. The design also features a fully adjustable mechanical alignment to compensate for excessive door gap, up to 3⁄16-in. wide.
