The LOX DB1260Electric Drop Bolt has been designed to be used on double action (swing through) doors or as an additional locking device in conjunction with an Electric Strike in single door applications. The DB1260has a 25mmwide face plate and is therefore applicable on narrow style frame installations. It is available in either “Power to Lock” (Fail Safe) or “Power to Open” (Fail Secure). The DB1260product range provides several glass-door mounting accessories. We do not recommend using this product on Emergency Egress Door.
