LOX DB1260PTL Electric Drop Bolt – Narrow Style, Fail-Safe (Power to Lock), 300kg, Fire Rated
Overview
The LOX DB1260PTL is a premium electric drop bolt engineered for narrow-frame swing doors and glass door installations where a standard-width lock simply won’t fit. With a slimline 25mm faceplate and just 35mm body depth, it slots cleanly into a 44mm door frame while delivering a formidable 300kg holding force via a 14.5mm stainless steel bolt. Operating in Fail-Safe (Power to Lock) mode, it automatically releases during a power failure — keeping occupants safe and your installation compliant with Australian fire egress requirements.
Description
Drop bolts are the preferred locking solution for swing doors where a maglock isn’t suitable — particularly on narrow aluminium frames, frameless glass doors, and timber doors where a recessed mortice mount is required. The DB1260PTL’s slimline profile solves the most common installation challenge: fitting a high-security electric lock into a frame that’s too narrow for standard hardware.
The built-in Door Status Sensor (DSS) uses a reed switch to provide real-time door position feedback to your access control panel, while the selectable 0, 3, 6, or 10-second re-lock time delay gives installers flexibility to match the lock behaviour to the door closer speed. Integrated surge protection (MOV varistor) guards the internal circuitry against voltage spikes — a practical feature in Australian commercial environments where power quality can vary. Dual 12VDC/24VDC compatibility and a 4-hour fire rating round out a specification sheet that covers virtually every commercial installation scenario.

Frequently Asked Questions
What is the difference between Fail-Safe (PTL) and Fail-Secure (PTO)?
The DB1260PTL is Fail-Safe (Power to Lock) — it locks when power is applied and releases when power is cut. This is the correct configuration for most commercial and fire-rated door applications in Australia where safe egress during a power failure is required. If you need the door to remain locked during a power failure, the Fail-Secure (Power to Open) DB1260PTO is the alternative.
What door frame width does the DB1260PTL fit?
The DB1260PTL has a 35mm body depth and is designed to fit into a 44mm door frame. Its 25mm faceplate makes it suitable for narrow aluminium, timber, and glass door frames where standard-width locks cannot be used.
Does the DB1260PTL include door position monitoring?
Yes. The DB1260PTL includes an integrated Door Status Sensor (DSS) via a reed switch, providing real-time door position feedback to your access control panel.
What is the re-lock time delay and how do I set it?
The re-lock delay is selectable at 0, 3, 6, or 10 seconds and is set via an internal switch. This allows you to match the lock’s re-engagement timing to your door closer speed, preventing the bolt from striking the frame before the door is fully closed.
Is the DB1260PTL suitable for fire-rated doors?
Yes. The DB1260PTL carries a 4-hour fire rating to Australian Standards (AS), making it suitable for use on fire-rated door assemblies in commercial buildings.
Do you ship Australia-wide?
Yes. We ship to all states and territories including NSW, VIC, QLD, WA, SA, TAS, ACT, and NT. Contact us for bulk order pricing and project quotes.
