Key Features

Type and Design: Surface-mounted deadbolt with a double-cylinder mechanism (keyed on both sides). It features a contoured handle for a modern look and is ideal for securing sliding doors without obstructing movement.
Security Standards: Complies with Australian Standard AS4145.2-2008 for locks, offering reliable deadbolting to prevent unauthorized entry.
Compatibility: Often used as a standalone lock or paired with additional latches/levers. It’s suited for residential applications but can fit some commercial setups.

Maintenance and Repairs

Common Issues: Over time, mechanisms can stiffen (eg handles not closing from outside), Faulty bolts (eg incorrectly angled) have been reported in rare cases, potentially allowing doors to be pushed open if locked.

Longevity: Built tough for Australia’s weather, but regular checks prevent wear, especially on moving parts.
