Frequently Asked Questions
Q: What door thickness is compatible with this door reinforcement lock?
A: This aluminium alloy door reinforcement lock is designed to fit doors with a thickness between 35 mm and 45 mm, which covers the majority of standard interior and hotel-style doors.
Q: Does this door lock require any tools or keys to operate?
A: No keys or special tools are needed. To disengage the lock, simply pinch the top and bottom of the device together and slide it sideways toward the door hinge. The spring-loaded design makes it quick and intuitive to use.
Q: Can this lock be used on outward-opening doors?
A: This door reinforcement lock is specifically designed for inward-opening doors. It is not intended for outward-opening doors, as the mechanism relies on the door frame and inward swing to provide its rated holding force.
Q: How high should I install the lock to keep it out of a child's reach?
A: For enhanced child safety, it is recommended to install the lock above the door handle height — ideally near the top of the door frame — so that young children cannot reach or operate it independently.
