A: Yes! The door bolt is designed for straightforward DIY installation. It comes with the necessary mounting hardware, and most users can complete installation in just a few minutes using basic tools like a screwdriver. No specialist knowledge or professional assistance is required.
Q: How does the anti-theft locking mechanism work?
A: The anti-theft bolt uses a reinforced zinc alloy sliding latch that locks firmly into place, resisting lateral force and tampering. When engaged, it prevents the door or gate from being pushed open from the outside, providing an additional layer of security beyond standard door handles or knobs.
