A tri bolt door lock is a security lock with three locking points that extend into the door frame when you turn the key or knob. This multi-bolt design offers better resistance to forced entry than a single-bolt lock, making it ideal for main doors and high-use entry points.

Yes, a tri bolt door lock is highly suitable for main doors because its three-bolt mechanism secures the door at multiple points. This greatly increases strength against prying and kicks. It’s commonly recommended for entrance doors in flats, independent houses, and office cabins needing added protection.

You can install a tri bolt door lock yourself if you’re comfortable using basic tools like a drill and screwdriver. Follow the template or instructions provided with the lock, align the tri bolts with the strike plate, and test the movement. For perfect fitting, many users still prefer a professional carpenter.

Most tri bolt door lock models are designed to work on both wooden and metal doors, as long as the door thickness matches the lock’s specifications. Check the recommended thickness range before purchase. During installation, ensure proper drilling and alignment so the three bolts slide smoothly into the frame.

To maintain a tri bolt door lock, clean the keyhole and outer body regularly with a dry cloth and avoid harsh chemicals. Apply a light lubricant to the key and insert it a few times to keep the mechanism smooth. Tighten any loose screws and ensure the door alignment stays correct.
