Anti-burglary Hardware & Accessories
Latch Guard
A latch guard is a metal plate that covers the gap between the door and the frame, preventing intruders from tampering with the latch or lock. It is a simple yet highly effective way to reinforce door security, especially for commercial and high-traffic areas.
- Prevents Forced Entry – Stops burglars from using crowbars or pry tools.
- Adds Extra Strength – Reinforces vulnerable areas of the door.
- Durable & Long-Lasting – Made from heavy-duty materials.
- Easy to Install – Simple upgrade with a big security impact.
- Versatile Applications – Works for residential, commercial, and industrial doors.
Security Pin Hinge
Security pin hinges are specially designed door hinges that prevent doors from being removed, even if the hinge pins are tampered with. They are particularly useful for outward-opening doors, where the hinge pins are exposed.
- Prevents Forced Entry – Stops intruders from removing the door by pulling the hinge pins.
- Added Durability – Heavy-duty construction resists tampering and wear.
- Ideal for Outward-Opening Doors – Provides security where standard hinges fall short.
- Works with Various Door Types – Suitable for metal, wood, and security doors.
- Low-Maintenance Protection – Once installed, they require little upkeep.
Deadbolt
A deadbolt is a type of locking mechanism that provides enhanced security compared to a standard spring latch. It requires a key or a thumb turn to retract the bolt, making it more resistant to forced entry.
- Stronger Security – Harder to bypass than standard locks.
- Deters Break-Ins – Adds an extra layer of resistance against forced entry.
- Long-Lasting – Made from durable materials that withstand wear and tear.
- Affordable Protection – Cost-effective way to enhance home or business security.
- Variety of Options – Available in single-cylinder, double-cylinder, and smart lock versions.
Security Hinge Bolts
Security hinge bolts (also known as dog bolts or hinge protectors) are small steel pins installed in the hinge side of a door. They engage with holes in the door frame when the door is closed, preventing it from being forced open— even if the hinges are removed or compromised.
- Prevents door removal by securing the hinge side, even if the hinge pins are taken out.
- Engages directly with the door frame, reinforcing the weakest part of the door.
- Heavy-duty steel construction resists cutting and tampering.
- Works with most door types, including timber and metal doors.
- Ideal for outward-opening doors, which are more vulnerable to hinge attacks.
Carbine PS4000-6000 Lockset
Larnec offers a wide range of high-security locks designed to enhance anti-tamper protection and improve overall door security. The Carbine PS4000 – PS6000 series is a reliable locking solution that provide increased resistance against forced entry.
One key security advantage is the external door knob, which offers better protection against tampering compared to a standard external lever.
2-point Self-latching Exit Lever
Enhances security by automatically securing the door at two locking points upon closure. This ensures the door remains locked without needing to engage a separate deadbolt or manual locking mechanism.
- Tamper-Resistant Design – More secure than single-point latches, making it harder for intruders to bypass.
- Ideal for High-Traffic Areas – Perfect for industrial, commercial, and emergency exit doors.
