Lettergard Protected Letterbox

Protect your premises from letterbox arson attacks with the Lettergard Protected Letterbox (LGD1). Designed to stop flames at the entry point, Lettergard helps prevent fire and smoke spreading into your building—providing peace of mind when the property is unattended.

How it works
Lettergard uses the advanced Pyrocloud™ solid-state suppression system. If heat is detected, the integrated unit automatically activates and releases an eco-friendly extinguishing aerosol that floods the internal space and suppresses flames within seconds—helping to stop a small attack becoming a major incident.

• Lockable access door to protect post and sensitive documents
• Clean, minimalist white finish suited to a wide range of environments
