Envirotech Systems Limited prioritizes quality above all else. Our Fire Rated Letter Boxes are meticulously crafted using the finest materials and undergo rigorous testing to meet and exceed industry standards. You can trust our products to perform flawlessly when it matters most.
The mail drop flap uses an inward sprung hinge to stop the flap from falling out of the box when exposed to fire. The mailbox features an opening that uses an intumescent seal which expands when exposed to a large increase in temperature which closes the air space available and thus restricts the flow of oxygen into the mailbox. The access door lock includes a flip cover.
The Fire Rated Letter Box system range is specifically designed to increase the safety and security of occupants against fire and is particularly suited to multiple occupancy residential buildings.
