Description

The Astroflame telescopic letterbox system range is specifically designed to increase the safety and security of occupants against fire and is particularly suited to multiple occupancy residential buildings.

The Astro Eco Telescopic Letterbox is a stylish, ABS framed, telescopic letterbox with metal flaps fitted with a high performance intumescent liner around the telescopic sleeve section.

The letterbox flaps open to 180° and the adjustable telescopic sleeve can be set to suit 40mm - 80mm
door thickness.

Acoustic and thermal performance features include brush pile draught excluders, integral sound dampening bumpers and a fully sealed backplate.

During a fire the intumescent liner rapidly expands and seals off the letterbox opening, preventing the spread of fire and smoke whilst maintaining the integrity of the fire door assembly.

Available in 10” Standard (272mm x 70mm) and 12” Commercial (306mm x 70mm) sizes.

Cut out required is 241mm x 57mm for standard size letterbox and 274mm x 57mm for commercial size letterbox.

Adjustable to suit door thickness from 40mm – 80mm and tested for use up to 1050mm from floor level.

Both 10" and 12" sizes have a black ABS frame and are available with Satin Aluminium, Chrome Plated, Stainless Steel, Polished Silver or Polished Gold letter plate flaps.
