The H300-2 has dimensions of 300mm width, 220mm height and 380mm depth, and is a front-entry front-retrieval unit (in-front, out-front). Where applicable, it complies to Secured By Design requirements (clauses 21.19 and 24.6).

It is designed to be incorporated into a bank of multiple postboxes suitable for both internal and external positioning with a choice of different casings, surrounds and support legs.

The model H300-2 can also be fitted with an internal fire extinguisher to create an anti arson fire proof letterbox. This is a much more economical solution to specifying a bank of fire rated letterboxes.
