Mr Kelly Wall Integrated Letterboxes from Robert Plumb are manufactured from 2.5 mm 316 marine grade stainless steel. They measure 200 mm high x 350 mm long x 200-400 mm deep. Their design incorporates a large wall integrated door which makes removing mail an easy task and they come with a safety lock and weather flap as standard.
These telescopic letterboxes double in size from 200 mm to 400 mm making them ideal for magazines and A4 envelopes. Their internal telescopic sleeve is rebated on all sides by 20 mm and this allows for adequate space for both the front and back plates to overhang the space in the wall.
Robert Plumb will also make custom designed stainless steel products on request.
