William Dangar’s background is in landscape design and he runs a landscape architecture and consultancy firm in Australia. The Robert Plumb brand was established by Dangar as a direct result of the need for high quality, reasonably priced products of this nature. The product range includes mailboxes and furniture.

All goods are constructed to the highest quality, using premium materials (marine grade 316 stainless). The company was launched in September 2004 and, for architectural hardware, is now represented by 14 retail outlets throughout Australia. It is represented exclusively through Coco Republic for all furniture, mailboxes and other associated outdoor products. All goods are designed by Dangar and prototyped in Australia, before being exclusively manufactured at an offshore factory.

One of the popular products is the “Kelly Gang” mailboxes. Those who have seen the distinctive stainless steel mailboxes feel they resemble the armour of the notorious bushranger Ned Kelly. So the name stuck. The Kelly Gang architectural hardware range includes mailboxes, peg basket, washing lines and door-mats. The mailboxes have a sleek contemporary design, with a safety lock and a large door for easy mail removal.
