A. LETTERBOXES – THROUGH FENCE
B. PROTACOAT PRESERVATIVE AND FIRE RETARDANT COATING
Designed as a universal letterbox for installation through a variety of fencing, wall and gate materials, the Thru-Fence Letterbox is simple to install and has a large front plate area upon which street numbers can be fixed. It is a big box that will accept A4 sized envelope material and being of Australian manufacture and powder-coated aluminium construction, this a quality letterbox that will last.
Installation: After marking the brushwood panel with a felt tipped pen and using long handled pruning shears (or power saw) a rectangular hole is cut through the fence midway between a pair of horizontal panel wires. The box is then inserted through the hole from the front and hard against the box flange. Another loose flange is slid over the protruding box from the rear to clamp tight against the brushwood fence from both sides and the loose flange is then secured to the box using tek screws or pop rivets.
ausbrush ‘ProtaCoatTM’ is an “all in one”, water soluble, non hazardous preservative coating and fire retardant and can be applied in 2 clear coats to new brushwood fencing panels (made from the hardwood, Australian Melaleuca uncinata).
It lasts up to 5 years outdoors before re-application is required (20 years indoors).
In addition to other special ingredients, the formulation comprises phosphoric acid, formaldehyde and methanol.
ProtaCoat has fire retardant and preservative properties, is anti-fungal and mildly resistant to bacteria and is pest resistant. It sets clear, with the finished look on brush fencing panels matt clear with a slightly darker, richer look. It reacts to fire and heat making a chemical change in the wood and also nitrogen is produced displacing air/oxygen. Other uses include thatched roofs, decks, fencing, raw furniture, timber plywood and all natural wood material surfaces.
In the image above, the panel on the right has just had one coat of ProtaCoat applied, while the panel on the left is about to be treated.
The image below shows the finished Protacoat look after two coats and the panel has been fitted in a ready to stand pre-framed module 1760mm high x 1800mm wide with “in ground” leg length 640mm.
