About this item
- CHECK SIZE & FIT BEFORE PURCHASE – Letterboxes come in 10" or 12" sizes and suit different door depths. This model is 12" (30.6cm) and fits doors 40–80mm thick only. Some doors may also have slimline letterboxes, which are longer and narrower. Please measure your current letterbox and door depth carefully to ensure compatibility.
- ANTI-SNAP FLAP – The flap opens a full 180 degree for easy access and to prevent it from snapping off when opened too far.
- ADJUSTABLE SLEEVE – The telescopic design means the letter box can be adjusted to fit doors between 40mm to 80mm in thickness. Our letter box will fit most uPVC, Composite & Timber doors.
- DIMENSIONS – The letter box overall size is 306mm x 70mm and the internal dimension of the sleeve is 254mm x 37mm. The distance between the screw hole centres is 280mm. Suitable for apertures between 285mm x 50mm up to 295m x 60mm.
- INTERNAL DRAUGHT EXCLUDER – The integrated brushes help prevent draughts. Plus, an internal water seal prevents water leaks as it stops water getting into the door or panel.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
