- This sleeved 12 inch upvc letterbox has plenty of room and is well sealed against the elements, containing a brush seal and a rubber letter plate seal built into the plastic casing.
- Sold as a complete box set including an integral telescopic sleeve that will accommodate door thicknesses between 20 to 80mm.
- The external letter plate will open upto 180 degrees and contains an anti snap spring. The spring is strong and stops a rattling letterbox in windy conditions and also ensures a good weather seal against facing rain. A supressor for the letterplate reduces noise anyway and coupled with great acoustic sealing this is one where the Postie can act by stealth!
- There are two fixings on this 12 inch letterbox and they are spaced at 280mm centres. The fixings are achieved by two central threaded lugs that ‘clamp’ the letterbox onto the door. Provision is also made for 4 fixings each side – discussed below.
How to check the 12 inch Numail Anti Snap uPVC Letterbox will fit your door
Check the diagram under the main picture which shows the aperture shape and size needed. This will show you what to measure as the sleeve has to pass through the aperture in your door. This video explains everything you need to know - How To Fit a uPVC Letterbox.
Fixing the LB20 Anti Snap letterbox
This 12 inch anti snap upvc letterbox has two ports or lugs which accept a bolted thread (supplied as several lengths). Usually the aperture through the door is elongated at the end each side for the lugs to go through. This is known as the 'clamp method' and is the best form of fixing. If your existing letterbox is face fixed from each side with four screws then this is still achievable but will require a little bit of diy skill! All you need to do is take out the metal ports off the one side of the letterbox using a spanner and then drill through the pre-moulded fixing positions in each corner. The moulded positions are handy as they make it easier to set a position for fixing but again they will require a little 'spot' through with a drill. If they are not required then you won't even know the markings are there!
Taking care of your letterbox
Like everything these days if you look after things they will last a long time and this 12 inch upvc letterbox is no exception. When it comes to the finish of the letter plates then all you need to remember is keep solvents and chemicals of any kind away from the surface. Just use a dry cloth to keep the letterplate clean.
