Establish the overall outer sizes of the letterbox - this will establish whether it is a 12" Standard, 12" Slimline or 10" Standard.
Lift up the inner flap and measure across the postal slot (Width x Height).

Check the diagram to compare the postal slot sizes and fixing centres.
In some cases there may be some minor modification needed to the hole in the door.
They can easily be used on timber doors to tidy the existing aperture and add draughtproofing to the aperture area of the door. When it is particularly windy and cold the presence of a draught sealed letterbox can be worth its weight in gold! The spring loaded action of the flap means no rattling in the wind!
The nice thing with these products is they are well made and consider all aspects of modern design to make life easier. A choice of finishes and sizes helps too and to be honest they are easy to fit. We've come up with a Help Guide to walk you through the simple steps to replace your uPVC letterbox. A simple tape measure is all that is needed on your part.
Just use a slightly damp cloth with mild soapy water to keep your letterplates looking new! You don't need household cleaners, in-fact you mustn't use cleaners on these surfaces particularly chrome as it can pit the surface. It's like all things, a little bit of care and it could last a life time!
When fitting a letter box always ensure the smaller sleeve is on the outside, that way when pushing the post through the box it will not hit a ridge. It will also save the Posties finger nails! |Try not to overtighten the screws and make sure the screw positions are accurate otherwise the plate could bend ever so slightly and could cause the flap to stick.
A uPVC letter box is easy to replace as long as you follow some basic guidance. Use our Help guide to take you through the 3 easy measurements you need to take.
The basic concept of a modern day postal plate is two letterplates being attached to a plastic sleeve each side of the door. They come together to ensure the aperture through the door is closed off. Unlike timber doors where the letterplate is just a flap on the outside and maybe a Tidy on the inside the letterbox found on a uPVC door is a complete unit. That said they can also be used on wooden doors.
uPVC letterboxes are generally very good weather performers. They come with seals on the flaps and the flaps have spring resistance so every time the flap is used it resoundly closes back down onto its sealing strip. These flaps are cycle tested to ensure that they will stand up to a good level of abuse. Part of the design is such that the letterplates open sufficiently so that over-extending is not a problem. Many can open 180 degrees to help the Postie get large amounts of mail through and the aperture is sufficient to get A4 sized letters through them comfortably.
The most important part to measure when replacing a letter box is the aperture size through the door. You will need to compare your current one to the new one to ensure that you can fit the sleeve through the aperture cut through your door. If it is slightly bigger than the one you are purchasing that should be ok as the sleeve will be clear but if the aperture is smaller than the new aperture then you may need to consider opening the aperture up slightly with a file or similar tool.
Fitting can be as simple as just screwing the two halves together and can take only a few minutes to do. If you find that the flap is tight or even having difficulty closing this may be down to the screws being overtightened and bowing the letterplates ever so slightly. Just ease them off slightly if that is the case.
One of the questions most commonly asked by customers refers to the finish of the letterbox. The one to watch out for is the polished chrome finish as this does not really have much protection where polluted air or sea air is present. The one thing that catches most people out with polished chrome letterboxes is using general household cleaners on the letterplate. This will cause the letter plate to degrade and pit where polished chrome is concerned. A great alternative to polished chrome is the polished silver finish. This is not quite as mirror-like but reflective and looks good. It will also stand up to the elements much better like the other finishes which are anodised. Anodising the letterplates gives a good hard-wearing surface and the finish lasts much longer. Always be careful not to use chemical based cleaners on a finished surface and only use mild soapy water. That should be all that is needed to keep your product in tip top condition.
