What’s the Advantage of Built In Post Boxes?

Built in post boxes are installed through a wall, so they aren’t easy to retrofit. This means planning at the design stage so the mailbox can be incorporated into the build. As this isn’t the most straightforward installation option, what is the advantage of built in post boxes?

Secure Post Box

The main advantage of built in post boxes is security. All mail is posted outside, it drops through the wall letter chute, into the internal, locked hold. This means there is a physical barrier that prevents unintended access to the hold.

When located on a boundary wall, it negates the need for posties to come onto your property. The same applies for through the wall apartment letterboxes – no one needs access to the building to deliver the mail.

All our built in post boxes include anti-theft baffle plates. These are small shelves that sit behind the letter flap. They make it very difficult for hands or tools to access mail. A great option for letterbox security is the LBD-042. If you would like additional hold capacity, we have the LFD-042 or check out Rolle!

Your Mail Saved from Pets

Once delivered, your mail is stored in a locked hold until you open it. All boxes are supplied with two keys, so you have a spare. No one can see if mail is piling up because you are away for a few days, or get their hands on it. Equally, your family pets don’t have the option to chew your important documents, snack on your birthday cards or drool over your packages!

A Discrete Mailbox

Another advantage of a through wall letter chute is that, from the outside, it is a neat letter plate. At the rear, can be a door or a hold box, depending on capacity. Either way, much of the bulk is hidden within the wall.

If your residential or business property has limited external space, this is a great option.

Installing a Through Wall Letter Chute

So, if a built in post box sounds like the ideal solution for your property, how is it installed?

As mentioned, it is easier to install this style of letterbox as part of a new build. It can be installed through the wall of your property, a porch extension or the boundary wall.

A built in post box is supplied in two parts, which slide together. The letter flap is positioned on the outside of the wall and the letter hold on the inside. The middle section is telescopic, so it offers the best fit for the wall size. Once the two sections are linked in place, the position can be secured and the post box sealed into place.

Many models are only suitable for installation into a double brick wall, as this offers sufficient space for the letter chute. If you are building a single brick boundary or porch wall, we recommend the W3-4XL model or the popular Sierra through the wall Parcel Box. Sierra is available with an anthracite grey powder coated galvanised steel or stainless steel letterplate.

UK Supplier of Quality Post Boxes

All of our post boxes are sourced from trusted manufacturers in Europe, who have achieved the ISO 9001 Quality standard. As specialists in their field, their models are built to last and come with a 2-year guarantee as standard.

We know you won’t want to hold up your build project, so our Buckinghamshire-based team provide a quick turnaround. Most in-stock products are packed and shipped and on-site within 48 hours.

If you are a building developer requiring a bulk order, we ask you to complete our enquiry form. We’ll get back in touch to discuss the options and lead times.
