Ultion Sweet 12" Letterbox Set Square Edge for uPVC Composite & Timber Doors

Ultion Sweet 12 inch letterbox with a square edge for uPVC, composite and timber doors 40-70mm thick, needing a 262 x 46mm cut-out.

Ultion Sweet 12" Square Edge Letterplate Set – the Ultion Sweet 12 inch letterbox is a complete letter box set with matching external and internal sections. It fits uPVC, composite and timber doors from 40mm to 70mm thick. The square edge suits doors where you want a clean, straight-edged look.

Choose from seven finishes: black, white, satin nickel, gold, rose gold, stainless steel and chrome. The body is metal alloy with a six-layer finish: five coatings, including brass and nickel layers, plus a physical vapour deposition (PVD – a hard, vacuum-applied top coat) layer on top. Check your door's cut-out against the sizes below before ordering.

Dimensions - Check It Fits:

Measure the width and height of the hole cut through your door, not the old plate. Fixing centres are measured from the centre of one fixing screw to the centre of the other.

This will not fit if: your door is thinner than 40mm or thicker than 70mm, or the existing hole is larger than the 314 x 70mm plate can cover.

• Fixing screw lengths: 45mm and 65mm (may need trimming to suit your door thickness)

All measurements are approximate.

What It Fits and Replaces:

• uPVC doors from 40mm to 70mm thick
• Composite doors from 40mm to 70mm thick
• Timber doors from 40mm to 70mm thick

Key Benefits:

• Corrosion-tested finish – tested for over 8,000 hours of saltwater exposure, which the manufacturer states is 30 times the industry standard. The finish is made to hold up on an exposed front door.
• 20-year anti-corrosion guarantee – backed by Ultion for 20 years against corrosion, once registered with the manufacturer within 28 days of installation.
• Double-sprung flap – a double spring at each end of the flap pulls it shut, helping keep draughts and rain out.
• Insulating inner skins – extra skins inside the set add sound and thermal insulation, so less noise and heat pass through the door letterbox.
• Fixed from the inside – the fixings are on the inside of the door and cannot be reached from outside. They screw into metal bosses, and the two screw lengths cover the full 40–70mm door range.

Pro Tips:

Pro Tip: Hold the outer and inner sections against the door and push a screw through before tightening anything. If the screw is too long for your door, trim it first so it pulls the two halves tight rather than bottoming out. This matters on a letter box for a wooden door, where thickness varies more than on uPVC.

Tools you'll need: A tape measure and a cross-head screwdriver. A junior hacksaw if the screws need trimming, and a jigsaw only if the existing cut-out has to be enlarged.

What's in the Pack:

• 1 × Letter box (external and internal sections)
• 2 × 45mm fixing screws
• 2 × 65mm fixing screws

Frequently Asked Questions:

Will this 12 inch letterbox fit my uPVC door?

Yes, if your door is 40–70mm thick and the hole is at least 262 x 46mm. As a letterbox for a uPVC door it covers holes up to the size of the 314 x 70mm plate. Measure the hole itself, not your old letter plate.

How do I measure for a replacement letter box?

Take the old plate off and measure the width and height of the hole through the door. Then measure the door thickness and the distance between the old fixing screws. This set needs a 262 x 46mm hole, a 40–70mm door and has 270mm fixing centres.

Can it be used as a letter box for a composite door or timber door?

Yes. It is made for uPVC, composite and timber doors from 40mm to 70mm thick. The same set is used on all three; only the screw length changes with door thickness.

How does the 20-year guarantee work?

The Ultion Sweet 12 inch letterbox carries a 20-year anti-corrosion guarantee from the manufacturer. You need to register your purchase with Ultion within 28 days of installation for it to apply.

Which screws do I use?

Use the 45mm screws on thinner doors and the 65mm screws on thicker ones. Either length may need trimming so the two halves pull together tightly.
