The vertical letterplate Jubilee mailbox.
This letterbox uses a vertical conventional and discrete letter plate but still has the same large capacity as our other post boxes. Your mail is delivered through the wall via a heavy duty chute attached to a traditional style letter plate and contained in a sealed storage box with a rear lockable access door.

Designed to be fitted through:

  • Single brick walls
  • Double or cavity brick walls
  • Brick piers.

When built into a 2 brick pier (or larger), the mail is securely stored within the cavity area allowing both the front letterplate and back casting to fit flush against the brickwork or rendering.

  • Extremely secure design
  • Standard size has ample capacity for all your mail and newspapers
  • Customised case sizes available to fit any depth wall or pier up to 1000mm
  • Choice of polished brass, chrome, brushed chrome or textured black letter plates
  • Supplied complete with 2 keys

LS14 Letterbox Dimensions

The Jubilee mailbox is designed to be installed into brick walls or brick piers up to 1000mm thick. The dimensions of all the fittings are shown below.

Shown below are the dimensions of all the Jubilee postbox models. Dimensions are in mm

Letter plate

These are the dimensions of the post flap supplied with the LS14. This post flap is shown in textured black but is also available in brass and polished or brushed chrome.

  • A = 305mm, the overall height of the letterplate.
  • B = 96mm, this dimension is the overall width of the letterplate.
  • C = 57mm, the width of the letterplate orifice.
  • D = 233mm, the height of the letterplate orifice

Single wall and brick piers chute assembly

The single wall chute dimensions are shown below, the chute can accommodate wall thicknesses between 100mm and 112mm. The postflap above is not shown fitted, but when assembled it is attached to the front of the sleeve. This sleeve is used for all depths.

  • H = 248mm, the overall height of the sleeve, the hole in the brickwork would need to be approximately 82mm.
  • W = 78mm, this dimension is the overall width of the chute, the hole in the brickwork should be around 252mm.

Collection Box

The collection is located within the cavity area when fitted into a brick wall or pier, for a double or cavity wall the box is located at the rear.

  • A = 250mm, the height of the opening for a single wall depth chute.
  • B = 80mm, the width of the opening.
  • D = 242mm, the overall depth of the standard size collection box, used for single, double or cavity brick walls. See below for details of sizes for cases to fit deeper walls or piers.
  • H = 425mm, the overall height of the collection box.
  • W = 295mm, this dimension is the overall width of the collection box.
  • X = 123mm, the distance from the bottom of the letterbox casting to the bottom of the letter opening
Stamford postbox sleeve dimensions

Collection Box Sleeve

Shown below are the dimensions of the inner sleeve of the standard size collection box.

  • A = 402mm, the distance between the bottom face of the sleeve and the top of the apex, the overall height of the letterbox sleeve is taller as the sides extend below the bottom by 13mm making a total depth of 425mm. These extensions to the sides are generally bedded into the mortar when being built into a brick wall or pier.
  • B = 383mm, the distance between the bottom of the sleeve to the top of the side before the apex begins. The apex of the sleeve rises 20mm from the side to the peak in the centre.
  • C = 397mm, the dimension of the side of the sleeve from the very bottom to the lower point of the top apex.
  • D = 230mm, the depth of the standard size sleeve. See below for details of sizes for cases to fit deeper walls or piers.
  • E = 275mm, this is the width of the sleeve.
  • F = 13mm, this dimension is the distance between the bottom of the sides and the floor of the mailbox sleeve.
Dimensions of the LS05 Postbox Retrieval Door

 

Rear Access Door

Below are the dimensions of the rear access door of the LS10 Stamford rear retrieval postbox.

  • A = 180mm, this is the width of the rear retrieval doorway
  • B = 185mm, this is the height of the rear door entrance

The diagonal distance of the letterbox opening is 257mm, easily big enough to remove A4 or large packages. A telephone directory sized package can be removed from the letterbox without needing to be bent in any way.

Sleeves for deeper walls

The standard case size is designed for single, double or cavity walls and 1½ brick* walls or piers. In addition we have standard size cases for 2, 2½ and 3 brick* walls. For other depth walls or piers we will need to manufacture a sleeve to suit. To make the correct size we require two dimensions as shown below. 

  • A, the thickness of the brick (this is 102mm for a standard metric brick).
  • B, the overall depth of the wall or pier from the outside faces.

* Based on a standard metric brick (215mm)

 


LS14 Jubilee fixing instructions

1) Cut a hole all the way through the front face of the brick wall (or if building a pier, the outer front face). 80mm wide x 250mm tall. Cut a notch each side of the outer face approx. 20mm high x 15mm deep. This is to give clearance for the two nuts on the rear of the letter plate.

Take a note on how the letterbox is assembled. Now undo the four brass nuts on the back with the 4mm key supplied. Remove the back casting, unscrew the four M6 threaded studs. Replace the brass nuts including the nylon washers onto the studs. Put them safely to one side, as these will be required again on final assembly.

The letter chute is bolted to the rear of the front casting for transportation. Undo the two 6mm bolts and nuts, these are not required and can be discarded.

Using the two grub screws and nyloc nuts provided attach the letter plate to the chute. Making sure the hinge is at the top. DO NOT OVERTIGHTEN THE SCREWS.

Note the orientation of the tensioning angle brackets, as they will be replaced the same way later. Remove the six button head screws from the chute using the 2.5mm hex key. Put the screws aside for later re-use. It is not  necessary to remove the grub screws.

From the front of the wall/pier, get an assistant to push the chute through the hole until the letter plate butts up to the front face of the brickwork. Remain holding in place.
From inside the wall/pier, position the back plate over the chute and mark the three securing fixing hole positions. Remove the back plate and drill three 8mm holes. Do not screw the back plate to the wall yet.
On the wall side of the back plate put a generous bead of clear silicon, about 20mm in from the outer edges of the top, left and right-hand sides. (NOT THE BOTTOM EDGE) Also place a bead of silicon all around the chute hole about 5mm from the edge.

Locate the back plate over the chute and push firmly against the wall. Now secure with the three wood screws provided

Run a small bead of clear silicon around the top and side joints of the chute and back plate. Smooth off with a wetted finger to ensure a neat watertight seal.

Replace the tensioning angle brackets onto the chute using the six button head screws.

Using the 3mm hex key, tighten the 4 grub screws up against the casting to tension the letter plate against the front face of the wall/pier. (DO NOT OVER TIGHTEN). Now run a small bead of silicon around the outer edges of the letter plate and brickwork.

Next step is to re-assemble the case and rear casting. Ensure that the neoprene channel seals are positioned around the edges of the case. Re-assemble the rear casting and case onto the front casting using the four long threaded studs, brass nuts and nylon washers.

 

LS14 Jubilee fixing instructions for a 2 brick pier

 

  • A   Width of shaved brick, between 80 and 82½mm (Based on a 445mm wide pier)
  • B   Width of gap to accommodate box, minimum 280mm
  • W   Width of a typical 2 brick pier, 445mm
  • X   Width of notch to accommodate front casting, 9mm
  • Y   Depth of notch to accommodate front casting, 11mm

In order to fit into a standard 2 brick pier, the bricks on the left and right hand sides need to be shaved back to leave a central gap between 280 and 285mm.

Based on a standard 2 brick pier which is approximately 445mm wide, the outer bricks would need to be cut down to a maximum of 82½mm and a minimum of 80mm.

There also needs to be a notch cut on either side at the front to accommodate the front casting.
