The amazingly adaptable Sheffield design is a built-in style post box. This item has been handcrafted from a combination of solid cast aluminium and thick, high-quality steel. The inner compartment consists of two sheets of steel, which can extend another 8cm. A competent, DIY person could drill the inner casing and extend it further if necessary. Telescopic post are more expensive to buy and fit than a fold down, hinged or removable driveway security post. They can be fitted to old or new driveways as the block paving can be re-laid snugly around the post hole once installation is complete.
Telescopic through the wall post boxes are extendable and are ideal for projects where the property wall dimensions are not currently known. Fixed dimension through the wall post boxes are ideal for projects where the wall depth is known, offering a combination of cost-effective pricing and easy installation.
Through the Wall post boxes are typically manufactured using high quality zintec steel and aluminium extrusion or brushed stainless steel. Mailboxes are available in a variety of colour finishes to meet the design style of each project and location, finished with polyester powder coated paint from our standard range of RAL colours.

How are through the wall mailboxes installed?
An aperture in the installation wall should be prepared prior to the installation of mailboxes – dimensions can be supplied on request to suit each bank of mailboxes. An 8mm gap should be catered for around the bank of mailboxes to allow for easy installation.
The mailboxes should be placed into the cutout aperture and then screwfixed around the edges of the boxes to the wall.
When using through the wall mailboxes, are support lintels required?
Yes.
We recommend that a support lintel is fixed directly above the opening aperture that the mailboxes will be installed into. A support lintel will help to ensure that the weight of the property wall is distributed away from the mailboxes.

The TeleSpar® sign support system does more – and does it better – than anything else in its class. You simply won’t find better performance at any price. Yet, no other product makes available dollars work so hard or go so far.
The reason is simple. The TeleSpar® system was engineered specifically for sign support use, then perfected with the help of traffic-control professionals. In short, we listen. That’s the reason TeleSpar® has become the most complete, cost-effective and easiest-to-use sign support system in North American.
A Complete System
The TeleSpar® system consists of square, perforated, welded steel tubing, in eight sizes and three gauges. Perforations or knockouts on all four sides allow you to mount signs back-to-back and on adjacent sides.
The unique manufacturing method used to produce TeleSpar® tubing permits tubular sections of different sizes to telescope into the next larger size making adjustment, reinforcement and splicing fast and easy. The square shape also provides superior windload capacities and torsional stability.
TeleSpar® tubing is complemented by a variety of compatible fittings, accessories, nuts and bolts, and simple installation tools, creating an engineering system of integrated parts.
THE TeleSpar® SYSTEM IS BACKED BY NATIONWIDE DISTRIBUTION. With TeleSpar® tubing, you get the benefit of our distribution system, through our sister company Unistrut Distribution, which extends throughout the U.S. and Canada.
Large inventories ensure that multiple sizes of TeleSpar® tubing are in stock. Local distribution points can provide for immediate orders and prompt delivery. Large orders are sent directly from the factory, thereby avoiding warehouse costs.
Ground Support Options
Single Breakaway Anchor: using either manual or power equipment, a minimum 30″ section of 12 gauge TeleSpar® tubing is driven into the soil to serve as an anchor base. 1″ to 2″ is left exposed above the surface. One man working at ground level can safely and easily insert a 14 gauge signpost into the anchor base and bolt it in place. Installation time is thus kept to a minimum. Signs can be bolted onto the post before installation.
Two-Piece Breakaway Anchor: a two-piece breakaway system is easily created by adding a 12 gauge outer sleeve of the next larger size tube to the original anchor base. This additional sleeve, approximately 18″ long, provides a double wall thickness to accomplish the breakaway function. When installing in soil, it is advisable to drive the anchor base and outer sleeve together, leaving 1″ to 2″ of the assembly exposed above the surface. The signpost is then inserted and bolted into the anchor assembly.

FHWA Approved System Installation
Single Breakaway Anchor: A single breakaway anchor system allows work crews to perform around installations and rapid replacement of signposts after vehicle impact. When installing the system, the anchor should be one size larger than the signpost and driven using an appropriate size drive cap. All anchors should be driven into the ground leaving 1 to 2 holes exposed for signpost connection.
Two Piece Breakaway Anchor: High impact installations require constant replacement of damaged posts and anchors. An additional 18″ outer sleeve, one size larger than the anchor is used to double the anchor wall thickness at the critical bending area. This system will provide quick replacement of damaged signposts without the need to reinstall a new anchor into the ground.
Direct Embedded: Signposts can be driven directly into the ground without anchoring sections, using a drive cap with sledge or power equipment.
Note: All anchors should be 12 gauge TeleSpar® tubing.
