## Description

EXTENSION KITS THAT DO NOT REQUIRE A PROFESSIONALOur professionally prepared extension kits are suitable for both Voice and Data applications and will work with any service provider.We supply High Quality items that allows anyone to achieve a truly professional looking installation without paying extortionate prices. All of our kits use Genuine BT solid-core copper twisted pair CW1308 cable along with a mix of the other accessories needed.WHAT'S INCLUDED Genuine BT Solid Core Copper Twisted 2 Pair, 4 Core Cable A Pre-Wired plug to recreate socket & simplify your installation A BT2/3A Surface mountable Extension socket with screws 4 x 10mm Cable Protecting wall grommets for a tidy finish An IDC Inseretion Tool for inserting the cables as advised Enough Masonry cable clips to complete your installation Full colour Installation Instructions making things clearDo not be fooled by wild, misleading claims that the supply side of your broadband connection would benefit from the use of LAN cables such as CAT5, CAT5e and CAT6. CAT5 cables are supplied by others because of its cheap cost and also because of a lack of access to genuine BT cable.Broadband suppliers have spent years developing modems that have been optimised to use Solid Core Copper Twisted Pair Telephone Cable. Third-party modem suppliers have designed their devices to use this standard for all ADSL / ADSL2 and Fibre connections.Your Broadband Modem achieves its best possible results when there is some consistency on the supply side. Not a mix of cables with different specifications and intended uses.

Review: Amazing. Great instructions too! - Easy to install. High quality. No drop in speed/performance from the master socket to the extension. Really helpful instructions too. Thank you!
Review: Did what was needed - Used by my knowledgable friend, after I was switched to digital voice, to connect my centrally located DECT base station to the router, which was some rooms distant, by linking in to part of the previous internal phone wiring. It all worked fine, though not, if I understand correctly, the exact use it is made for.

## Features

- FOR BROADBAND OR PHONE – A professional grade kit that has been simplified by a Telephone Engineer in order to allow anyone with the need to run their own extension at a fraction of their service providers cost
- BEWARE OF FACTORY KITS - There is currently a surplus of imitation copper cables on the UK market. Many copies of BT CW1308 cables claim to be manufactured to BT spec but instead use either Copper Clad Steel (CCS) or Copper Clad Aluminum (CCA)
- PRE-WIRED DOUBLE PLUG – Your cable comes with a professionally fitted and tested main Telephone plug that creates 2 additional outlets and avoids the need for you to tamper with the master socket in your property
- WHY NOT USE LAN CABLE – Despite the claims you may hear, CAT5, CAT5e, CAT6 and now CAT7 cables should not be used on your incoming line as they were designed for LAN use. Local Area Network. ie. After Modem
- LONG LENGTHS POSSIBLE – We are able to supply these in long lengths only because we use cables with the same conductors as would be used by BT to serve a property down your own street for example. Same result.
