4. 1STec

Black, 1STec 20m of Genuine BT CW1308 4 Core 2 Twisted Pair Telephone or FTTC Broadband Extension Wire + 4 Grommets + IDC Insertion Tool + 4mm Clips + Printed Colour Code Instructions 20 Metre

1STec - Beware of cheap imported versions - there is currently a surplus of imitation copper cables on the UK market. These cables have either of the two standard BT / BCC colour codes and are guaranteed to be made of copper so that you get the best possible performance from the network.

They are compatible with bt infinity, Sky, EE, Plusnet, Virgin Telephone, TalkTalk and many other Internet Service Providers. Achieve a professional looking installation at the fraction of your suppliers price. Avoid slow broadband + a quiet phone - using the incorrect cable can have a dramatic effect on Router speeds and even the volume on your Telephone line. Ccs and cca versions also introduce many connectivity problems associated with corrosion and oxidation. Genuine bt openreach copper cable - manufactured in the uk to the very highest standards.

Includes installation accessories - all lengths are supplied with an IDC insertion tool, 2 cable protecting drill hole grommets, full colour code installation instructions and matching cable clips. Many copies of bt cw1308 cables claim to be manufactured to BT spec but instead use either Copper Clad Steel CCS or Copper Clad Aluminium CCA. Telephone and superfast broadband - these cables are perfect for extending both Telephone and Broadband signals around the home.

7. 1STec

1STec 25 x Genuine BT 3 Wire 8B External Internal Waterproof Gel Filled Crimp Connectors for Joining Solid Core Telephone or Alarm Cable Connecting Block Repairs Splice or Join Phone Wires 25 Pack

1STec - These provide a waterproof connection, Virgin Media and independent contractors. Genuine openreach crimps - gel filled crimps as used by BT, repair or splice telephone wire. Superior gel properties - only the genuine bt clear connectors will protect IDC contacts from the oxidative effects of moisture in the long run.

Correct connection - once the lid is closed squarely a connection is made. 2 / 3 wire options available - both versions provide a reliable means of connecting PE or PVC insulated copper or aluminium Telephone conductors without the need to strip the core insulation. Try using your hands - it is possible to close these by hand by pressing them firmly from the back up against any flat surface. If you do decide to use standard pliers you will need to work your way around the connector top ensuring that it is evenly closed.

Used to connect, are simple to use and are recognised as original equipment. It is better to avoid standard pliers as these close the connectors at an angle due to the non-parallel action of the jaws. Most of the imitation multi coloured, non industry standard connectors are filled with inferior Vaseline. Simply insert the matching colours and press the cap shut. An angled lid prevents even wire contact.

1STec - 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.

Same result. Genuine openreach cable – we only use the latest bt openreach cable with the new colour codes pictured. 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. Internal / external use– kits available with either black uv protected CW1308 cable for outdoor use or white cable that can be clipped to wood or masonry for indoor installations.

The older colour codes have been heavily copied and most are not copper cores even though they say so. 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.
