We're launching in the UK with 3 sizes of clips initially to fit twin and earth cables: 1.0/1.5mm², 2.5mm² and 4.0/6.0mm².

ViperClips are available in standard and fire clips. The fire clips can be used to prevent the cables collapsing prematurely in the event of a fire. You can fire both from the ViperClip gun and change between clip types as easily as change the clip size.

ViperClip products have been designed for use on wood - both natural timber and engineered wood (hardboard, osb and ply). Whilst they will work on engineered block and some breeze block and plaster, it will depend on how hard and dense the material is.

Yes, ViperClip fire clips will do this job perfectly with metal nails and a steel bridge. These clips will prevent premature collapse of cables in a fire. Full details of our fire clip tests are available in our Technical section.

Yes. We will be bringing out clips for other markets where the flat twin and earth cables are a different size from the UK e,g. Ireland, Australia and New Zealand.

We'll also have clips to suit the NM cable such as Romex in the USA and Canada and the round lighting and outlet cables across Europe.

The ViperClip gun is unique in that we use the clips with the gun to create the cable guide. By using the correct sized clip for your cable, and by selecting the front guide according to your cable, the ViperClip fastening solution will centre your cable right along the centre of the gun, ensuring the nails fire perfectly on either side of the cable. Simply place the gun over the cable, ensuring it's flat against the surface and fire!

No. Our gun and battery have a battery management system which optimises safety and product performance and should only ViperClip batteries used on ViperClip guns.

Our safety mechanism on this gun is set to activate with the smallest cables size - the 1.0mm². If your cable is too small, then it is likely the safety won't engage and the gun won't fire.

If you have a requirement for use with a smaller cable, please contact us.

In tests we've found the battery life to be good at well over 1000 fires per full charge.
