Kingsmill Slate Holdfasts are used for the installation of circular or flat lightning protection conductor above the roof tiles without the need for drilling holes.
Material: Polypropylene clip/Aluminium tape
Standard: Aluminium tape to BS:EN 755-5
The aluminium tail slides under the roof tile and is fixed to the wooden beam or tile batten using proprietary galvanised nails. The clip then protrudes from the tile and offers a fixing for the conductor.
When choosing a connector it is important to ensure:
- The connector is mechanically robust.
- The connector is selected according to its application.
- The connector is rated for its application.
- To avoid bimetallic corrosion: use a bimetallic connector (do not connect bare copper directly to bare aluminium, or have water run-off from copper fall onto aluminium).
