Super-7 Thor-Helical Nail for Pitched Roof
Product Description
Super-7 nails install flush to the counterbatten. They are manufactured from stainless steel and are engineered with the precise Thor-Helical patented helix, and so provide maximum corrosion resistance and excellent holding power. They are stocked in six standard lengths and meet the technical requirements of the NHBC.
The Super-7 Alignment Tool is an innovative tool that vertically aligns and centres a nail on the counterbatten to rafter arrangement, improving build quality.
HeliCalc is a free web-based program available at www.heliclac.co.uk . Users simply input details of their site location and roof construction, and HeliCalc calculates the length, density and quantity of Super-7 nails required for the project.
Stocked Lengths: 140, 150, 160, 165, 175, 185mm
Other lengths are available in increments of 5mm.
