Safety equipment can also be hung on the eyelet Suitable to carry loads in the direction of the roofs fall line   Area of application   Most clay & concrete interlocking tiles & slates New build & refurbishment   Material   Galvanised steel 30x6mm; S 235 J2 G3C according to DIN EN 10025   Installation The Safety Hooks should be fixed in the centre of the rafter using the nails supplied. Minimum rafter cross section should be 50x80mm. The nails must be at least 25mm away from the rafter edge. If the safety hooks are not fixed directly to the rafters, but fixed through counterbattens or boarding, care must be taken to avoid the timber splitting on the account of its insufficient thickness. We recommend that when fixing the safety hooks into counterbattens or boarding, holes should be pre-drilled prior to nailing. To conform to Euro Code 5-1-1, fixings must be driven in to a minimum depth of 36mm into the load-bearing roof construction  (rafters). After any dynamic loading of a safety hook (occurrence of a safety critical event) the hook must be replaced, along with all the relevant fittings. Klobers installation instructions should be followed closely when fitting this product
