Since there are a vast number of different types of roofing tiles with different properties, we’ve designed just one roof hook that fits for all of them.
The height adjustability in the arm of the hook, the ability to shift the arm left, right or centre and the smaller fixing holes in the base plate, all help to ease domestic installations with the use of just one type of roof hook.
As well as making the fixing holes smaller to accommodate smaller rafter widths, we’ve also offset these from each other within the base plate. This is so the pressure of the system isn’t focused on the screws in the same line and therefore, protects the rafter. We also take care within our designs, to further offset the roof hooks from each other to help distribute the weight of the system evenly across the roof and in doing so, avoids heavy point loading.
We’re fully in support of the MCS 012 certification requirement on pitched roof mounting systems, which came into force in 2014 and since then, we’ve followed every significant step to comply and give substance to the scheme.
Module clamps, mounting rail, roof hook and fixing screws.
These are the only components that you need to fit this system and what’s more, we’ve even pre-assembled the roof hook so that it’s already prepared for connection to the mounting rail. This dramatically reduces the installation time and keeps you on schedule.
