The isostatic conception of the clip permits the dilation and retraction of the wooden boards without damaging the wood or the clips. The clips’ resistance, tested by the FCBA, is 1.5 to 2.5 times stronger than required by the DTU 51-4 norms.
It’s just as easy to remove the boards as it is to attach them, thanks to our special removal keys. All it takes is sliding the keys between two boards and unsnapping the clips from the rails. The boards, clips and rails are still in perfect condition to be easily repositioned as needed.
Decking and cladding in a snap!
Grad® technology combined with quality materials for decking and cladding with 100% invisible fastening.
A unique and patented concept.
On any type of decking or cladding, Grad® keys allow the removal of one or several boards in order to access the supports. The clips, left on the board after removal, are removed by simply sliding them off to be fixed again at the original place on the rail.
