The sidelock clip 456®-2 guarantees a high level of resistance against wind uplift loading. It was developed by FOS in response to benchmark changes in the national roofer’s regulation in Germany in 2011 specifically to improve the securing of tiles. It has become the most frequently used storm clip for professional fixing of tiles on pitched roofs in Germany and therefore plays an important role in day to day life of roofing contractors and carpenters.
In order to simplify the handling of the clip for roofers, FOS offers the 456®-2 collated on plastic strips. Each strip contains 25 clips and is suitable for the FOS ClipHOLSTER®. The collated clips allow for swift removal from its package. When mounting 456®-2 strips, the red protective cover cannot be used.
On the roof the use of the ClipHOLSTER accelerates the installation considerably. Because the ClipHOLSTER is fastened to the belt, the clips are within easy reach. The roofer has his hands free and can therefore work more efficiently. In practical tests, time savings of up to 25 % were recorded.
The 456®-2 is mounted onto the batten from the back. A special notch on the clip guarantees a secure hold on the batten at all times. The hook of the clip is placed in the outer sidelock of the roof tile. The clip holds three tiles in the four-tile corner. The optimised shape prevents the elongation of the clip under load.
Single roof tiles secured with the 456®-2 can be replaced quickly and easily if damaged by weather or age.
Stainless steel in 1.4301 (A2) quality or ZIAL® (zinc aluminium) coated surfaces guarantee the sidelock clip’s long-lasting durability. The clip is available in various types for a wide range of roof tiles and with a round and an angular hook.
