425 beaver tail clip to mount on

Beaver tail clip 425 secures crown and double coverings, besides that all beavers with tower beavers. Replacement of individual beaver is made possible by flexibility achieved through new clip form and laying pattern.

The handy form of 425 prevents interlocking of clips one beneath another and facilitates tool-free installation. The right position is automatically achieved through optimised clip focus.

Smaller pack sizes and light weight enable ease of use at the roof and warehouse. Each package contains 500 units capable of fixing an average roof area of up to 22 m2.

The storm clips are installed in rows contrary to the known diagonally arranged laying pattern. This results in higher wind uplift resistance and simplifies the laying process.

Fixing time for 425 is reduced significantly through its handy form, tool-free installation and effective row format laying pattern.

425 are available in stainless steel or ZIAL® and in various sizes suitable for diverse beaver thicknesses and batten depths. The product locator FOS ClipCHECK® determines the perfect clip by entering the area of application, the type of mounting, the beaver and the batten.
