The classic 409®, which has proven its worth millions of times over, has been optimised in terms of its design and stored in a magazine; the further development is being sold under the name 409®-2.
The 409®-2 clips are delivered on plastic magazine strips. Every strip holds 25 clips and is suitable for the mobile FOS ClipHOLSTER®. The magazine clip storage enables swift individual clip removal. The red protective cover reduces the risk of injury as well.
On the roof, the new magazine storage simplifies installation the clips, the proximity of the holster handle makes the process considerably quicker. In practice tests, up to 25 % time savings were achieved during mounting of the 409®-2 together with the ClipHOLSTER. Empty magazine strips can be replaced quickly and conveniently.
The design of the previous model has been optimised in a number of ways. The FOS quality seal can be found on the clip’s hook. Even after decades, the imprinting of the logo provides proof that you are using a high-quality brand product.
To simplify hammering in of the clip, in the case of the round 409®-2, the round hook enables lateral turning away from the side lock. In the case of the angular 409®-2, an angle produces this effect with an offset of approximately 1 cm from the side lock.
Unlike the 409®, the 409®-2 is available in five different tip lengths as opposed to four: 42 mm, 52 mm, 62 mm, 72 mm and 82 mm. This results in a better ratio between the tip length and the penetration depth in the batten and therefore between the tip length and the roof tile. All of the roof tiles’ assignments to the new lengths were checked and specified. With the FOS ClipCHECK product finder, they can be quickly determined by specifying the area of application, the installation type, the roof tile and the batten.
On the impact tip, an additional collar clearly indicates the minimum depth to which the clip must be hammered in. The new embossed grooved section on the impact tip increases the clip’s pull-out resistance from the wood.
