425 beaver tail clip to mount on

Rainer Schledt from Münster in Germany sums up the new 425 beaver tail clip as follows: “Practical, handy, effective, inexpensive and time-saving.” He was one of the product testers who had the chance to test and rate the 425 as part of FOS’ heroes campaign.

We offer our 425 in different sizes with the usual stainless steel and ZIAL® finishes. The new beaver tail clip convinces through its excellent value for money besides our “Made-in-Germany” quality. Clip-beaver allocation can be determined using our clip allocator ClipCHECK.
