Alexandra Protek 656 Clamp Fencing

The Protek 656 clamp fencing has all the benefits of the 656 Double Wire panel system, but with the addition of a clamp fixing the panel to the post for increased security around industrial, commercial, retail and sports areas. This is a flat panel using twin horizontal wires 6mm in diameter, welded to a 5mm vertical wire. The panel is fixed to the post with a 40 x 5mm clamp bar.

Posts, Clips & Fixings

The posts and full length clamp bars that Alexandra offers, provide a fixing system which secures the panels but allows for variations. The system is easy to install, allowing the panels to be stepped, helping the fence line to follow the contours of the ground. With the vandal resistant security fixings this post and clamp system provides a higher level of security than the traditional clip system.
