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.

Protek 656 Clamp Specification

Fixing

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.

Options

  • Panels can be inverted to create flat top option
  • Other heights available on request

Product and Finish Standards

  • Mesh panel wire manufactured to BS 4102 and galvanised to BS EN 10244-2:2001 class D, weld strength is 75% of the minimum tensile strength of the wire (tensile range 540-690 N/m2)
  • Post material manufactured to BS EN 10210-2:1997 and galvanised to BS EN 10346:2009
  • Panels & Posts are powder coated to BS EN 13438:2005 (min 100 micron)

shaun C.
This is the 3rd time we have used Knight Fencing Ltd and I can’t recommend them highly enough.A quality product built by a courteus team.
Laura S.
Terry from Knight Fencing completed a 22m 6ft high fence and gate installation for us in April 25. From the initial quote Terry went above and beyond to suggest clever solutions to how we wanted the fence put in, eventually helping us to settle on a trellis to keep the view from the end of the garden. When completing the work he and Sam arrived promptly and worked so hard all day to get the work done. They have done an incredibly professional job, the fencing looks fantastic and they left the garden, if anything, tidier than it was before they arrived! I would highly recommend them and thank you for doing such a great job, we can now enjoy the garden without worrying about our dogs escaping!
Theresa B.

I couldn’t be happier with my new fence! From start to finish, the team was professional, efficient, and attentive to every detail. They offered expert advice on the best materials and design for my property, and the installation was seamless. The quality of the craftsmanship is outstanding, and it has truly transformed the look of my garden. I highly recommend this company to anyone looking for reliable, high-quality fencing. Excellent service and amazing results!
