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)

Simon O.
Knights came highly recommended and didn't disappoint - a first rate job at a fair price. Many thanks

We had to replace our garden fencing and gate recently. Having looked at a few fencing companies and the reviews they had received, we chose Knight Fencing Ltd. It was an easy decision, from the moment we originally contacted them to discuss our requirements to completion of the works. Their professionalism throughout was excellent. There were many obstacles to overcome and these were considered and undertaken with no fuss. Whilst we had already chosen to use Jackson Fencing products, Knight Fencing arranged everything with them. The installation team were very professional, polite and considerate. We have no hesitation in recommending Knight Fencing Ltd.
Rik N.
Alex and Jason did a great job for us. Very pleased with the result.
They also dealt with attention from the neighbours very diplomatically.
Would deffo deal again !
Barbara P.
Knight Fencing fitted new gate posts and fencing around the front of our property. Excellent standard of work and the guys worked so hard in appalling weather conditions. Very impressed.
Graeme F.
Terry and Sam have done some really fabulous work for us. Totally reliable and give a full service experience for the customer. Will always go the extra mile to make sure the job is just right.
Sam C.
Brilliant service and great quality. Will be using them again as required.
Deborah O.
We had a new gate installed and our double security gates made higher.

The workman were friendly, efficient and the work was carried out to a high standard.

We would highly recommend knight Fencing

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!
Mike L.
Very pleased with the service provided. The delivery was on time and the quality of the item was very good. I did have one damaged panel and when I raised the issue, they immediately arranged for a replacement panel to be sent. I dealt with Jade Wallace throughout the ordering and delivery process and she was excellent, keeping me informed and providing top notch customer service.
Ruth C.
Very pleased with the job. Very polite worker.
