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)

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.
katrina M.
Wonderful job these guys did - Daniel & Liam the installers were professional, polite and advised what the process was going to be.

We recently bought the Hutton Six Seater Round Picnic Table from Knight Fencing and are really pleased with it. It's sturdy, good-looking, and feels like it's built to last. Assembling it took about an hour, but the instructions were super easy to follow.

We had one small hiccup - we cross-threaded a bolt by mistake. But, it wasn't a problem as they'd included some spare parts in the pack, so we sorted it out quickly.

If you're near Sidlesham, do swing by their display area. It's full of tough garden furniture, different types of fences and gates - worth a look. Plus, if you're in the PO postcode area, delivery is free.

All in all, I can definitely recommend Knight Fencing and their Hutton picnic table. It's a good buy and they're excellent to deal with :)

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.
Marion S.
Very pleased with the service from Knight Fencing. From the visit
to see property and receiving my quote, to the work carried out
both men very polite and experienced . All work excellent.
Clare H.
We went by the reviews because we're new to the area and had no personal recommendations. The reviews are absolutely spot on. Very efficient, staff are great, the fence is brilliant, they left everything neat and tidy. Highly recommend.
Ann J.
We are extremely pleased with the service and the results
