CLD ULTIMATE EXTRA SR1™ SPECIFICATION 

There are premises where only the highest levels of security will suffice. Places like Ministry of Defence buildings, police stations and airports, where you need guarantees that your fencing is up to the task. It’s these locations that Ultimate Extra SR1™ was designed for. 

As the highest security profiled panel system in our Ultimate™ range, Ultimate Extra SR1™ includes many enhanced security features, including durable 6mm diameter wires, projecting spikes at the top of each panel, large steel posts, a full length clamp bar, plus revolutionary built-in SafeTfix security fixings that are totally enclosed. 

Conforming to BS 1722-14 for open mesh steel panel fences and carrying certification to Loss Prevention Standards 1175 Security Ratings (SR1), it will withstand attacks from standard hand tools. Plus, as an added seal of approval, Ultimate Extra SR1™ comes with the UK Police Secured by Design accreditation as an effective form of crime prevention. 

FINISH

Our welded steel wire mesh high security fencing panels are galvanised and polyester powder-coated after stringent cleaning and treatment to give a well-adhered coating of 60 microns. RAL range of colours available.

Heights – 2030, 2430, 3030mm 

Panel width – 2475mm 2050mm (3030mm) 

Mesh size – 165 x 25mm 

Wire diameter – 6mm

Triangular folds – 3 or 4

CLD ULTIMATE EXTRA SR1™ POSTS AND CLAMPS 

For the Ultimate Extra SR1 profiled panel system, CLD offers a standard post and clamp system which provides a complete method of securing, allowing infinitely variable stepping of panels within the post length. It is versatile, strong, simple to fix and vandal resistant, yet allows panels to be removed without damage to either post or clamp. Accidentally damaged panels can be replaced without removing the post. 

SLOPING GROUND

Panels can be stepped as required. Where gradients exceed 1:16, it is recommended that taller panels are either part-buried or additional posts are used. 

VARIATIONS

In addition to the standard posts many variations are available to accommodate site requirements.

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.
Mark H.
A massive mention for Jade who throughout the process of my purchasing and having installed two new large rear gates has been exemplary, customer service should be taught at retail outlets by this young lady. Thank you and the gates look great.
Alastair H.
Great job on my fencing and gates from Knight fencing. Five star service.
flora L.

GREAT FENCING!!! We asked Knight Fencing to run 4ft 6"double closeboard with 18" close diamond trellis around our last property (in Bedhampton). This was because we saw what a great job they had done at one of our friend's gardens (in Southbourne). Then another friend saw what we had installed and Knight Fencing did the same for them at 6ft 6" around 3 sides of their back garden (also in Bedhampton). We then had the bottom of our garden re-fenced with 6ft 6" double closeboard when we first moved into our new property (in Purbrook). We are now ready to have the rest of the garden re-fenced and have no hesitation to call Knight Fencing again. Any time anyone has seen these 4 fencing jobs they only say what strong, professional and quality fencing it is.
Matt C.
efficient, helpful, accommodating, friendly and a high standard of work.
