CLD DULOK-8 SR1™ SPECIFICATION

Secured by Design accredited security fencing.

CLD DULOK-8 SR1 is certified to LPS 1175 SR1 Security Ratings. This means it’s guaranteed to stop any attacks from basic tools, and with Secured by Design accreditation from the UK Police, it provides the perfect perimeter for public buildings, schools and sports pitch applications.

Featuring a range of security enhancements that give this perimeter fencing an edge, adding immeasurable protection to your premises. These modifications make Dulok-8 SR1™ an even greater defence against criminals than our base Dulok™ system. 

Dulok-8 SR1™ mesh panels are made from twin, heavy-duty 8mm wires welded on either side of 6mm vertical wires, but rather than using pin hex screws, they are fixed to galvanised steel posts using Sheardrive security bolts; practically impossible for vandals and intruders to remove. 

You also have the option to include further deterrents to the top of each panel with Dulok-8 SR1™ being compatible with our Active Anti-Intruder topping range. 

FINISH

Our welded steel wire mesh fencing panels are hot dip galvanised only or galvanised and polyester powder-coated. The standard colour is Green RAL 6005. RAL range of colours available. 

PANEL DIMENSIONS

Heights – 1830, 2030, 2430, 3030mm 

Panel width – 2506mm 

Mesh size – 200 x 50mm 

Wire diameter – 6mm verticals 2 x 8mm horizontals 

Top edge projection – 30mm†

CLD DULOK-8 SR1™ POSTS AND CLAMPS 

For the Dulok-8 SR1 double wire panel system, CLD has developed a post and clamp bar system which provides a simple method of securing. Complete with an anti-vandal fastener, installed with either a battery-powered driver or traditional tools, this system offers a rapid and secure installation. 

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

The posts are available in a range of lengths to accommodate panel heights and ground conditions. In addition, many variations are available.

Toby E.
New side gate and panel fitted at the back garden. Good quality materials and the gate looks smashing.
Although it took a few weeks between accepting the quote and the work being done it was worth the wait. Used KF in the past and would do again.
MM S.
Absolutely delighted with this fencing installation. Most professional team came in and made a perfect job. My garden is now transformed! Many thanks to this superb company.
Sam K.
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!

Very pleased with the job. Very polite worker.

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.
