Lochrin Defender SL3 is an innovative high security palisade fencing system designed and developed by Lochrin Bain.

After undergoing independent attack tests by BRE the patent-pending design entered into the RED BOOK successfully achieving LPS1175 SR3 rating. The unique construction has been designed to ensure a minimum delay time of at least five minutes, independently tested to defeat a range of attack methods including both hand tools and power tools.

This fencing system is ideal for protecting assets on sites including water utility sites, oil and gas compounds, data centre and other sites of critical national importance.

About LPS 1175

LPS 1175 is the requirements and testing procedures for LPCB approval. ‘LPS’ stands for ‘Loss Prevention Standard’ and LPS 1175 is one of many standards by the LPCB ‘Loss Prevention Certificate Board.’

The LPS 1175 standard focuses on physical security including security fencing, with ratings split into 8 different security ratings (SR Levels) with test requirements of ascending intensity. These are measured in terms of attack tools and also time available to the attacker.

Once tested and approved, SR rated products are entered into the LPCB redbook, which is a key reference for specifiers, regulators, designers and end users to select products according to the risks that they and their property face.
