• LINQ - Height Safety Standards

HEIGHT SAFETY STANDARDS

All LINQ harnesses and lanyards are independently tested and certified by SAI Global in accordance with Australian and New Zealand Standard AS/NZS 1891.1 2007.

Whereas some brands will ‘self-certify’ or claim to use a third party assurance program, LINQ Height Safety invests in the most respected and much stricter SAI Global Certification process and Quality Assurance Program.

Independent auditing of LINQ products by SAI Global ensures retailers, HSE officers and end users can have the utmost confidence that LINQ harnesses and lanyards meet or exceed the protection as required by Australian Standards. In fact, LINQ internal QC specifications require the product’s performance to exceed AS/NZS standards in some cases by as much as 400%.

SAI Certification is displayed in the form of the SAI Global Standards Mark™ or “5 Ticks” logo representing reliability, quality assurance and safety – hallmarks of all LINQ Height Safety Gear, along with comfort, performance and affordable pricing.
