LINQ® TETHA BLOQ 2m Self-Retracting Lifeline (Inertia Reel) with Triple Action Karabiners

The LINQ® TETHA BLOQ 2m Self-Retracting Lifeline (SRL), also known as an Inertia Reel, is a premium compact fall arrest device designed to provide maximum safety and unrestricted movement when working at height. Constructed with 25mm Technora® (Aramid) webbing housed inside a high-impact UV-resistant transparent polycarbonate casing, the TETHA BLOQ automatically extends and retracts to maintain constant tension, reducing slack, minimising trip hazards and significantly limiting free-fall distance. Available with three connector configurations – KTSD, KTST and KTKT – the TETHA BLOQ can be selected to suit a wide range of work-at-height applications across construction, mining, utilities, warehousing and industrial maintenance.

Designed for harsh Australian worksites, the TETHA BLOQ features dual stainless steel guide rollers to minimise webbing wear, a swivel top anchorage to reduce twisting during use and an integrated energy absorber that limits arrest forces to less than 6kN. The transparent housing allows quick pre-use inspection of the internal webbing and components, while the unit is rated for users up to 140kg (including tools). Whether fitted with scaffold hooks or triple action karabiners, the TETHA BLOQ delivers lightweight, durable and dependable fall protection for professionals working at height every day.
