Geometry and security standards

The 120 cm long lasso chain with Ø 10.5 mm case-hardened steel square links offers an optimal compromise between relative lightness (3.75 kg) and protection level. The integrated padlock measuring 74 x 112 mm features a reversible Ø 14 mm hardened steel shackle, guaranteeing exceptional resistance to cutting or twisting attacks. The system benefits from an anti-corrosion passivation treatment and a black woven textile sleeve that prevents any direct contact between the steel and the vehicle.

AUVRAY technology and design

AUVRAY Security, a French brand founded in 1982 and based in Bourg-de-Péage (Drôme), has been developing SRA and ART certified high-security anti-theft devices for motorcycles, scooters and bicycles for over 40 years. The K-BLOC 120 ART incorporates the latest protection technologies:

• Reinforced case-hardened steel: surface heat treatment that hardens the links by increasing their carbon content, making cutting extremely difficult
• Dual locking mechanism #1: patented AUVRAY system with anti-picking disc cylinder and shackle anti-rotation device
• Reversible key lock: dual profile for easier insertion and increased drilling resistance
• Weather resistance: waterproof design and anti-moisture cover for optimal operation even in extreme conditions (cold, rain, frost)

Kit contents and use

The kit is delivered complete with 1 lasso chain 120 cm Ø 10.5 mm, 1 high-security padlock 74 x 112 mm with Ø 14 mm shackle and 2 reversible keys. The padlock can be used independently from the chain as a mini-U or backup lock. The 120 cm length allows easy attachment of the bicycle or motorcycle to a post, hoop or solid fixed point, while securing the frame and one wheel. For enhanced protection, AUVRAY recommends combining this kit with a floor or wall anchor ring.
