165cm Rustproof Zip Line Spring Brake

Length: 165 cm (5.4 feet); spring OD: 2.5 cm. Fully rustproof stainless steel body combined with dual 7 x 4 x 4 cm soft silicone buffer heads. Designed for consistent deceleration in outdoor zipline, aerial course, or material handling environments. The spring’s extended length allows deeper compression before reaching solid stop — smoothing transitions and minimising shock loading. Each unit undergoes visual and functional testing to confirm uniform coil spacing, smooth extension/recoil, and buffer plug adhesion strength. Installs in seconds by threading cable through both silicone ends — no tools, training or technical expertise required.
