Shockles™ LineSnubber™, Shock Absorber for Dock Line Blue, 20" (51 cm) - SKU 2400Progressive tension design means the further LineSnubber stretches, the greater its return force. The result is smooth action and moderated stress. The patented internal line limiter is made of 2500 lb. (1140 kg) test nylon webbing. LineSnubbers outer sheath is 3500 lb. (1590 kg) test tubular nylon webbing that is UV resistant to protect internal parts. Shockles are strong, but they need to be rigged in line so they never bear the full load alone. Six
