Product Description

Rock-N-Rescue and New England Ropes have teamed up to produce an exceptional static rope for rappelling, caving, rescue, fixed-rope applications, hauling, and life-safety applications. R-N-R Lifeline’s unique polyester sheath differentiates it from other static ropes. The polyester sheath is balanced with a nylon core to limit rotation, bouncing, and stretch with exceptional UV resistance. Poseidon Series Lifeline is NFPA and CE approved, and comes with an NFPA certification tag and CE labels. This is one of the most durable static ropes available with the handling and knotability you expect from Rock-N-Rescue. The sheath of the rope is made with a 32 carrier sheath design. 32 carriers provide a middle ground between a stiffer, durable 16 carrier design but is harder to work with and a 48 carrier design that is softer and easier to work with but is not as durable. R-N-R Lifeline combines the better characteristics of both which allows for an incredibly smooth sheath, higher tensile strengths, and superior handling characteristics.


  • 32-Strand sheath for optimum sheath / core ratio

    Nice Static line, use many Brands on auxillary rescue team for work. Would stack this against any of them.
