This device will absolutely change the way you perform rope rescue (see videos linked below). The Scarab® represents five years of research and testing by Rick Lipke and the design team at Conterra. It was born out of the need for a small, simple device that could easily control heavy rescue loads, as well as excel at pick offs, twin rope systems and other general rescue techniques. The Scarab® does all this and more. With two models available, the Scarab® is the perfect choice for both Fire/Rescue and back country rescue environments: Incredibly strong Does not twist the rope Instantly adjustable friction (just wrap a horn) Lower 600 lb loads with two fingers Super easy lock off Easy to use, right or left handed Single and double rope capable Attach rope without unclipping from anchor Technical Specifications Titanium MBS20 kNRope Compatibility 6 – 11 mmWeight185 g Certifications NFPA G (for 12.5 mm rope)
