Edelrid HMS Bulletproof Screw

2 reviews   |  

The Edelrid HMS Bulletproof Screw is an innovative, robust HMS carabiner with a steel insert at the top part of the rope basket to prevent wear and sharp edges.

Also making a lighter, durable alternative to a steel carabiner for top-roping, the Edelrid HMS Bulletproof Screw is made from mostly of aluminium, with the exception of a steel reinforcement element. Lightweight yet providing protection at the point that is most susceptible to abrasion, the HMS Bulletproof Screw solves one of the greatest problems experienced by sports climbers: edge wear.

enduring locking carabiner

I don't think anyone these days makes bad gear. As you would expect from a company like Edelrid this is a well-made bit of kit that handles well. I particularly like the stainless steel re-inforced surface to eliminate wear from the rope. I expect this to last a lifetime.
