The Aero HMS has several features which raise it above the competition.

For a start it’s hot forged – a process that allows a much greater degree of freedom in the design and manufacturing process. A product of this very freedom is the anti snag Keylock nose. And then there is the extremely generous rope radius – a whopping 11.3mm!

It is also a very strong biner, and while it might not be the lightest Screwgate around, this extra bulk means greater resistance to wear and excellent heat dissipation – something you will appreciate on your next big abseil.
