Climbers, whether mountain or tree climbers, will often think that the words “HMS carabiner” and “compact” can not go together. With the ISC Mighty Mouse Carabiner, however, these two features are successfully combined. International Safety Components, Inc., the manufacturer, refers to the Mighty Mouse as a Mini-HMS.
In spite of its small and compact size, this carabiner has superior strength as it is made of forged 7075 aluminium alloy, that is, aluminium alloyed with zinc. This material is also called aerospace aluminium as it is often used for aircraft construction, particularly the wings and fuselage. It comes polished and anodized to make it more attractive and scratch-resistant.
Being an HMS, a Munter hitch can easily be tied even with a ½-inch line. A wide gate measuring 20 mm also helps this. The spine is thicker than the top and bottom portions. This helps keep a tight eye splice or a cinching knot in their proper place. As it is small, it is rather unobtrusive making it ideal for attaching ascending devices and rope grabs to your saddle attachment rings.
The Mighty Mouse is available in four different types of locking mechanisms –the screwgate, twistlock, supersafe, and quadlock. In addition to the choices of gates, color option is also available.
