SOMETHING DIFFERENT TO TWIST LOCKS! The Mighty Mouse Mini HMS is a new design of locking karabiner. In order to unlock this karabiner you must squeeze both of the rings around the gate together simultaneously. These rings are also able to spin around the gate. Opening caused by rubbing of the gate is therefore greatly reduced. This new karabiner conforms to both EN 362 and meets ANSI z-359-1 The Mighty Mouse is also available in quad lock" and spring lock options.

Conformance: EN362, ANSI Z-359-1
