Now reworked with forged sideplates the Ropeman 2 is neater in the hand, a touch lighter and with better internal radii it has a smoother function across a broader range of karabiners. * The Ropeman2 was the successor to the Mk1 and was designed with stainless steel cam that allows use on ropes down to 8mm. * Thus the bottom line and the most reliable piece of safety advice is to follow the simple rule that the Ropeman1 is for single ropes only while the Ropeman2 will cover both half ropes and single ropes. * Strength: 15kN * Weight: 92g / 3.25oz
