The Pro key is our completely new nut key. With a host of great features including our new leash to make it easier to help you free up your 'too expensive to leave behind' rack of shiny beauties. The 2008 Nut Key offers more, and should save you in retrieving 'lost' pro.... A radical update makes this tool more adaptable and easier to use. The Pro key comes with a new precision ground tip which allows access to the smallest slots, as well as a wire gate at the top which allows a direct clip to the harness. Added to this, a one piece a 'folded top' gives a bigger surface area to allow a firmer less painful push with the palm and large central holes keep the weight down. Finally, and exclusively, the Pro Key is available with an extendable detachable and flexible leash which can be clipped via a mini wiregate biner to your harness preventing loss in extreme positions.
