The KK Spikecender SAKA Spacer is an optional extra for the KK Spikecender - you can attach your SAKA or foot loop directly to the spacer using a small carabiner - the DMM XSRE carabiner is ideal for this application. This feature eliminates annoying foot loop issues and minimises the amount of rope need under the hand ascender or SAKA. The KK Spikescender SAKA Spacer fits beneath the gaff on the opposite side to the KK Spikescender to ensure both gaffs are equidistant from the shaft. Make sure you use the extended stainless steel bolts to fit Gecko gaffs - the original bolt is too short. The American Short gaff is ideal when used in this application.
