This unique adjustable daisy strap from Yates incorporates a heavy duty cam buckle that allows you to very quickly and easy adjust the precise length of a connection from your harness to an anchor, and is often used by aid climbers, big wall climbers, alpinists, and rope access and rescue professionals. These types of tools are not designed to be used as primary attachments to belay anchors, and are meant for body weight applications only. Carabiner not included.
