Petzl kootenay

Block with large opening for the passage of knots. Designed to be used on ropes that are either spliced or have a knot on them for other reasons. Very large wheel mounted on encapsulated ball bearings for maximum efficiency. Large space between the wheel and the top of the side plates to allow knots to pass. Locking pins on the wheel allow the block to be used also as an anchor. Individually tested.
