The Benro GDHAD1 tripod spacer provides additional clearance for photographic heads that might have control knobs that interfere with the tripod spider when placed in the downward position. This simple product was specifically designed for users of the Benro GD3WH who wish to fit it on a Benro Combination or similar design tripod that has a large diameter platform for the head. Simply fit between head and tripod to maximize full tilt movements of the head.
