Kirk calls it the Big "L" - short. Must be used with Kirk Arca style quick release body plate. Lets you quickly turn from landscape to portrait orientation rather than fiddle with tripod head movement.
Kirk gets $109.95 for this. I've used it for a couple of years - $75 USD & its yours. Includes mounting allen head screw & wrench. Buyer pays shipping.
