The Leofoto LSC-52A Lever-Release Arca Clamp isconstructed from solid aircraft grade aluminum and hard anodized for the maximum strength and durability. It features a lever release for quick and easy attach/detach and have a width adjustment screw for non-standard arca rails.
Great quality as usual - I added this to my Leofoto VR-250 250mm Dual Pivot Long Tele Lens Support to enable me to rotate camera from landscape to portrait orientation more easily than unscrewing and re-screwing the camera every time.
