The Kirk Manfrotto 3271 Quick Release Clamp is a specialty Arca-Swiss-type clamp that allows you to add Arca-type plates to your Bogen professional RC4-type quick release. The clamp is made of lightweight aluminum and stainless steel construction, to provide long-lasting dependability. No internal mechanisms are exposed and this clamp is engineered with safety stop relief grooves that provide improved versatility when mated with Kirk camera plates.
Kirk plates are designed so that they will slide halfway across the clamp before stopping, giving you greater control without sacrificing flexibility.
Just one quarter turn of the locking knob allows the camera mounted to the plate to be easily adjusted along its path or, if the safety stops are not used, to be removed entirely from the side. A full turn allows the camera to be removed from the top.
