What is an L-Bracket and why use one?
An L-Bracket allows a camera to be mounted to a tripod in both horizontal and vertical orientations while keeping the camera centered directly over the support system. This improves balance, reduces stress on tripod heads, and helps maintain consistent framing when switching orientation—especially when working with heavy lenses, panoramic setups, or precision compositions.

Built to the RRS 1.5″ dovetail standard, they integrate seamlessly with professional tripod heads and quick-release clamps used in still photography, video, and hybrid workflows.
