Product Description

The F52 Perpendicular Double Clamp provides a rock-solid bridge for photographers building multi-axis rigs. By allowing two rails to attach at a perfect 90-degree angle, it is a key component for creating vertical masts in panoramic photography or constructing custom lens support brackets for heavy telephoto glass.

Beyond rail-to-rail connection, the F52 is equipped with a center socket, offering the flexibility to be mounted directly onto compatible ball heads or other supports. This versatility makes it an indispensable "problem-solver" in a professional gear kit.

Safety and reliability are paramount. The deep relief grooves ensure compatibility with nearly all Arca-type plates and rails. When used with plates featuring safety stops, these grooves prevent the camera or lens from sliding out if the clamp is accidentally left partially open. Both knobs are fully captive, ensuring they remain attached even at maximum opening. CNC-machined from 6061-T6 aluminum and hard-coat anodized, the F52 is built to endure the most demanding field conditions.
