Really Right Stuff B2-Duo 60mm Sliding Screw-Knob Style Quick-Release Clamp

How the B2-Duo 60mm Sliding Screw-Knob Style Quick-Release Clamp, a product of the reputable Really Right Stuff brand, revolutionizes your photography setup. This durable and high-quality clamp features dual mounting surfaces, allowing for the parallel positioning of two compatible plates or rails, one atop the other. This sturdy clamp is the perfect solution for securely mounting a Really Right Stuff lens or camera body plate on a Multi-Purpose Rail or Camera Bar. The B2-Duo is equipped with two nylon thumb screws, offering an independent clamping option separate from the main locking knob.

This feature is especially useful when mounting a telephoto lens plate on a Really Right Stuff camera bar, as it allows the user to fix the B2-Duo to the lens foot while still being able to slide the clamp along the camera bar for optimal positioning. The B2-Duo's versatile design is primarily intended for use with our Multi-Purpose Rails and Camera Bars. Its simple, low-profile design allows a collared lens or camera to be fixed in the top half of the clamp, while still enabling the B2-Duo to slide fore-aft (lens) or side-to-side (camera) on our Multi-Purpose Rail or Camera Bar.

This makes it an affordable focus rail/nodal point slide for collared lenses or a sliding stereo photography setup. Laser-engraved index marks on all four sides in the standard RRS zero, 12, and 18mm-on-center increments provide precision and ease of use. The two non-marring nylon thumb screws securely lock in place whatever is mounted on that side of the clamp. The B2-Duo can then be loosened using the main screw-lock knob to allow it to slide fore/aft or side-to-side on the Multi-Purpose Rail or Camera Bar. Please note that the B2-Duo clamp is only compatible with Really Right Stuff or Wimberly brand quick-release plates.

Due to the simultaneous adjustment of both clamping jaws by the main locking knob, all quick-release plates used with the B2-Duo need to have the exact same external dimensions. Mixing plates from other manufacturers might cause clamping fitment issues. The B2-Duo clamp should only be used with plates & rails from the same manufacturer.
