The B2-Duo is a versatile double clamp designed primarily to use with our Multi-Purpose Rails and Camera Bars. The simple, low profile design allows a collared lens or camera to be fixed in the top half of the clamp and still allow the B2-Duo to slide fore-aft (lens) or side-to-side (camera) on our Multi-Purpose Rail or Camera Bar. This makes for an affordable focus rail/nodal point slide for collared lenses or a sliding stereo photography set-up.
- Index marks are laser-engraved on all four sides in the standard RRS zero, 12 and 18mm-on-center increments.
- Precision CNC machined in the USA from solid aircraft aluminum and finished in a beautiful matte-black anodize. All excess mass is removed to minimize weight and all corners are radiused for beauty and comfort.
- 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.
The B2-Duo clamp should only be used with plates & rails from the same manufacturer. Due to the nature of the single clamping jaw (i.e., clamps both top and bottom plates simultaneously), this clamp cannot accommodate Arca-Swiss style plates that vary in width.
