3.25" Arca-Swiss Compatible Back-to-Back Clamp Set

This 3.25-inch Arca-Swiss compatible clamp set is a heavy-duty modular mounting solution that allows two independent clamps to be joined into a rock-solid back-to-back configuration. Utilizing precision aligning pins and bushings, this set creates a rigid coupler for connecting two Arca-style rails or plates, providing the maximum stability required for large-scale macro photography and professional panoramic rigging.

Quick Overview & Key Features

• Back-to-Back Modular Assembly: Set includes two 3.25" clamps that can be mounted together using provided aligning pins and bushings to prevent twisting under heavy loads.
• Versatile Orientations: Clamps can be assembled in various orientations to suit your specific rigging needs (Note: Set cannot be assembled with both knobs facing the same direction).
• Independent Operation: When disassembled, both components function as high-performance, professional-grade Arca-type clamps for tripods or monopods.
• Universal Mounting Interface: Center socket is countersunk on top for 1/4-20 or M6 screws and is also natively threaded for standard 3/8-16 tripod studs.
• Long Silver Captive Knobs: High-visibility, ergonomic design ensures the knobs stop at maximum opening and cannot be lost in the field.
• Safety Relief Grooves: Integrated deep grooves (2.6mm) prevent gear "free fall" when using plates equipped with safety stops.
• Anti-Twist Integration: Rear-side registration grooves match professional ball head connections for a shift-free mounting interface.
• Premium Construction: Precision CNC-machined from solid 6061-T6 aircraft-grade aluminum with a durable black hard-coat anodized finish.
• Made in the USA: Manufactured to exacting professional tolerances for lifelong reliability.
