2.375" Arca-Swiss Compatible Quick Release Clamp | Long Black Knob

The 2.375-inch jaw length Arca-Swiss compatible clamp is a precision-engineered mounting solution designed for maximum versatility and field reliability. This model features a specialized long black captive knob with an integrated 5mm hex wrench port for high-torque tightening and a low-profile design that allows for mounting on flat surfaces without knob interference.

Quick Overview & Key Features

• Dual-Drive Long Black Knob: The ergonomic long knob includes an internal socket for a 5mm hex wrench, allowing for extra security or operation in tight spaces.
• Flat Surface Compatibility: Engineered so the knob does not interfere with the mounting plane, allowing the clamp to be bolted directly to flat plates or custom rails.
• Compact 2.375" Jaw Length: An ideal size for ball heads and travel tripods, providing a secure, high-tension grip without excessive weight.
• Captive Safety Mechanism: The knob stops at its maximum opening position, ensuring it cannot be backed out or lost while working in the field.
• Precision Dual Mounts: Includes two outside 1/4-20 tapped holes spaced exactly 30mm apart for specialized multi-point or anti-twist attachments.
• Versatile 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 studs.
• Safety Relief Grooves: 2.6mm deep relief grooves guarantee compatibility with Arca-type plates featuring safety stops, preventing gear "free fall" if the clamp is partially open.
• Anti-Twist Integration: The rear side features a dedicated registration groove to match professional ball head connections, effectively eliminating unwanted rotation during use.
• Premium Materials: Precision CNC-machined from solid 6061-T6 aircraft-grade aluminum with a durable black hard-coat anodized finish.
• Made in the USA: Manufactured to professional tolerances for lifelong reliability.

Professional Arca-Type Quick Release Solution

Upgrade your camera support gear with a professional Arca-style clamp built for technical precision. The "Micro-Vise" design ensures a tenacious, twist-free grip on any compatible plate from leading brands like RRS, Kirk, Wimberley, and Markins. The unique ability to use a 5mm hex wrench on the knob makes this clamp a favorite for permanent installations or setups where extra leverage is required.

Advanced Safety and Field Reliability: Built for the rigors of professional use, the 2.6mm deep relief grooves serve as a critical fail-safe against accidental gear drops. The back of the clamp includes a registration channel designed to mate securely with common ball head posts, eliminating the shifting common with heavy camera setups or vertical shooting. This clamp delivers the structural integrity and precision required for advanced macro, landscape, and technical photography.
