3.25" Arca-Type Quick Release Clamp with Integrated Bubble Level

The 3.25-inch Arca-type quick release clamp is a precision-engineered hardware solution designed for photographers who require exact alignment and absolute security. Featuring a high-visibility long silver knob and a built-in bubble level, this clamp provides a professional-grade foundation for tripod heads, gimbal systems, and custom modular rigs.

Quick Overview & Key Features

• Integrated Bubble Level: Built-in spirit level ensures precise horizontal alignment for architectural, panoramic, and landscape photography.
• 3.25" Jaw Length: Optimized surface area for a rock-solid grip on Arca-Swiss style plates and rails.
• Long Silver Captive Knob: High-leverage design for easy tightening; captive mechanism stops at maximum opening so it cannot be lost in the field.
• Versatile Mounting Interface: Center socket is countersunk on top and natively threaded for 3/8-16 studs; includes two outside 1/4-20 tapped holes spaced 45mm apart.
• Safety Relief Grooves: 2.6mm deep grooves prevent gear "free fall" by catching safety stops on Arca-type plates if the clamp is partially open.
• Anti-Twist Integration: The rear side features a dedicated groove to match professional ball head connections, preventing unwanted rotation during use.
• Premium Construction: CNC-machined from solid 6061-T6 aircraft-grade aluminum and finished with a durable black hard-coat anodize.
• Made in the USA: Built to professional-grade tolerances for lifelong reliability.

Professional Arca-Swiss Compatible Mounting Solution

This 3.25-inch clamp is a versatile and robust solution for upgrading tripod heads or building custom photography setups. The precision-machined "Micro-Vise" design ensures a tenacious, twist-free grip on any compatible plate from major brands like RRS, Kirk, Wimberley, and Markins.

Advanced Safety and Field Reliability: Engineered for the rigors of field work, the integrated 2.6mm safety relief grooves serve as a critical fail-safe against accidental gear drops. The back of the clamp features a registration channel designed to mate with common ball head posts, eliminating the shifting or twisting common with heavy lens systems. With its multiple mounting points and integrated level, this clamp offers the structural integrity and precision required for high-end technical photography.
