Upgrade your tripod system with this precision-engineered Arca-Swiss compatible clamp. Designed for photographers who demand absolute reliability and modularity, this 3.25-inch screw-knob clamp provides a rugged and versatile mounting solution for professional camera systems and telephoto lenses.

Key Features & Quick Overview

• Dual Mounting Interface: Center socket is countersunk on top to fit 1/4-20 and M6 screws, and is also natively threaded for 3/8-16 studs.
• Captive Knob Design: The one-piece knob is captive to prevent loss in the field and features a sealed design to block dust, sand, and grit intrusion.
• Safety Relief Grooves: Integrated 2.6mm deep grooves accommodate plates with safety stops, preventing gear "free fall" if the clamp is partially open.
• Tongue-in-Pocket Design: Internal mechanism keeps jaws perfectly aligned and protects moving parts from the elements.
• Professional Ergonomics: Features rounded edges to prevent injury and gear damage during fast-paced shoots.
• Premium Construction: CNC-machined from solid 6061-T6 aircraft-grade aluminum with stainless steel hardware.
• Durable Finish: Black hard-coat anodized clamp surface with a clear anodized knob for superior abrasion resistance.
• Made in the USA: Built to professional-grade tolerances for lifelong reliability.

Rugged Precision for Professional Gear

This 3.25-inch quick release clamp is the perfect middle-ground for photographers needing more surface contact than a standard 2-inch clamp without the footprint of a 4-inch rail. Its "Micro-Vise" design delivers a tenacious, twist-free grip on any Arca-type plate from major brands including RRS, Kirk, Wimberley, and Markins.

Whether you are building a custom macro rig or upgrading a ball head, the dual-mounting center socket ensures compatibility with nearly any tripod or monopod stud. The precision-milled registration paths and hard-anodized finish ensure that this clamp remains a staple in your kit for years to come, providing the structural integrity required for high-end technical photography.
