4.00" Arca-Swiss Compatible Quick Release Clamp | Short Silver Knob

The 4.00-inch jaw length Arca-Swiss compatible clamp offers a heavy-duty, precise mounting interface for professional camera rigs and telephoto lenses. Equipped with a compact, high-torque short silver knob, this quick release system delivers maximum holding power and stability without adding unnecessary bulk to your tripod setup.

Key Features & Quick Overview

• Extended 4.00" Jaw Length: Spreads gripping pressure evenly across the rail for an ultra-secure hold on large format gear.
• Short Silver Knob: Engineered with a captive design that stops at maximum opening so it can never be lost or dropped in the field.
• Dual 45mm Threaded Mounts: Features two outside 1/4-20 tapped holes spaced exactly 45mm apart for specialized dual-point mounting.
• Versatile Center Socket: Countersunk on top for clean screw placement and internally threaded for standard 3/8-16 studs.
• Fail-Safe Relief Grooves: Machined 2.6mm deep relief grooves accommodate plates with safety stops, preventing gear free fall if the jaw loosens.
• Anti-Twist Alignment: Rear alignment groove mates perfectly with compatible ball head connections to eliminate unwanted rotational twisting.

Heavy-Duty Camera Support with Anti-Twist Design

Engineered for precision and built to withstand rigorous field use, this 4-inch quick release clamp provides seamless interoperability with Arca-type plates and rails. The low-profile short silver knob ensures swift locking transitions while keeping the overall footprint streamlined.

The specialized back-side alignment groove secures your connection to modern ball heads, eliminating the shifting or twisting common with heavy lens systems. Combined with built-in safety relief paths, your investment remains fully protected during micro-adjustments or fast-paced shooting scenarios.
