3.00" Modular Arca-Swiss Lens Support with 1.150" Wheels

The Hejnar Photo 3.00-Inch Modular Lens Support System is a precision stabilization kit engineered to eliminate structural flex in professional telephoto setups. This configuration bundles our 3-inch Arca-style rail with a standard supporting bar and 1.150-inch diameter roller wheels. Designed for maximum versatility, it can be bolted directly to your rail for a permanent setup or placed into a quick-release clamp for rapid vertical height adjustments. Proudly CNC-machined in the USA from solid aircraft-grade aluminum.

Quick Overview & Key Features

• Fluid Roller Stabilization: The 1.150" wheels provide a dynamic contact point, allowing the lens to glide effortlessly when rotating the collar between landscape and portrait orientations.
• Modular Versatility: Part of a fully interchangeable system—adjust height and reach to match your specific lens diameter and camera body perfectly.
• Flexible Mounting Options: Mount directly to the rail via a 1/4-20 captive screw for maximum stability, or utilize a quick-release clamp on the rail end for tool-free vertical tuning.
• Eliminates Mirror Slap & Vibration: Creates an unyielding physical bridge that keeps the focal plane static during high-magnification or long-exposure captures.
• Protects Camera Mounts: Disperses heavy front-end optical weight, removing cantilever stress from the camera's native bayonet lens mount.
• Universal Standard: The 3-inch rail base interfaces seamlessly with professional quick-release clamps from RRS, Kirk, Wimberley, and Markins.

Detailed Product Description

The Hejnar Photo 3.00-Inch Modular Lens Support Bracket is the definitive solution for photographers seeking professional-grade stability in an adaptable footprint. While static "universal" supports can bind against the lens barrel, our precision 1.150-inch roller bearing wheels ensure smooth tracking and adjustment, making it a favorite for wildlife and sports photographers who need to switch orientations rapidly.

What distinguishes this specific package is its "hybrid" mounting capability. For dedicated studio setups where height rarely changes, the support bar can be bolted directly to the 3-inch rail using the provided 1/4-20 captive screw. For field photographers who utilize multiple lens systems, the bracket is also designed to be placed into a quick-release clamp. This allows for instant vertical calibration without needing hex tools—simply slide the assembly to the target height and lock the clamp.

Machined from solid blocks of 6061-T6 aircraft alloy and treated with a durable hard-coat anodize, this USA-crafted system is built for the rigors of field use. It offers the same precision and reliability found in high-end brands like Really Right Stuff, while providing the unique modular freedom that allows your camera rig to grow and adapt to any future hardware configurations.
