Arca/Pic rail anodized aluminum 5.1"

Arca/Pic Rail: overview, dimensions and practical use

The Arca/Pic Rail is a compact, versatile mounting component that bridges Arca-Swiss style clamps and Picatinny rail accessories, providing a lightweight solution for attaching cameras and gear to tripods, plates, and adapters. This unit weighs 1.8oz (without screws), making it suitable when minimizing system weight is essential without compromising stiffness. Its overall length is 5.1", with a Pic Rail segment of 1.970" and an Arca segment of 2.43"; these dimensions allow flexible placement in tight setups. Constructed from anodized aluminum, the rail balances strength and low mass, while the anodized finish improves abrasion and corrosion resistance and reduces glare in photographic environments. The package includes the mounting hardware: a black-oxide alloy steel flanged button head screw, 10-32 thread, 1/2" long, and a black-oxide alloy steel hex drive flat head screw, 10-32 thread, 1/2" long. These screws ensure a reliable attachment to plates or bases and allow installation with standard tools. By combining Arca and Pic functionality, the rail enables quick transitions between Arca clamps and Picatinny accessories without extra adapters, ideal for photographers and operators who reconfigure setups frequently. For a stable connection, check screw torque with the correct driver and ensure mating surfaces are clean and free of burrs. The 5.1" compact footprint is especially useful for mobile rigs, lightweight video setups, and L-brackets where space is limited but modularity is required. Knowing each segment length helps position the camera and verify compatibility with existing clamps or mounts, preventing interference with handles, ports, or nearby fixtures. In short, this rail offers compact dimensions, quality materials and included hardware to deliver a practical, lightweight option for mixed Arca/Picatinny mounting requirements.

Technical specifications

• Weight: 1.8oz (without screws)
• Overall length: 5.1"
• Pic Rail length: 1.970"
• Arca length: 2.43"
• Material: Anodized aluminum
• Screws included: Flanged button head, 10-32, 1/2"; Hex drive flat head, 10-32, 1/2" (both black-oxide alloy steel)

Recommended installation: clean the contact surfaces and remove debris before mounting. Position the rail and start threads by hand to ensure alignment, then tighten the screws with the correct driver. Avoid over-torquing; firm, even tightening secures the rail without deforming components. Recheck fasteners after initial use to accommodate any settling.

Care and maintenance: keep the anodized aluminum surface free of dust and moisture to preserve finish and function. Clean with a soft cloth and mild cleaner if needed, avoiding harsh chemicals. For black-oxide screws, a light corrosion inhibitor is recommended in humid or salty environments to prevent seizing and facilitate disassembly.

Usage tips and compatibility: verify compatibility of Arca-style clamps and Picatinny accessories before final assembly, taking the rail segment lengths into account for optimal placement. Place the Pic segment where short accessories will mount and reserve the Arca portion for the camera plate interface. These practices improve balance, ergonomics and speed when swapping gear.
