1/4"-20 Threaded Stud Mount Base — 1.5" Ball, C-Size (Action Camera / Tripod / GoPro Compatible)

The 1/4″-20 threaded stud is the bridge piece that drops any camera, tripod plate, or action-cam adapter into the C-size 1.5″ ball-mount ecosystem. Fixed to the back of the ball is a stainless-steel 1/4″-20 male stud — the universal photo-tripod thread — so anything with a 1/4″-20 socket on its base will screw straight on.

Built for the bush, the boat, and the ute

• Pair it with a windscreen suction cup, dash bracket, or roll-cage clamp from the C-size range and you have a full mount in two pieces.
• Mount a dash camera or 360° camera to your 4WD windscreen for trip recording on remote tracks.
• Run a fish finder, GPS plotter, or chart-light on the boat — any device with a tripod thread on the base will fit.
• Use it as a tripod-to-bar adapter for action cams, gimbals, or compact mirrorless bodies on a roll cage, awning pole, or roof rack.

Specifications

What is C-size?

C-size is the industry-standard 1.5″ ball used by the larger end of modular mount systems. The bigger ball gives extra holding torque versus the smaller B-size 1″ ball — ideal for cameras, fish finders, and any kit where a knock or corrugation could shift a smaller mount.

What you get

• 1 × 1.5″ ball with 1/4″-20 stainless steel stud
• Rubber-coated ball for shock absorption and grip inside the socket arm
• Compatible with all standard 1.5″ (C-size) double-socket arms — including RAM Mounts

Shipped from our Australian warehouse. Pair with a C-size double-socket arm and base to complete the mount.
