iBOLT 25mm to 38mm Composite Extension Ball Adapter for Industry-Standard Dual Ball Socket Mounts (B to C Size)

Overview

The iBOLT 25mm to 38mm Composite Extension Ball Adapter adds flexible reach and adaptable mounting to your existing setup. Crafted from a durable composite material, this lightweight adapter is designed to work with industry-standard 1 inch / 25 mm arms and 1.5 inch / 38 mm sockets, giving you more angles and placements without sacrificing stability.

The ball joints are surfaced with a rubber coating for a smoother, quieter rotation and a comfortable grip when adjusting positioning. The ball diameter range spans from 25 mm to 38 mm, enabling a simple, visual way to confirm compatibility across different mounts. The overall length of the unit is 2.5 inches, providing a compact extension that still offers meaningful reach for precise alignment.

What you gain

• converts and extends between common 25 mm and 38 mm ball systems, expanding mounting options.
• rubber-coated ball joints enable easy, steady repositioning with minimal drift.
• sturdy composite construction withstands daily use in studio, workshop, or field environments.

Key specs and compatibility

• 25 mm to 38 mm
• robust composite body with rubber-coated joints
• 2.5 inches (arm-to-arm span)
• 360 degrees of adjustability for full directional freedom
• works with industry-standard 1 inch / 25 mm and 1.5 inch / 38 mm mounts

Use cases vary from extending an arm to bridging different mount sizes. If you’re pairing with Bizmount series mounts or other B size / C size systems, this adapter provides a practical bridge for multiple configurations.

Note: the measurement to verify compatibility refers to the ball diameter, not the length of the entire adapter. Measure the ball diameter at its widest point for an accurate match.
