- Quick-install top edge design provides secure, easy attachment for cold shoe fittings and prevents accidental detachment during use. - The 1/4 inch mounting screw is protected by three 9 mm anti-reversal holes, guiding anti-rotation pins to stop rotation and loosening, reducing the risk of the unit slipping or dropping. - CNC machined aluminum delivers a compact, miniature profile while keeping the weight very low to 12 g, enhancing portability without adding bulk. - The extension adapter is built from high quality CNC aluminum for reliable durability and stable performance during shooting sessions. - Compatibility and suitability: designed for standard 1/4-20 mounting threads, compatible with most cameras, lights, microphones, monitors, and other accessories that use a standard 1/4 inch screw. - Use scenarios: 1) Attach a compact LED light or small microphone to a camera rig or DSLR/mirrorless setup, using the anti-rotation holes to keep the accessory secure. 2) Extend a mounted accessory forward on a tripod or cage to improve balance or reach, while maintaining a tight, stable connection. 3) Add a small monitor or accessory on a gimbal setup where space is tight, benefiting from the lightweight design and secure mounting.
