Tripod Accessory Manfrotto 386B-1

The Manfrotto 386B-1 Nano Clamp is a compact and lightweight aluminium clamp designed to give photographers a secure and versatile attachment point for lighting and camera accessories. Weighing under 110 g, it provides a portable solution for mounting gear to tripods, light stands, poles, shelves and other supports while supporting payloads up to 4 kg. The clamp features two female attachment sizes (9.5 mm and 6.35 mm) and is compatible with common anti-rotation adapters and friction arms.

Advantages

The Nano Clamp combines a durable, lightweight aluminium body with a patented unexposed thread system and a high-performance pull-and-lock handle for reliable operation. Its unique surface profile and included high-friction tape improve grip on both round and flat surfaces. Despite its small size, the clamp supports up to 4 kg and offers broad compatibility via 1/4" and 3/8" threads (9.5 mm and 6.35 mm female attachments), making it a practical accessory for compact kits.
