Shoulder straps are used for carrying a wide selection of Porta-Brace cases. The HB-20, with its wide leather soft foam pad, distributes weight across the shoulder. The HB-40 and HB-10 are contoured suede leather designed to fit comfortably in the hollow of the shoulder. The swivel snap hooks attach to rings across Porta-Brace cases. The Specialized Camera Straps connect directly to your camera's posts for easy transport.
