A lightweight, dual-suspension pin system designed to combine suction suspension comfort with pin suspension security.  The airtight seal prevents air from coming into the bottom of the socket, creating suction and reducing pistoning.  Suspension sleeves are not required.  3 sizes and 2 depths available.  
The fabrication procedure for the Air-Lock saves time and money.  The Alignable or One-Shot connector is attached to the lock in the desired location for prosthetic alignment, allowing the lock to remain in ideal lock alignment for easy engagement.  A single stage lamination is done that incorporates the lock and connector into the socket.  The offset capabilty saves money by eliminating the need for offset components and saves time with a single lamination and easy component set up.
