Alpha® Locks and Suspension System

With the choice of pin-seal, incorporated valves, or the ability to switch from locking to suction, the Alpha lock range includes options to provide security and a comfortable fit for any amputee.

Alpha Lamination Lock

The Alpha Lamination Lock is small, light, and can be used in either a one- or two-step lamination. When incorporating an attachment plate in a two-step lamination, various angle options can be utilised to optimise foot alignment, without allowing the shuttle lock to dictate alignment. An airtight fit is achieved with a pin seal, sealing off the socket. One pin is included in each lock.

Alpha G-Lock

The G-Lock is equipped with a one-way expulsion valve which allows for both a suction attachment and a pin lock with seal.

Alpha Mini G-Lock

The Mini G-Lock is designed for application at the upper extremities (transhumeral and transradial), and can also be used for paediatric devices. The Mini G-Lock uses standard pin locking with pin seal.

Alpha Interlock Suspension System

The Alpha Interlock Suspension System offers versatility in one simple package, allowing you to interchange suspension methods between suspension and locking without remaking the socket. After installation of the distal adaptor in the socket, you can insert a pin lock, a lock Lanyard, or a Suction Insert. The distal adaptor can be used in lamination and thermoplastic sockets.

Alpha Suspension Lock

The Alpha Lock’s contoured design allows for easy pin alignment within the locking system, and includes a built-in one-way expulsion air valve to minimise pistoning. This lock is available with or without a titanium pyramid.

Alpha Lanyard

The Alpha Lanyard consists of a one-way expulsion valve plus a locking mechanism which utilises a pull-cord to trigger its release. This lock is available with or without a titanium pyramid.

Suction Insert

The Suction Insert is a lightweight suction device that is easy to fabricate into a socket using a common distal adaptor.
