Freedom of movement and comfort: Locks form the crucial connection between the liner and the prosthesis. They lock the liner securely in the socket and enable use without a knee sleeve.

Variants for all cases

Our locks are manufactured with high precision and offer a wide range of cover variants and various locking units.
Clutch locks can be locked variably and quietly, and the pin can also be retracted.

Shuttle locks snap into place with audible clicks. This gives patients the certainty that they are being held securely in the prosthesis. The shuttle locks are also particularly sturdy.

Easy locks are variably and silently locked. By using a pin with a drill hole, an additional cord can make it easier to put on the prosthesis.



Our locks make putting on and taking off the prosthesis particularly quick and uncomplicated:

Thanks to the Easy-Click system, the locks can also be unlocked under tensile load, making it easier to take off the prosthesis while sitting.

The optional lockable locking unit also facilitates handling: One twist is all it takes to keep the lock unlocked.

Suitable for everyday use

When using the locks, there is no need for a knee sleeve – this can improve freedom of movement and be more comfortable.

Different locking units give patients feedback and reassurance: Some prefer to put the prosthesis on silently, others feel safer with acoustic feedback when putting it on, some count the clicks.

A lock is also available in a waterproof version; this variant allows worry-free use in damp and wet areas, in the rain or when bathing.

Well thought-out workmanship

Different cover designs give you full flexibility in processing: They allow for many different configurations of fitted parts, accelerated socket construction or quick replacement of the entire lock. Some covers give you freedom in plumb alignment.

  • Series 100 and Series 150 have no weight limit.
  • Series 100 and Series 150 can also be installed independently of the plumb alignment.
  • In Series 200 and Series 400, the whole lock is replaceable.
  • Series 500 can be made in lamination technique with only one casting.

All locks are delivered pre-assembled; the matching lamination dummy set is always included.

We also offer a wide range of spare parts and accessories such as locking units or push button extensions. Good to know: The locking unit is very easy to replace.
