The lowest build height, lightest weight lock available.The Prosthetist can interchange the Ratchet Pin, Smooth Pin, Lanyard, and Valve using the same socket. This provides the amputee with the option of trying different suspension methods to consciously choose the most appropriate one for his or her activity levels. New amputees also benefit from this interchangeable system, as they can begin the rehabilitation program with a Lanyard and then change to a Pin or a Valve as they progress. The reusable fabrication tooling kit (L-680000) was developed to facilitate the socket fabrication procedure using the Icelock 600 series locks. The Icelock 600 series can be used with lamination manufacturing techniques (single or double applications) with an Alloy 4-hole, Stainless Steel Pyramid for body weights up to 220lbs / 100kg, Titanium 4-Hole Pyramid or Titanium Pyramid for body weights up to 365lbs / 166kg.
