TitanLock Manual Knee

For the K1 ambulator whose first requirement is that the knee never buckle, the TitanLock locks at full extension automatically and stays locked until the wearer releases it to sit. The release lever is positioned for one-handed operation and tuned light enough for arthritic hands, with an optional remote pull-tab routed to the socket brim.

The lock is a hardened steel bail engaging a machined detent across the full axis width — no point loading, no creep as parts wear. Frame is forged aluminum, weight 560 g, build height 128 mm, free-swing flexion when unlocked 130 degrees, rated to 136 kg.
