The VAL-1000 is a completely steel vertical alignment fixture for plastic and laminated prosthetic sockets. The VAL-1000 has three independently locking arms that slide along the same vertical track. The top arm slides in and out with a pipe collar locked in 90 degrees. The pipe collar holds ½" water pipe and conduit, and is also small enough to slide inside the R2 and LI platforms for perfect fabrication every time. The middle arm of the VAL-1000 moves independently in all directions. Separate handles control in/out, up/down, flexion/extension, and adduction/abduction for the ultimate control of your check socket alignment. The bottom arm holds very heavy casts without any flexing that can affect your alignment, and is adjustable left to right with a locking bottom tray. The VAL-1000 mounts to any table or LI work station, and has oversized and custom arms available to fit your needs.
