- QKM-05 Round Knob assembly (metric)
Seyco's round thumbscrew upgrade is simply fantastic for prevention or care of Carpal Tunnel Syndrome! The round knob is ready to grip when you reach straight into it therefore eliminating the need to be repeatedly ratcheting your wrist to align your thumb and finger with the position of the "T" knob. Our round knobs have the same precision machining as the original "T" knob to provide correct alignment and maximum gripping of the blades.
