Comments about Todd Todd Knob and Shaft Replacement Part:
The design of the product is good, usefull and easy to use. The aluminum shaft is a poor choice of materials. When it is attached to the stainless bolt, the disimilar metals cause galvanic corrosion to the bolt and knob welding them together rendering the adjustability useless. Manufacture the knob's stem out of Stainless Steel and this will eliminate the problem.
