What are Knobs ?
Knobs are mechanical components designed to facilitate manual control of devices and equipment. They are widely used in applications such as new product design, engineering evaluation, and maintenance. Important specifications for selection include Diameter, which affects fit and usability; Material, which influences durability and environmental resistance; and Height, which can impact ergonomics and accessibility. Ensuring these attributes align with existing design constraints is crucial for effective sourcing and procurement.
