Our Plastic 4-Star Knobs are excellent for applications requiring style, comfort, and a secure grip. The efficient design makes them easy to grasp and turn. The smooth lines and rounded edges make our Plastic Four Star Knob a popular choice for consumer product applications, such as office furniture and medical equipment where a comfortable grip is paramount. When you need a knob that conveys the ultimate image of luxury and quality, consider our Soft Touch 4-Star Knob with an over-molded layer of supple rubber for a sure, comfortable grip available in our 4S2, 4S4, and 4S5 knobs. Four Lobe Knobs are also available with a two-toned color scheme to add extra sizzle to your design and make your product stand out in a crowd. Decorate your knob with a pad printed or hot stamped logo or design for a truly unique look. With knob diameters that range from 1 1/8” to 2”, we have a knob that is perfect for any application. Our Plastic Four Star Knobs are available in male, female thru, female blind, and female locking versions with either inch or metric threads. Our plastic knobs are molded using Polypropylene, nylon, or ABS, which makes them up to twice as impact resistant as similar phenolic knobs. Custom inserts, custom hubs, and RoHS compliant parts are available upon request. Contact Innovative Components today to learn about our custom molding options.
