DimcoGray Knobs

DimcoGray is widely known as a manufacturer of quality knobs. With its attention to detail and emphasis on quality control, the company has turned these simple tools into integral components in a wide variety of settings. It is no wonder that customers look towards DimcoGray for products that provide ease of operation and high levels of reliability. Reid Supply has an extensive collection of DimcoGray knobs for different applications.


Ball knobs are common in levers that shift from left to right or up to down. DimcoGray’s selection of ball knobs features a simple yet comfortable design. Made from either thermoset or phenolic, these products come in different sizes, from the smaller 1/2-13" to the larger 5/16-24". Customers can also choose from among different knob designs: spherical, oval, or recessed-top.


Lobed knobs are distinguished by their scalloped edges. These allow for optimal grip and comfort when tightening, loosening, or adjusting certain equipment. Dimco Gray offers lobed knobs made from brass, steel, or stainless steel that are perfect for both indoor and outdoor applications.


Reid Supply also carries DimcoGray’s line of push/pull knobs with selections for round and recessed-top designs. These products come in either phenolic or ABS plastic variations. Either way, Dimco Gray supplies push/pull knobs that are known for their ergonomic design and durability.


For tapered knobs, DimcoGray offers thermoset female handles for operating heavy-duty equipment and other applications where a firm yet relaxed grip is required. Oval tapered handles are also available in our catalog of DimcoGray products. They also come with a threaded brass insert and a glossy finish that allows for a comfortable grip.


We also carry a wide selection of wing knobs from DimcoGray. These products provide optimal comfort when making adjustments to a piece of equipment by hand. Available wing knob shapes include flared, wedge, and thumb. They are made from polypropylene with a brass insert. Apart from threaded variations, we also supply threaded stud and threaded insert types. Most of the wing knobs we carry come in black, but we have flared threaded insert knobs that come in red.
