4 Arm Prong Knobs

In stock

Lobed knobs, also called clamping knobs, have a scalloped edge with four grip points to allow for maximum grip and comfort, even while wearing gloves.

These durable lobed knobs are impact- and chemical-resistant and provide a neat appearance for finished applications that require precision adjustments.

Reid Supply has a wide range of 4-lobed knobs, from plastic knobs to stainless steel and iron in a variety of thread sizes and mounting types.

Learn more about what solutions exist for your application in our article on selecting the right knobs and handles.
