OVERVIEW

Restore Precision Control to Your Industrial Equipment

In the demanding environment of industrial manufacturing and fabrication, the smallest components often play a critical role in daily operations. This Replacement Control Knob (SKU: W7004972) is designed to restore functionality to your equipment's interface, ensuring that operators can make precise adjustments safely and effectively. Whether you are replacing a lost knob on a power supply, a welding machine, or a piece of test equipment, this durable component is engineered to fit standard specifications.

Exact Dimensions for a Perfect Fit

Compatibility is key when sourcing replacement parts. This knob features a precise 1/4-inch inner diameter (ID), which is the industry standard for many potentiometers and rotary switches used in heavy machinery. The 1-inch outer diameter (OD) provides a substantial surface area for gripping, making it easy to rotate even when fine-tuning settings. With a height of 0.9 inches, it stands proud enough from the control panel to be easily accessible without obstructing other controls or indicators.

Built for Industrial Environments

Equipment in workshops and factories faces constant wear and tear. This control knob is manufactured from high-quality, impact-resistant materials capable of withstanding the rigors of daily use. Its robust construction ensures it won't crack or slip under normal operating conditions. The surface is designed to provide tactile feedback, allowing for confident adjustments. Maintaining your equipment's control panel not only improves usability but also enhances safety by ensuring that settings can be changed quickly and accurately when needed.

Versatile Application

While ideal for welding machines, the standard sizing of this knob makes it a versatile spare part for a wide range of industrial devices. From wire feeders to plasma cutters and fume extractors, any device utilizing a 1/4-inch shaft can benefit from this replacement. Keep your operations running smoothly and avoid the frustration of makeshift solutions by installing the correct part for the job.
