Get a Grip: Miller 261230 T-Knob Replacement

There is nothing more frustrating than a broken or missing knob on your welding rig. Whether it snapped off during transport or stripped out after years of hard use, a missing adjustment knob can turn a simple setup task into a headache. The Miller 261230 Knob is the direct, genuine replacement you need to get your machine back in fighting shape. Don't settle for generic hardware store hacks that don't fit right or look out of place; this is the exact part designed by Miller for your specific equipment.

This isn't just any knob; it's a T-style handle designed for the real world. If you are wearing thick welding gloves, trying to turn a small, round knob can be a nightmare. The 2.5-inch bar on this T-knob gives you plenty of leverage and a solid surface to grab onto, making it easy to tighten down or loosen up, even with your PPE on. It features a standard .312-18 (5/16-18) thread, so it spins right onto the existing studs on your machine without binding or cross-threading.

Made from tough, durable plastic, this knob is built to handle the shop environment. It won't rust, and it provides a safe, insulated touchpoint on your machine. It is often used for securing covers, access doors, or adjustable assemblies on wire feeders and power sources. Keeping your machine's exterior parts in good condition is about more than just looks; it ensures that covers stay closed to keep dust out and protects the internal components from damage.

Installation is as easy as it gets—just spin it on. No wrenches or screwdrivers required. If you are refurbishing an older Miller welder or just need to replace a part that walked away, the Miller 261230 is the quick fix that restores the professional look and functionality of your gear. Check your manual to confirm this is the part you need, and get back to laying beads without fighting your equipment.
