What it does

Clips onto your multimeter probes so you can hold them steady with one hand while you work on circuits
Multiple designs fit Klein, Fluke, and budget probe sets, so you get the right fit for your tools
Wide versions let you touch probes together for zeroing your ohmmeter without fumbling
Made from durable 3D-printed material that grips firmly and lasts through heavy workshop use

Hold your multimeter probes steady with one hand. This adapter clips onto your probes like tweezers, freeing up your other hand to adjust circuits, test connections, or take notes. No more juggling probes and tools at the same time.

The design comes in four versions to match what you own. We have adapters for Klein tools FC-97 probes, Fluke probes, and even cheaper brands from hardware stores. The wide versions give you extra space to touch both probes together when you need to zero your ohmmeter. This adapter is 3D printed on demand from the US, so you get a custom tool made just for your setup.

Best results come from printing with PETG material at 3 walls and 100 percent infill for strength. Your probes will clip in tight and stay put while you work.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
