Telescoping gauges exist but good ones are expensive and cheap ones are floppy. So I made this. Two rods ride in tracked channels to stay aligned, a knurled knob locks them down with a simple friction clamp, and the push plate is captured so nothing falls apart when you're fumbling inside a cabinet.
