Frequently Asked Questions
What wire gauge does this plug accommodate?
The side entry port fits wire sizes from 22 AWG to 18 AWG, clamped securely by the internal set screw.
Can multiple plugs be stacked into this connector?
Yes. The body features both a rear jack and a side-entry port that accept standard 4 mm banana plugs for multi-connection patching.
What tool is needed to tighten the wire connection?
A standard flat-blade screwdriver secures the internal 8-32 set screw against bare wire strands; no soldering iron or crimp tool is required.
Nothing beats building a test lead exactly to length right at the bench. Strip a few millimeters of wire, snug down the set screw, and get back to troubleshooting.
