Product Overview
The Cal Test Electronics CT3134-2 is an in-line female 4mm banana jack designed for custom test lead assembly and field bench repairs. The assembly features a three-piece design consisting of a nickel-plated brass contact barrel with dual set screws, a ribbed central insulating sleeve, and a rear strain-relief collar. Wire termination is completely solderless, securing stranded lead wire directly with two set screws using a 1.5mm hex key. The fully shrouded exterior provides recessed contact protection and bears a molded CE marking.

Frequently Asked Questions
What size hex tool is needed to tighten the set screws?
The dual set screws on the contact barrel tighten with a standard 1.5mm hex wrench.
What components are included with this connector?
This item includes the complete three-piece assembly: the red outer ribbed sleeve, the red strain-relief tail, and the dual-screw metal contact pin.
Why buy individual connectors here rather than a bulk variety pack?
You get the exact red in-line connector you need for your bench without paying for unused colors or bulk minimums. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, qualify for free shipping at $28 or more, and leave our Idaho warehouse the same or next business day.
Nothing beats having the exact right test lead the moment troubleshooting starts, built clean and built once. Put two set screws to work and get back to finding the fault.
