Thomas & Betts 2940AL – Frequently Asked Questions
1) What hub size does the Thomas & Betts 2940 cord connector thread into?
It threads 1 inch NPT, so it lands in a 1 inch threaded hub, a 1 inch locknut-and-bushing opening, or a tapped boss on an enclosure or bulkhead. The thread is tapered pipe thread (NPT), not metric or PG, so don't plan on it mating with a metric gland hole.
2) Aluminum or nylon 2940 cord grip, which should I order?
The 2940 comes two ways: 2940AL in aluminum and 2940NM in nylon. Aluminum is the pick where the gland takes mechanical abuse or where you want a metallic path consistent with a metal enclosure. Nylon is non-metallic and non-corroding, which suits washdown, coastal, or chemical-exposure spots. Both carry the same 1 inch NPT thread and the same strain relief, so the body material is the only decision.
3) Is the Thomas & Betts 2940 cord grip approved for hazardous locations?
Only in the narrow case the NEC allows. The 2940 is suitable for hazardous locations where general purpose equipment is specifically permitted by NEC 501-4(b). It is not an explosionproof gland, so for a Class I Division 1 seal you need a listed hazardous-location fitting instead.
4) What is the closest alternative to the Thomas & Betts 2940 straight cord connector for a 3/4 inch hub instead of 1 inch?
The Thomas & Betts 2940 is built for a 1 inch NPT opening, so it will not thread into a 3/4 inch hub. For that opening, the Bridgeport Fittings RSR-2106 is an aluminum cord grip connector with a 3/4 inch NPT thread. Both are straight cord connectors that pass a cord into an enclosure through a threaded hub, so the choice comes down to matching the hub size you actually have.
5) Is the Bridgeport RSR-2106 a direct substitute for a Thomas & Betts 2940AL?
Not a direct swap. Both are aluminum straight cord grip connectors, but the Bridgeport RSR-2106 is a 3/4 inch NPT fitting while the 2940AL carries a 1 inch NPT thread. They are interchangeable only in function, not in hub size, so a 1 inch knockout or hub needs the 2940AL unless you add a reducing bushing.
6) Does this cord connector hold the cable so the conductors don't take the pull?
It does. The 2940 is built with strain relief, and the gland nut is designed to restrict cable bending right at the entry, so flexing and tension are taken by the grip and not by the terminations inside the box. Thomas & Betts describes it as an extended cable range with superior strain relief.
7) I need a 3/4 inch cord grip, not 1 inch. What else do you carry?
The 2940 is a 1 inch NPT body only. For a 3/4 inch hub, the Bridgeport Fittings RSR-2106 is an aluminum cord grip connector with 3/4 inch NPT threads.
8) How are the 2940 cord connectors packaged for a stocking order?
They ship 10 to an inner carton and 100 to the outer, so a full master carton is 100 pieces. Useful if you're standardizing cord entries across a plant or multi-family retrofit and buying by the case.
