Thomas & Betts 2671 Cord Connectors-Straight

The 2671 grips cord from 0.125 to 0.275 inch outside diameter (3.175 to 6.985 mm). Measure the jacket OD of the cord, not the conductor gauge. Anything thinner than 0.125 inch will not be clamped by the segmented chuck, and anything over 0.275 inch will not pass through, so step up to a larger cord grip in those cases.

It has a 3/8 inch NPT male thread, 11.90 mm long. That lands it in a 3/8 inch threaded hub, box opening, or fitting. For a 3/4 inch NPT opening you would need a different grip, such as the Bridgeport Fittings RSR-2106 aluminum cord grip connector in 3/4 inch NPT, or a reducing bushing.

The Thomas & Betts 2671 straight cord connector is built with a 3/8 inch NPT thread, so it will not thread into a 3/4 inch hub. For a 3/4 inch NPT opening, the Bridgeport Fittings RSR-2106 is an aluminum cord grip connector with 3/4 inch NPT threading. Confirm the cord outside diameter against the grip range before ordering, since the two connectors clamp different cord sizes.

It is a nonmetallic grip molded in polyamide (nylon), black. That makes it a reasonable pick where corrosion is a concern and where you do not need a metal body for bonding. If the job calls for a metal cord grip, an aluminum body option like the Bridgeport Fittings RSR-2106 is the other route.

Operating range is -34 to +105 degrees C. That covers unheated outdoor and cold storage service at the low end and hot equipment enclosures, motor terminal boxes and luminaire feeds at the high end. Confirm the cord jacket itself is rated at least as high as the ambient you are installing into.

The body uses a segmented chuck that clamps around the jacket for high mechanical pullout performance without cutting or damaging it. That is the point of using a cord grip rather than a plain bushing on a pendant drop, portable equipment feed, or a hanging control station where the cord takes repeated tugging.

The Thomas & Betts 2671 straight cord connector is suitable for hazardous locations where general purpose equipment is specifically permitted by the NEC, covering Class I Div 2, Class II Div 1 and 2, and Class III Div 1 and 2, and it meets Coast Guard CG293. It carries UL E13938 and CSA. The Bridgeport Fittings RSR-2106 is an aluminum 3/4 inch NPT cord grip connector, which is the option to look at when the hub is 3/4 inch NPT.

The Thomas & Betts 2671 straight cord connector has a plastic body, specifically polyamide (PA), in black. If the job calls for a metallic body, the Bridgeport Fittings RSR-2106 cord grip connector is aluminum. Note that the RSR-2106 is threaded 3/4 inch NPT, so it is an alternative only where the hub accepts that thread size.

Yes. The 2671 packs 25 per inner carton and 250 per outer, running about 2.5 lbs per 100 pieces. Useful if you are standardizing a facility on one 3/8 inch grip size and want shelf stock rather than onesie orders.
