Thomas & Betts TB2522 – Frequently Asked Questions

1) What cord diameter will the Thomas & Betts 2522 strain relief connector actually grip?
The 2522 is sized for cord jackets measuring .375 inch to .500 inch in outside diameter. Measure the jacket OD on the cordage, not the conductor size. Anything under .375 inch will not be clamped securely by the grip, and anything over .500 inch will not seat in the body.
2) Will a 1/2 inch cord connector drop into the knockout on my junction box?
Yes. The 2522 is a 1/2 inch trade size connector, so it lands in a standard 1/2 inch enclosure or panel knockout without a reducing washer or adapter.
3) I need a cord grip for a 3/4 inch knockout instead of 1/2 inch - what should I order?
The Thomas & Betts 2522 is a 1/2 inch trade size connector, so it will not land in a 3/4 inch opening without an adapter. For a 3/4 inch hub, the Bridgeport Fittings RSR-2106 aluminum cord grip connector is specified as 3/4 inch NPT and mounts directly in that opening.
4) What is the difference between the Thomas & Betts 2522 cord connector and the Bridgeport Fittings RSR-2106?
They differ in trade size and body material. The Thomas & Betts 2522 is a 1/2 inch trade size straight strain relief cord connector built in zinc die cast, sized for cord diameters of .375 inch to .500 inch. The Bridgeport Fittings RSR-2106 is an aluminum cord grip connector with a 3/4 inch NPT hub. If the enclosure knockout is 1/2 inch, the 2522 drops straight in; a 3/4 inch opening is where the RSR-2106 fits without a reducing washer.
5) Is the Thomas & Betts 2522 metal or plastic?
Zinc die cast, with a metallic finish. That gives you a metal body at the enclosure wall rather than a nylon or plastic grip, which matters on industrial equipment wiring and control panels where the cord entry takes physical abuse.
6) What does a strain relief cord connector actually do that a plain bushing does not?
It clamps the cord jacket at the point of entry so pulling force on the cord is taken by the connector instead of the wire terminations inside the box. A plain bushing only protects the jacket from the knockout edge. The 2522 is built for the clamping job at boxes, panels, and enclosures.
7) Can I use the 2522 on flexible conduit or armored cable?
No. It is a cord connector, built to terminate and protect flexible cordage such as SO or SJO type cable at an enclosure. Flexible metal conduit and armored cable need their own connector designed for that raceway and its armor.
8) Will a 3/4 inch cord grip work as a substitute for the Thomas & Betts 2522 on my control panel?
Not as a direct substitute. The Thomas & Betts 2522 is a straight strain relief cord connector in 1/2 inch trade size, intended for standard 1/2 inch enclosure and panel knockouts. The Bridgeport Fittings RSR-2106 is a 3/4 inch NPT cord grip, so it serves a larger entry rather than replacing the 2522 in a 1/2 inch hole. Confirm the knockout diameter on the panel before ordering either one.
9) What is the exact part number to order for the Thomas & Betts 1/2 inch straight strain relief connector?
Order Thomas & Betts part number 2522. It is a single-model item, so there are no finish or size options to pick, just the 1/2 inch straight zinc die cast body.
