Thomas & Betts 4921 – Frequently Asked Questions
1) What cord diameter range does the Thomas & Betts 4921 cord connector clamp?
The 4921 strain relief connector grips cord with an outside diameter of .31 to .56 inches. Measure the jacket OD of the cord you're running, not the conductor size, since the clamp seals on the jacket. Cord outside that band won't clamp properly and you'd need a different grip size.
2) What hub size is the Thomas & Betts 4921 strain relief connector?
It's a 1/2 inch trade size fitting, so it lands in a 1/2 inch knockout or threaded hub on a box, fixture, or enclosure.
3) Why would I use a 45 degree cord connector instead of a straight one?
The 4921 is a 45 degree angle cord grip. You use it when the cord has to leave the box on a slant instead of straight out, typically to keep the drop clear of an obstruction or to cut the bend radius stress where a straight fitting would force a sharp kink right at the strain relief. If the cord can run straight out of the enclosure, a straight-body cord connector is the simpler fitting.
4) Is the 4921 cord grip metal or plastic?
Malleable iron body with a metallic finish. That's the choice for industrial and wet-location work where a nylon grip would get cracked by impact or heat, and it gives you a metal path through the fitting rather than an insulating one.
5) Will the Thomas & Betts 4921 work for a liquid tight cord entry on portable equipment?
It's a liquidtight strain relief cord connector in a 1/2 inch size, built for cord entries where the jacket has to be both sealed and mechanically held, such as machine feeds, pendant drops, and portable equipment. The clamp carries the pulling load so the terminations inside the box aren't taking tension. Cord OD has to fall in the .31 to .56 inch range for the seal to close on it.
6) Do I order the 4921 in different sizes or is it one part?
The 4921 is a single part number, one configuration: 1/2 inch hub, 45 degree body, .31 to .56 inch cord range. There are no finish or size options to specify. If your cord is fatter or thinner than that band, you're looking for a different number in the series rather than an option on this one.
