Thomas & Betts 3312-TB – Frequently Asked Questions

1) Will the 3312-TB fit a 1/2 inch knockout in a standard steel box?
Yes. It's built for a 1/2 inch knockout, which is the most common knockout size in standard device and junction boxes, so it drops straight in and takes a locknut on the inside.
2) Two-screw connector or squeeze connector for flex, which should I use?
The two-screw type, like the 3312-TB, clamps the cable with a pair of set screws and is the usual choice for AC/MC and flexible metal conduit where you want a positive grip you can re-tighten. A squeeze (saddle) connector uses a clamp and one screw and is generally faster on longer runs. Both land in the same 1/2 inch knockout at 1/2 inch trade size, so the choice is about how you want to grip the cable, not about box prep.
3) Is the Thomas & Betts 3312-TB steel or die cast?
Steel, with a metallic finish. A steel body keeps the equipment grounding path continuous through the fitting when the armor is properly seated, which is what an inspector looks for on an AC or flex termination.
4) What part number do I order to standardize 1/2 inch AC cable connectors across a building?
Order Thomas & Betts part 3312-TB. It's a single catalog number covering the 1/2 inch two-screw connector, so a facility or MRO buyer can spec one line item for every 1/2 inch armored cable termination instead of mixing brands box to box.
5) Does the 3312-TB come with a locknut?
The 3312-TB is the two-screw connector body itself at 1/2 inch trade size. Plan on the locknut and any required insulating bushing as separate line items when you write the order, along with enough connectors for both ends of each whip.
