Thomas & Betts 316 3 TITE-BITE CONNECTOR NON-INSUL

The Arlington Industries 380ST SNAP2IT is a snap-in MC/AC cable connector sized for 3/8 inch cable and sold in packs of 100. The difference is the installation method and body: the Thomas & Betts 316 is a malleable iron Tite-Bite connector, while the 380ST snaps into the knockout rather than using a locknut. For large repetitive runs where the same 3/8 inch cable terminates into standard knockouts, the snap-in style is the quicker termination; for a metal-bodied iron fitting, the 316 is the one to stay with.

For that specific combination, look at the Arlington Industries 407AST SNAP2IT, which is built for a 3/4 inch knockout with 3/8 inch cable and comes in packs of 100. The Thomas & Betts 316 is a Tite-Bite style AC/MC/flex connector in malleable iron and is not matched to that knockout-to-cable pairing, so confirm the box opening before ordering.

Malleable iron, with a metallic finish. Malleable iron gives it more resistance to being cracked or crushed during pull-in than a die-cast body, which matters on commercial and MRO work where connectors get handled roughly in a panel.

Two different installation methods. The Thomas & Betts 316 is a Tite-Bite style connector in malleable iron that clamps the cable mechanically. Arlington's SNAP2IT connectors, like the 380ST for 3/8 inch MC/AC cable or the 407AST with a 3/4 inch knockout for 3/8 inch cable, snap onto the cable and into the knockout without tightening a screw, which is faster on high-count installs. The Arlington items are sold in packs of 100.

No - neither is a match for an insulated-throat callout. The Thomas & Betts 316 is specifically a non-insulated Tite-Bite connector, and the Arlington 380ST and 407AST are SNAP2IT series snap-in cable connectors. If the drawing requires an insulated throat, none of these three satisfy it and you need a connector specified as insulated.
