Arlington Industries MCCC SNAP2IT Insulated-Throat Zinc Die-Cast AC/MC/Flex Connector

Arlington Industries' MCCC SNAP2IT cable connector is a zinc die-cast, insulated-throat fitting built for fast, code-compliant terminations of AC, MC, and flexible conduit cable. The SNAP2IT platform spans 3/8", 1/2", and 3/4" knockout sizes in single and duplex configurations, accepting cable outside diameters from .370" to .820" so one connector family covers commercial, industrial, and residential rough-in work. Every MCCC connector is cULus and CSA listed and manufactured in the USA.

Key Features

  • Trade Size Range: 3/8", 1/2", and 3/4" knockout sizes covering single connectors (3/8" and 1/2") and duplex connectors (1/2" and 3/4") for full job coverage.
  • Durable Zinc Die-Cast Construction: Zinc die-cast body delivers corrosion resistance and long-term durability in demanding electrical environments.
  • SNAP2IT Snap-In Installation: Arlington's tool-free snap-in system seats the connector in one motion, eliminating loose parts and speeding up rough-in.
  • Insulated Throat: Protects cable insulation at the point of entry, reducing abrasion risk and meeting NEC requirements for insulated connectors.
  • Single & Duplex Configurations: Duplex models pull two cables through a single knockout, saving valuable box real estate on dense panels.
  • Cable Range: Accommodates cable outside diameters from .370" - .510", .405" - .610", .580" - .780", and .590" - .820" depending on connector size.

Arlington Industries 4010AST – Frequently Asked Questions

1) What size knockout do Arlington SNAP2IT insulated throat cable connectors fit?
The SNAP2IT insulated throat line covers three knockout sizes. Singles snap into 3/8 inch and 1/2 inch knockouts (3810AST for 3/8 inch, 4010AST and 5010AST for 1/2 inch). Duplex versions go in 1/2 inch (404010AST) and 3/4 inch (505010AST) knockouts. Pick by the knockout you have in the box or panel first, then by cable OD, because the same 1/2 inch KO is offered in two different cable ranges.
2) What cable diameter range do the Arlington SNAP2IT AST connectors accept?
Cable OD decides the model. The 3810AST takes .370 to .510 inch. The 4010AST takes .405 to .610 inch. The 5010AST takes .580 to .780 inch, which is the one for larger MC. Duplex 404010AST takes two cables at .405 to .610 inch each, and duplex 505010AST takes two at .590 to .820 inch each. Measure the jacket OD of the cable you are terminating and match it into one of those windows; a cable under the low end will not clamp reliably.
3) I have two MC cables and only one knockout left in the box. What connector do I use?
That is what the duplex SNAP2IT connectors are for. The 404010AST pulls two cables of .405 to .610 inch through a single 1/2 inch knockout, and the 505010AST pulls two of .590 to .820 inch through a single 3/4 inch knockout. Each cable gets its own insulated throat and its own snap clamp, so you get two terminations out of one hole instead of drilling or punching another.
4) Both the 4010AST and 5010AST are 1/2 inch KO. What is the difference?
Same knockout, different cable window. The 4010AST clamps .405 to .610 inch cable; the 5010AST clamps .580 to .780 inch. So on a 1/2 inch knockout you choose by the outside diameter of the AC or MC you are landing, not by the hole. If you are running a mix on one panel, the two overlap only between .580 and .610, so measure rather than assume one covers the job.
5) Do Arlington SNAP2IT connectors need a locknut or any tools to install?
No locknut and no tools. The SNAP2IT body snaps into the knockout in one motion and holds itself there, so there are no loose parts to drop into a live panel and nothing to tighten from inside the box. That is the practical reason electricians spec them for dense panel work: the install is done from the outside of the enclosure.
6) Does the insulated throat on these connectors satisfy the NEC requirement for an insulated connector on MC cable?
The insulated throat is built into the connector body, so no separate bushing is needed at the cable entry. It protects the conductor insulation where it passes into the box and meets NEC requirements for insulated connectors. Every version in the AST line, single and duplex, has it.
7) Are Arlington SNAP2IT connectors metal or plastic, and will they hold up in a damp mechanical room?
Zinc die-cast body, not plastic. Zinc gives you the mechanical durability for repeated panel work plus corrosion resistance in the kind of environments where fittings sit for decades. The only non-metal part is the insulated throat at the cable entry.
8) Can I use SNAP2IT AST connectors on flexible conduit, or are they only for AC and MC cable?
They work for AC cable, MC cable, and flexible conduit terminations at equipment knockouts. The selection is still driven by outside diameter, so match the flex OD to one of the ranges: .370 to .510, .405 to .610, .580 to .780, or the duplex ranges. If the flex measures outside every one of those windows, this is not the fitting for it.
9) Are Arlington SNAP2IT connectors made in the USA?
Yes, the SNAP2IT cable connectors are manufactured in the United States. That matters on public and institutional jobs where domestic sourcing is written into the specification, and it is a common reason procurement standardizes on this line for restocking.
