Flex, AC and MC connectors terminate flexible metal conduit and armoured cable into a box or enclosure knockout. This range covers Arlington SNAP2IT and SNAP-TITE push-on connectors that install without tools, screw-in flex connectors and couplings, two-screw clamp connectors, duplex connectors that take two cables through one knockout, insulated throat versions and 90 degree bodies. Trade sizes run 3/8 inch through 3-1/2 inch. Size by the cable outside diameter range printed on the connector rather than by conductor gauge: the 3/8 inch SNAP2IT retrofit connector, for example, covers a .405 to .605 inch cable range. Maple Electric Supply is an authorized Arlington dealer.
**How do I know a connector fits my MC cable?**
Go by the cable outside diameter range, which Arlington prints on the connector and lists in the product title. The 3/8 inch SNAP2IT retrofit connector covers .405 to .605 inch. Measure the armour across the flats and confirm it falls inside the stated range before you order a case.
**What does the SNAP2IT design actually save me?**
The connector snaps onto the cable and then snaps into the knockout, so there is no locknut to fish behind a panel and no screwdriver work at the box. Retrofit versions come apart again, which matters when a cable has to be pulled back out of an existing enclosure.
**Do I need an insulated throat connector?**
An insulated throat protects conductor insulation where wire leaves the connector. Several models here ship insulated, including the 90 degree SNAP2IT and the 1 inch flex connector. Where the connector is not insulated, an anti-short bushing does the same job. Follow the Canadian Electrical Code for your installation.
**What is a duplex connector for?**
A duplex connector lands two cables in a single knockout, which saves knockouts on a crowded panel or box. The 3/8 inch duplex model here accepts NM, BX, AC and MC. Remember that two cables through one connector still count as two cables when you calculate box fill.
**Do you sell these by the case or individually?**
Both. Several models are listed in packs of 25 or 100 and others are sold single, with the pack quantity stated in the product title. For a quantity not shown, call (905) 553-7171. Free shipping applies to orders over $150 going to Ontario and Quebec addresses.
