Arlington Industries 4040A Snap2it Duplex Connector

Product Description

The ARLINGTON INDUSTRIES 4040A is a Snap2It duplex connector designed for fast, tool-free electrical installations. This connector secures nonmetallic sheathed cable or flexible conduit into electrical boxes and panels without the need for separate clamps or locknuts. The snap-in design allows electricians to seat the connector with a single push, reducing installation time on residential and light commercial wiring jobs. It is sold individually and is a standard hardware accessory used wherever quick, secure cable entry is needed.

The 4040A is well suited for residential new construction and retrofit wiring projects where speed and consistency at the box are priorities. Electricians use this connector when terminating cable runs into duplex outlet boxes, junction boxes, or similar enclosures. The snap-in mechanism locks the connector in place without tools, making it practical in tight spaces and high-volume rough-in work. It is a single-unit accessory appropriate for any job requiring clean, code-compliant cable entry.
