The ABB A243D is a one-piece threaded male adapter designed for use with Electrical Nonmetallic Tubing (ENT) systems. It provides a secure, threaded connection point where ENT conduit interfaces with a knockout or fitting entry. Sized at 1/2 inch with a length of 1.406 inches, this adapter is molded from polycarbonate for durability and resistance to corrosion and impact. Electricians rely on this adapter to transition ENT conduit into enclosures, panels, and junction boxes in a clean, code-compliant manner. This listing includes a pack of 150 units, suitable for larger jobs or ongoing service inventory.
The A243D is used in residential and light commercial electrical installations where ENT conduit is routed through walls, ceilings, and conduit runs that terminate at an enclosure. The threaded design allows the adapter to secure into standard knockout openings, creating a stable entry point. It is well suited for new construction wiring projects and renovation work where ENT is the specified raceway system. The polycarbonate construction makes it appropriate for indoor dry and damp location applications.
Designed as an OEM-style replacement and standard-use adapter for 1/2 inch ENT conduit systems in residential and light commercial electrical applications.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and panel before making any connections at an enclosure knockout. Hand-tighten the threaded adapter into the knockout opening and verify a secure fit before pulling conductors. Avoid over-tightening, which can crack the polycarbonate body.
