ENT terminal adapter · 3/4 in trade size · threaded PVC connector with lock nut · Royal RKTA15
What this product is for
This 3/4 in trade size ENT terminal adapter is used to terminate electrical non-metallic tubing (ENT/Corline) to a box, enclosure, or fitting with a threaded connection. It provides a clean transition point and is supplied with a lock nut for fastening through a knockout.
Use for
Use for 3/4 in ENT raceway runs in concrete slabs, fire-rated interior wall assemblies, and direct-burial ENT systems where the tubing needs to connect to a box or enclosure. Suitable where a non-metallic, corrosion-resistant fitting is preferred.
Avoid for
Avoid using this fitting with conduit types other than compatible 3/4 in ENT, or where a different connector style is required by the box, hub, or site conditions. Confirm compatibility with the raceway system and local electrical code before installation.
Best for
Best for electricians and contractors installing Royal/Westlake ENT systems and needing a standard threaded termination fitting with included lock nut. A practical choice for Corline installations where lightweight PVC fittings help simplify handling on site.
Installed in
Typically installed in residential, commercial, and institutional rough-in work, including slab pours, wall cavities, and below-grade raceway layouts. ENT systems of this type are commonly used where cable pulling and non-metallic corrosion resistance are important.
Why this product exists
This adapter exists to connect 3/4 in ENT to a threaded termination point at a box or enclosure while maintaining a secure mechanical connection. The included lock nut helps complete the termination without needing a separate matching nut.
Compared with similar products
Compared with snap-in or quick-connect ENT fittings, a threaded terminal adapter is typically chosen when terminating through a knockout and securing the fitting with a lock nut. Compared with metallic fittings, PVC fittings are commonly selected where corrosion resistance and compatibility with non-metallic ENT systems are priorities.
