Buying Guide
Key considerations when choosing end bells for PVC conduit:
- Trade size compatibility: match the end bell to your conduit diameter (1-1/4″, 1-1/2″, 2″, 4″, etc.).
- Material and finish: PVC end bells provide corrosion resistance and compatibility with standard PVC systems; verify color and finish compatibility with existing components.
- Application context: choose larger, rugged end bells for vault walls or high-diameter runs; select compact options for tight spaces and elbows.
- Brand and compatibility: Carlon®-style end bells are designed for Carlon systems but often work with similar PVC fittings; confirm fit before combining brands.
- Installation considerations: ensure the end bell’s dimensions do not obstruct internal wiring or hinder future pulls through the conduit.
