It’s a straightforward, molded PVC option that supports durable installation in standard conduit vaults. Caution: ensure correct fit for non-standard wall depths to avoid loose ends.
Approved Vendor B00821 Bell End Conduit Elbow, 2 in Trade
Best for compact PVC runs where a bell end elbow properly seals a 2-inch conduit. This option suits installations requiring a pivot point at the end of a conduit run. Better for tight spaces than larger end bells, but confirm compatibility with your conduit type. Caution: product naming indicates an elbow rather than a straight end bell, so use in appropriate configurations.

Selected for 1-1/2-inch Carlon PVC runs, this end bell offers PVC construction with precise dimensions (approximately 2.255 Inch Dia x 1.894 Inch). It’s a good choice where space is moderately constrained, and a standard 1-1/2 inch end cap is required. Best for installations prioritizing a snug, durable seal in Carlon systems. Caution: ensure exact trade size to avoid fit issues.
Thomas & Betts E997G-CAR Gray PVC End Bell 1-1/4 Inch Carlon®
Best for smaller diameter PVC conduits, this end bell suits 1-1/4 inch Carlon runs. It provides a compact, durable end-cap solution with PVC construction and standard Carlon sizing. Better for tight installations where space is a premium. Caution: confirm notch alignment with conduit height to ensure full coverage.
Thomas & Betts Carlon E997N Rigid PVC 4 In End Bell
Chosen for rigid PVC 4-inch systems, this end bell is well-suited for larger vaults and longer runs where a sturdy termination is needed. It accommodates larger conduit diameters with a clear PVC construction, offering a secure seal. Limitation: larger footprint may not fit compact wall cavities without planning. Best for standard 4-inch end termination in Carlon PVC networks.
Cantex CTX 2-1/2 PVC END BELL, 5144009
Best for 2-1/2 inch conduit runs, this gray end bell provides protection for wires pulled through vault walls. It’s a mid-range solution balancing size and protection. Choose this if your project requires medium-size conduit termination with vault protection. Caution: verify that wall cavity space can accommodate the 2-1/2 inch end bell’s dimensions.
Buying Guide: Key Purchase Considerations
- Trade size compatibility: End bells come in a range of sizes. Match the trade size to your PVC conduit to ensure a proper seal and protection.
- Material and construction: PVC end bells vary in molded versus rigid constructions. Choose based on space, exposure, and durability needs.

- System compatibility: Some end bells are labeled for Carlon or other Carlon-compatible PVC systems. Confirm your conduit brand to avoid fit issues.
- Installation space: Larger end bells require more cavity depth. Measure available space before ordering.
- Protection level: The primary purpose is protecting conductors during pulls. Evaluate whether the end bell provides sufficient edge protection and a smooth interior surface.
