Ideal Industries B21 B-cap Wire Connector Red 100pk

Product Description

The IDEAL INDUSTRIES B21 is a low-profile twist-on wire connector designed for use in tight, confined spaces where standard connectors do not fit. The B-CAP features slim, classic fins and an expanding interior spring that provides a secure grip with extra leverage on the wire bundle. The flame-retardant shell resists environmental extremes, and a deep skirt delivers maximum dielectric protection to prevent flash-over and reduce the risk from turned-back strands. This model is sold in a box of 100. Electricians reach for the B21 in retrofit work and shallow electrical boxes where clearance is limited.

The B21 B-CAP is well suited for residential and light commercial electrical work, particularly retrofit and upgrade projects where existing junction boxes or device boxes offer minimal depth. The slim profile allows the connector to seat fully inside shallow boxes without the bulk of conventional wire nuts. It is appropriate for general wiring applications handled by licensed electricians and qualified electrical contractors working under NEC guidelines.

Compatibility

Designed as a twist-on wire connector suitable for copper wire combinations ranging from 20 gauge to 6 gauge, with the Red B2 model rated for combinations up to 5 conductors of 12 AWG.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always shut off and verify the absence of voltage at the circuit before making or breaking wire connections. Twist the connector clockwise onto the wire bundle until firm resistance is felt and no bare copper is exposed below the skirt. Do not use on aluminum wiring without confirming connector compatibility with aluminum conductors.
