Carlon BH525A-UPC Ceiling Electrical Box Ul Listed

Product Description

The CARLON BH525A-UPC is a SuperBlue hard body ceiling electrical box designed for residential and light commercial wiring installations. Built from a high-impact polymer compound, this box resists flexing, holds its shape under mechanical stress, and will not crack or shatter on impact — including direct hammer strikes. It serves as a direct substitute for traditional fiberglass electrical boxes. Licensed electricians install this box in new construction and retrofit ceiling applications where durability and code compliance are required. The UL listing confirms it has been independently tested and meets applicable safety standards.

This ceiling box is suited for standard ceiling outlet installations including light fixtures and ceiling fan rough-in work. Its rigid construction makes it well-suited for job sites where boxes are subject to rough handling during the framing phase. The direct fiberglass-substitute design allows it to drop into existing workflows without special hardware or adapters. It is sold individually and is appropriate for both residential construction and light commercial applications where a durable, code-compliant ceiling box is needed.

Key Features

• SuperBlue hard body construction resists impact, flexing, and deformation under extreme conditions
• Will not crack or break when struck with a hammer during rough-in
• Direct substitute for fiberglass electrical boxes — no special adapters required
• UL listed for compliance with applicable electrical safety standards

Compatibility

Designed as an OEM-style replacement and direct substitute for standard fiberglass ceiling electrical boxes in residential and light commercial applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage before beginning any wiring work. Secure the box firmly to the ceiling framing member or approved hanger bar before pulling and terminating conductors. Do not exceed the box fill calculations as required by NEC Article 314.
