Legrand 77705 4-inch Round Electrical Box 1/2 Inch Deep

Product Description

The LEGRAND 77705 is a 4-inch round electrical box designed for direct-mount installation in residential and light commercial wiring applications. With a shallow 1/2-inch depth, this box suits locations where wall cavity space is limited or where a low-profile mounting solution is required. Electricians use this type of box for ceiling or wall fixture support, junction work, and device mounting where a round form factor meets code. The direct-mount design simplifies rough-in by eliminating the need for a separate mounting bracket.

This box is appropriate for standard rough-in electrical work in wood-frame or similar construction. It fits typical new-construction and retrofit scenarios where a round ceiling or wall box is specified. The 4-inch diameter is a common industry-standard size that accommodates a wide range of cover plates and fixtures. Licensed electricians performing branch-circuit rough-in or fixture installations will find this a straightforward fit for standard residential or light commercial projects.

Key Features

• 4-inch round form factor fits standard round cover plates and fixture canopies

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify with a non-contact voltage tester before beginning work. Secure the box firmly to the structural member before pulling conductors. Do not exceed the cubic-inch fill capacity required by NEC Article 314 for the conductors and devices being installed.
