Orbit Industries 5SDB-50/75-FB 4-11/16 in Square Box with Bracket

Product Description

The ORBIT INDUSTRIES 5SDB-50/75-FB is a 4-11/16 inch square (5S) steel electrical box welded with a flat bracket and pre-punched knockouts sized for 1/2 inch and 3/4 inch conduit entries. At 2-1/8 inches deep, the box provides adequate volume for device or junction applications where additional wire fill capacity is required. The integrated flat bracket (FB) is factory-welded to the box, allowing for direct mounting to structural members during rough-in. Electricians and electrical contractors install this box in residential and light commercial wiring systems where a larger-capacity square box is needed at outlet, junction, or device locations.

This box is suited for rough-in installations in wood-frame or steel-stud construction where a 4-11/16 inch square box is specified. The welded flat bracket positions the box flush to framing for straightforward drywall or finish-surface alignment. Pre-punched 1/2 inch and 3/4 inch knockouts accept standard EMT, rigid, or flexible conduit connectors, making it compatible with common conduit wiring methods used in residential and commercial electrical work.

Key Features

• 4-11/16 inch square (5S) footprint provides greater wire fill capacity than standard 4 inch boxes
• 2-1/8 inch depth accommodates multiple conductors and device wiring at junction or outlet points
• Factory-welded flat bracket (FB) for direct attachment to framing members during rough-in
• Pre-punched 1/2 inch and 3/4 inch knockouts for flexible conduit entry options
• Welded steel construction for durability in permanent installations

Compatibility

Designed as an OEM-style replacement or standard rough-in component for residential and light commercial electrical installations requiring a 4-11/16 inch square box with a flat bracket mounting configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the work area before beginning box installation or making wiring connections. Secure the flat bracket firmly to the framing member before pulling conductors to ensure box position is fixed prior to finish work. Verify that conduit connectors match the knockout size selected before tightening to avoid damage to the knockout opening.
