On Q / Legrand P118R 1-gang 18 Cu in Plastic Box Nail

Product Description

The ON Q / LEGRAND P118R is a single-gang plastic electrical box rated at 18 cubic inches, designed for new-construction rough-in applications in residential and light commercial wiring. The captive nail design allows for fast, one-handed fastening directly to wood studs, reducing install time on framed walls. At 18 cubic inches, the box provides adequate volume for standard device and intercom accessory wiring as required by NEC fill-calculation rules. Electricians and low-voltage installers use this box as a mounting point for switches, receptacles, and intercom accessories during the framing stage of a build.

This box is suited for new-construction wall framing where studs are accessible before drywall installation. The single-gang configuration accommodates one device or decorative plate. It is commonly installed in residential construction projects where intercom accessories, communication devices, or standard wiring devices require a code-compliant enclosure. The captive nails eliminate the need for a separate hammer-and-nail step, making it efficient for high-volume rough-in work.

• Single-gang design fits one wiring device or intercom accessory
• Captive nail mounting system for direct attachment to wood studs during new construction

Compatibility

Designed as an OEM-style new-construction enclosure compatible with standard single-gang wiring devices and intercom accessories requiring an 18 cubic inch plastic box with captive nail mounting.

Installation Notes

Installation is performed by licensed electricians or low-voltage technicians during the rough-in phase before drywall is hung. Nail the box to the stud face at the correct setback depth to finish flush with the finished wall surface per local code. Verify box fill does not exceed 18 cubic inches as calculated under NEC Article 314 before pulling conductors. All work should comply with applicable local electrical codes and the current edition of the NEC.
