It functions as a mounting holder that braces electrical boxes firmly against the interior wall surface during retrofit and remodel installations. The 820-D accommodates walls up to 1.5 inches thick, making it suitable for a range of standard drywall and plaster wall assemblies. Electricians and experienced DIYers install this support when adding new switch or device boxes to finished walls where a stud is not accessible at the desired location.\u003c\/p\u003e\n\u003cp\u003eThis box support is used in residential and light commercial retrofit wiring projects where cutting a new box opening into an existing finished wall is required. It is particularly useful during remodel work, room additions, and outlet or switch relocation jobs. The old work design eliminates the need to open the wall cavity from both sides, speeding up installation in occupied spaces. It is appropriate for use with standard single-gang switch boxes in drywall and similar wall board assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePre-galvanized steel construction for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eSupports switch boxes in old work and retrofit electrical installations\u003c\/li\u003e\n  \u003cli\u003eAccommodates maximum wall thickness of 1.5 inches\u003c\/li\u003e\n  \u003cli\u003eDesigned for use where stud access is not available at the box location\u003c\/li\u003e\n  \u003cli\u003eSpeeds up remodel wiring by eliminating the need for wall cavity access from both sides\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement bracket for standard single-gang switch box installations in old work and retrofit residential or light commercial wiring applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with applicable NEC requirements.
