RACO ProReady Electrical Prefabrication
February 3, 2026
Prefabrication, or prefab, is the future of the commercial construction industry. Electrical contractors can preassemble electrical components in the shop before sending them to jobsites. ProReady™ products and assemblies make it easy. No further prep needed on site. It saves time, materials, and money.
Assembling components under controlled conditions helps you ensure quality control. Shipping assemblies to the jobsite reduces labor costs for both rough-in and trim-out stages of a project.
Benefit with RACO ProReady products:
- Lower material and jobsite labor costs
- Assembling components and wiring devices off-site maintains quality control
- Finish the rough-in phase of the job faster
- Minimizes jobsite packaging waste and scrap, clean up time, and theft
The unique installation efficiency of ProReady™ components save you time. Increase productivity in the shop or on the jobsite. Perfect for projects with repetitive wiring installs.
