A wireway routes and protects wiring and cables. They often install as systems and may connect with multiple other wireways to create long runs with straight sections and other fittings to form a pathway. They may also work with fittings to create more complicated runs around corners or sharp turns. Wireways include hinged or removable covers to protect wiring and cables while still allowing access. E-Box wireways include a NEMA 1 rating, which means they help protect against falling dirt or dust and can only see use indoors. Wireways may come with or without knockouts. Options that include knockouts work well in areas with a standard configuration. This means they don’t require customization or extra setup. Wireways without knockouts can work for custom setups or configurations as this allows you to best determine where to place the knockouts to suit the job.
