Step-Up Pull Box Extender Step-Up Type 1 pull box extenders allow you to increase the wire capacity of an installation without removing the existing pull box, saving you time and money. Additionally, extenders reduce the need for custom pull box sizes during installation. This new standard is available today or tomorrow, through a local distributor, versus 5–10 days from a local fabricator.
The Pull Box Extender, or “Step-Up”, product is designed to be used in commercial and general industrial applications that previously required a custom sized pull box, or to create additional wiring space for existing pull box installations.
