The L H Dottie Co HPD1732 is a 1-7/32-inch push button knockout designed for use in electrical enclosures, panels, and junction boxes. Push button knockouts allow electricians and electrical contractors to create clean, precise openings in metal enclosures without the need for knockout punches or additional tooling. The HPD1732 is sized at 1-7/32 inches, making it suited for conduit entries or accessory fittings that require a finished, burr-free opening in standard gauge enclosure walls. Sold individually, this is a practical hardware accessory for panel builds and service work.
This knockout is typically used in residential, commercial, and light industrial electrical work where pre-punched or field-punched enclosure openings are required. Electricians use push button knockouts during panel installation, enclosure assembly, and retrofit work when adding conduit connections or fittings to existing boxes. The 1-7/32-inch size accommodates common conduit or connector fittings at that diameter.
Designed as an OEM-style replacement and field hardware accessory for standard metal electrical enclosures and junction boxes requiring a 1-7/32-inch knockout opening.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits and confirm the panel or enclosure is fully powered down before removing knockouts or working inside any electrical enclosure. Use appropriate hand tools to depress and remove the knockout cleanly, and inspect the opening edge for burrs before installing any conduit connector or fitting.
