The HAMMOND CWCP4 is a closure plate with knockout designed for use in electrical enclosure applications. Closure plates provide a clean, secure panel termination at enclosure openings, blocking unauthorized access and protecting internal components from contaminants. The knockout feature allows installers to punch or remove a pre-scored section to route conduit, wiring, or fittings without requiring additional drilling or fabrication. This part is typically installed by licensed electricians during panel assembly, enclosure modification, or retrofit work.
The CWCP4 closure plate is suited for use in commercial and industrial electrical enclosure installations where a finished, code-compliant panel opening cover is required. It is commonly used during new construction, equipment upgrades, or enclosure expansions where unused openings must be sealed or adapted for conduit entry. The knockout design reduces on-site labor by eliminating the need for field drilling.
Designed as an OEM-style replacement or accessory closure plate for compatible Hammond electrical enclosures requiring panel-opening coverage with knockout access.
Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the enclosure before beginning any panel work. Use the appropriate knockout punch or removal tool to open the pre-scored section only when conduit or fitting entry is needed. Do not force or bend the plate during installation, as distortion may compromise the enclosure seal.
