The LEGRAND WP3455-LA is a blank outlet insert designed to cover unused outlet openings in structured wiring and low-voltage wall plates. This insert snaps into compatible ON-Q and LEGRAND plate systems, providing a clean, finished appearance wherever a port is not needed. It is a common finishing component used during new construction, remodel work, and low-voltage system installations. Electricians and low-voltage installers use this part to maintain a professional panel appearance and keep dust and debris out of open wall plate ports.
This blank insert is typically installed in residential and light commercial settings where structured wiring enclosures, media panels, or decorator-style wall plates have unused port positions. It fits into standard ON-Q and LEGRAND outlet plate openings. It is well suited for home theater rough-ins, data distribution panels, and any installation where not all plate ports are in active use at time of completion.
Designed as an OEM-style insert for ON-Q and LEGRAND structured wiring wall plates and decorator-style outlet plate systems that accept standard snap-in inserts.
This insert is installed by low-voltage technicians or electricians as part of a wall plate finishing process. No tools are typically required for snap-in installation. Ensure the wall plate is secured and any active circuits in adjacent ports are de-energized before working in close proximity to live connections. Follow applicable NEC guidelines for low-voltage wiring installations.
