Designed to seal or conceal instrument installation holes and access cutouts, it's a simple, low-profile solution that blends into any white deck or console. The plate lifts off easily when you need to access wiring or inspect below-deck components — no tools required for removal.
Molded from UV-stabilized, acetone-resistant polypropylene, this cover plate holds up to sun, salt, and cleaning solvents without fading, cracking, or warping over time. Four #8 fasteners (not included) secure it firmly in place.

Parts Desk Insights
Best use case: This cover plate is the right call when you're filling a pre-cut instrument hole that's no longer in use, or when you want a clean finish over a wiring access point on a console or deck. It's a go-to for console refits and instrument upgrades where old cutouts need to be closed off neatly. The 4-1/8 in. OD fits the most common 2-3/4 in. instrument cutout size. If your hole is larger, see our 39591 or 39601 mounted cover plates. For a lockable or removable access solution, consider a Twist 'N' Lock deck plate instead.
