Perko Deck Plate Key – Black Plastic, Fits 1-1/4" & 1-1/2" Slot-Type Deck Plates
A purpose-fit deck plate key designed specifically for Perko 1-1/4" and 1-1/2" slot-type deck plates, as well as other slot-type deck plates sharing the same lug geometry. The precise 1-1/8" center-to-center lug spacing and 1" spade length ensure a clean, secure engagement with the cap — protecting the deck plate lugs from the rounding and wear that can result from using an ill-fitting or universal key over time.
- Fits Perko 1-1/4" and 1-1/2" slot-type deck plates — purpose-matched to Perko’s slot-type hardware family
- Also fits other slot-type deck plates with 1-1/8" center-to-center lugs and 1" spade length
- Black plastic construction — lightweight, non-sparking, and corrosion-proof; safe for use near fuel fills
- Compact and lightweight — 18g; stows easily in a tool bag, tackle box, or alongside the deck plate hardware
Parts Desk Insights
Best use case: This is the correct key to specify when a customer owns Perko slot-type deck plates and wants the matched tool rather than a universal key. The precise lug fit protects the deck plate cap from wear, which matters on quality fittings that are opened and closed regularly — such as access plates over battery compartments, storage lockers, or fuel fills. The non-sparking plastic construction also makes it the safer choice near gasoline fuel fills compared to a metal key. It’s a practical spare to keep permanently stored near the deck plate it serves, rather than in a general tool kit.
