The 4\" black plate includes a standard trim ring that covers the mounting flange for a finished appearance, and the smooth lid surface keeps the profile clean and snag-free.\u003c\/p\u003e\u003cp\u003eA self-aligning center makes it easy to engage the thread without having to look, and the gasket compresses against an innovative sealing surface to create a watertight fit. A secondary back-up sealing wall provides an additional layer of water resistance even if the gasket is ever removed or damaged.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e4\" screw-out closure with single-start, non-jamming buttress thread\u003c\/li\u003e\n\u003cli\u003eSelf-aligning center for easy, tool-free engagement\u003c\/li\u003e\n\u003cli\u003eInnovative gasket design for a watertight seal\u003c\/li\u003e\n\u003cli\u003eBack-up sealing wall provides secondary water resistance\u003c\/li\u003e\n\u003cli\u003eStandard trim ring included — covers mounting flange for a clean finish\u003c\/li\u003e\n\u003cli\u003eSmooth lid surface\u003c\/li\u003e\n\u003cli\u003eBlack finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBest Use Cases\u003c\/h3\u003e\u003cp\u003eThe Beckson screw-out is the right choice for deck plate locations where cross-threading is a recurring problem — the buttress thread design eliminates it. Well suited for fuel sender access, inspection ports, and wiring pass-throughs that are serviced regularly. The 4\" size fits tighter deck spaces where a 6\" or 8\" plate won’t fit. Choose black to match dark-coloured decks or hardware.\u003c\/p\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe 4\" measurement refers to the plate’s outer diameter — confirm your cutout size before ordering, as the required hole diameter will be smaller than the OD.
