It fits doors from 1\" to 1-3\/8\" thick, with a 2-3\/4\" x 2\" case and a 4-3\/8\" x 1-1\/4\" escutcheon, making it a practical fit check for cabin doors, heads, companionway-adjacent doors, and interior boat cabinetry where lockable access matters.\u003c\/p\u003e\u003cp\u003eThe set uses chrome plated zinc alloy and locks from the inside with a turn button or from the outside with a key. During installation, the bevel can be reversed, which helps the lock work with different door swing arrangements without changing the main hardware style.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eMortise lock set with bolt for marine door and cabin hardware applications.\u003c\/li\u003e\n\u003cli\u003eFits door thicknesses from 1\" to 1-3\/8\", a key measurement to confirm before cutting or replacing existing hardware.\u003c\/li\u003e\n\u003cli\u003eChrome plated zinc alloy construction gives the lock set a polished finish suited to visible cabin and cockpit-adjacent installations.\u003c\/li\u003e\n\u003cli\u003eInside turn button and outside keyed operation support privacy and controlled access from either side of the door.\u003c\/li\u003e\n\u003cli\u003eReversible bevel helps the installer adapt the lock during installation for inward or outward opening doors.\u003c\/li\u003e\n\u003cli\u003eUses #6 screws, useful when matching existing fasteners or planning a clean replacement.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eThis is a mortise-style lock, so the door needs a prepared pocket for the case rather than a simple face-mounted latch installation. For a replacement job, compare the existing cutout, case size, escutcheon footprint, and door thickness before ordering. For a new installation, careful layout matters because the escutcheon and face alignment affect both the look of the finished door and how cleanly the bolt engages.\u003c\/p\u003e\u003cp\u003eThe reversible bevel is helpful on boats where door swing direction and frame geometry can vary from one cabin to another. Dry-fitting the lock, checking the swing, and confirming bolt engagement before final fastening will usually save time and prevent binding.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis lock set makes sense for boat owners replacing worn cabin hardware or fitting out a door that needs keyed access from the outside and privacy control from the inside. It is most relevant for interior or protected locations where a chrome plated mortise lock matches the surrounding marine hardware and where the door thickness falls within the specified range.\u003c\/p\u003e","brand":"Perko","offers":[{"title":"Default Title","offer_id":52581875908789,"sku":"QBP951512","price":226.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1330414_qbp951512.webp?v=1780201010","url":"https:\/\/www.qualityboatparts.com\/products\/qbp951512","provider":"Quality Boat Parts","version":"1.0","type":"link"}
