It fits a 2 inch diameter mounting hole, uses a 2-1\/2 inch by 2-1\/2 inch face plate, and is made for door or panel thicknesses from 1\/4 inch to 1-1\/8 inch.\u003c\/p\u003e\u003cp\u003eThis series is built with a black or white polymer body, chrome plated zinc alloy, and a stainless steel stem and lock nut. The latch has detents that show the open or closed position, which is useful on board when checking that a locker, compartment, or cabin panel has been secured before getting underway.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eFlush lock format keeps the face plate low on doors, lockers, and access panels where protruding hardware can snag gear or lines.\u003c\/li\u003e\n\u003cli\u003eSupplied with two keys for keyed access control on storage compartments and interior or exterior boat panels.\u003c\/li\u003e\n\u003cli\u003eInstalls in a 2 inch diameter hole and fits door or panel thicknesses from 1\/4 inch to 1-1\/8 inch.\u003c\/li\u003e\n\u003cli\u003e2-1\/2 inch by 2-1\/2 inch face plate gives a clear reference for checking available mounting space before cutting or replacing hardware.\u003c\/li\u003e\n\u003cli\u003ePolymer body with chrome plated zinc alloy hardware and a stainless steel stem and lock nut for use in the marine environment.\u003c\/li\u003e\n\u003cli\u003eDetents indicate the open or closed position, helping the operator confirm latch status at a glance.\u003c\/li\u003e\n\u003cli\u003eAvailable in black or white finishes, with cam bar configurations for different latch reach and panel setups.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThe range varies by finish, cam bar style, cam bar adjustment range, and shipping weight. Black and white finishes are available, with adjustment ranges of 3\/8 inch to 3 inches or 1-1\/16 inches to 2-9\/16 inches depending on the cam bar configuration.\u003c\/p\u003e\u003cp\u003eAcross the series, the shared fit details remain the same: a 2 inch mounting hole, a 2-1\/2 inch by 2-1\/2 inch face plate, and compatibility with 1\/4 inch to 1-1\/8 inch door or panel thickness. The finish should be matched to the surrounding deck, locker, or cabin hardware, while the cam bar option should match the latch reach needed behind the panel.\u003c\/p\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eBefore installation, confirm the panel thickness, the available space behind the mounting surface, and the cam bar reach needed to engage the strike area. The 2 inch mounting hole and square face plate make it a practical replacement candidate when matching existing cutouts, but the cam bar style should still be checked against the original latch geometry.\u003c\/p\u003e\u003cp\u003eThis lock suits boat owners replacing worn locker hardware, adding keyed access to storage compartments, or fitting a flush latch where a cleaner surface is preferred. Common locations include cockpit lockers, cabin storage doors, deck access panels, and other compartments where the mounting surface falls within the stated thickness range.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eRinse the lock with fresh water after saltwater exposure and keep the keyway free of grit, salt, and cleaning residue. During routine boat checks, operate the latch and key to confirm smooth movement, and inspect the stem, lock nut, cam bar, and strike contact point for secure engagement.\u003c\/p\u003e","brand":"Perko","offers":[{"title":"Black \/ 3\/8 to 3 \/ 3.2\/12.5","offer_id":52581970313397,"sku":"QBP138424-V1","price":73.41,"currency_code":"USD","in_stock":true},{"title":"Black \/ 3\/8 to 3 \/ 3.1\/12.1","offer_id":52581970346165,"sku":"QBP138424-V2","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Black \/ 1-1\/16 to 2-9\/16 \/ 3.4\/13.2","offer_id":52581970378933,"sku":"QBP138424-V3","price":0.0,"currency_code":"USD","in_stock":false},{"title":"White \/ 3\/8 to 3 \/ 3.2\/12.5","offer_id":52581970411701,"sku":"QBP138424-V4","price":0.0,"currency_code":"USD","in_stock":false},{"title":"White \/ 3\/8 to 3 \/ 3.1\/12.1","offer_id":52581970444469,"sku":"QBP138424-V5","price":0.0,"currency_code":"USD","in_stock":false},{"title":"White \/ 1-1\/16 to 2-9\/16 \/ 3.4\/13.2","offer_id":52581970477237,"sku":"QBP138424-V6","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334815_qbp138424.webp?v=1780201906","url":"https:\/\/www.qualityboatparts.com\/products\/qbp138424","provider":"Quality Boat Parts","version":"1.0","type":"link"}
