{"product_id":"qbp369001","title":"Attwood Marine Snap-Lock 1.77 Seat Base, 7 x 7 in, Stainless Steel","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Attwood Marine SP-69773 is a Snap-Lock 1.77 seat base in stainless steel with a 7 x 7 inch deck plate. It is built for pedestal seat installations that use the 1.77 inch Snap-Lock system, and it gives you a fixed base point for adding a new seat position or replacing a worn base. The plate requires a 2.75 inch mounting hole and about 3 inches of clearance below deck.\u003c\/p\u003e\u003cp\u003eThis base is a practical match for fishing boats, pontoon boats, and cruising layouts where removable pedestal seating makes sense. The stainless plate suits exposed deck areas better than a painted base, and the square footprint spreads load across a wider mounting area than smaller round bases.\u003c\/p\u003e\u003cp\u003eFor fit, the main checks are simple: your pedestal needs to be the 1.77 inch Snap-Lock type, the deck needs room for the 7 x 7 inch plate, and the structure below needs space for the hole and hardware. It is not a universal seat base for every pedestal standard, so matching the seating system matters before you drill or replace an existing mount.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eFits the Attwood Swivl-Eze 1.77 inch Snap-Lock pedestal seating system\u003c\/li\u003e\n\u003cli\u003e7 x 7 inch square base plate in stainless steel\u003c\/li\u003e\n\u003cli\u003eRequires a 2.75 inch mounting hole with about 3 inches of depth below deck\u003c\/li\u003e\n\u003cli\u003eInstalls through the deck with six screws or bolts\u003c\/li\u003e\n\u003cli\u003eSnap-Lock connection and locking clip help keep the pedestal engaged during use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis base is best suited to boats already set up around the 1.77 inch Snap-Lock platform. That makes it useful when you want to move a seat between locations on board, add a second seating point, or replace a damaged base without changing the rest of the pedestal system.\u003c\/p\u003e\u003cp\u003eBefore installation, measure the deck surface and check what sits below it. On many boats, the area under a seat base can share space with rigging, fuel lines, wiring, liners, or storage compartments, so the 2.75 inch cutout and below-deck depth need to be confirmed before mounting.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe square plate mounts through the deck with six fasteners, so the final hold depends on the deck material and the backing method used. On fiberglass decks and aluminum decks alike, a clean cutout and solid support under the mounting area matter more than speed of installation.\u003c\/p\u003e\u003cp\u003eThis is a good fit for owners who want a removable pedestal seat arrangement without changing to another seating standard. It makes sense at the helm, in the cockpit, or at a secondary fishing position where a stable seat base is needed and the pedestal may be removed when the deck needs to stay clear.\u003c\/p\u003e","brand":"Attwood Marine","offers":[{"title":"Default Title","offer_id":52581868273845,"sku":"QBP369001","price":94.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1329206_qbp369001.jpg?v=1780200940","url":"https:\/\/www.qualityboatparts.com\/products\/qbp369001","provider":"Quality Boat Parts","version":"1.0","type":"link"}
