{"product_id":"qbp748840","title":"Attwood Marine 278 ProGlide Seat Mount with Slider, For 2-7\/8 in Posts, Long Handle","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Attwood Marine 278 ProGlide Slider is a boat seat mount with an integrated slide, built for helm and cockpit seating that needs fore and aft adjustment on a 2-7\/8 in pedestal post.\u003c\/p\u003e\u003cp\u003eThis 278 ProGlide setup gives the seat a wider support interface and a smoother adjustment path, which matters when the seat is used at the helm, on a fishing deck, or in a pontoon seating position where the operator may need to move closer to the wheel, controls, or console. The long handle folds out of the way when it is not being used, helping keep the seating area clear.\u003c\/p\u003e\u003cp\u003eThe range includes 0 degree and 3 degree mount angle versions, so the mount can be matched to the seating position and the way the seat needs to sit on the pedestal. Before installation, confirm the existing post diameter, seat mounting pattern, and under-seat clearance on the boat.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eIntegrated seat mount and slider for fore and aft seat adjustment at the helm, cockpit, or fishing station.\u003c\/li\u003e\n\u003cli\u003eFits 2-7\/8 in diameter pedestal posts used in compatible Attwood Swivl-Eze 278 seating systems.\u003c\/li\u003e\n\u003cli\u003eAvailable in 0 degree and 3 degree mount angle versions to match the seating layout.\u003c\/li\u003e\n\u003cli\u003eWider seat interface helps support larger helm seats and keeps the seat connection stable during normal boat motion.\u003c\/li\u003e\n\u003cli\u003eLong release handle folds away when not in use, reducing interference under the seat.\u003c\/li\u003e\n\u003cli\u003eUseful for replacing an existing 278 ProGlide slider or setting up a new marine seat installation where slide adjustment is required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis product is offered in two configurations that share the same 278 ProGlide slider purpose but differ by mount angle.\u003c\/p\u003e\u003cp\u003eThe key difference is the seat mount angle. Both variants are intended for 2-7\/8 in pedestal post applications, but the selected angle should match the existing seating geometry and the way the seat is meant to sit on the boat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e278AOZPGL-1, Mount angle 0 degree. This version keeps the seat mount level, making it a straightforward match for installations where the current seat position does not require tilt correction.\u003c\/li\u003e\n\u003cli\u003e278AO3PGL-1, Mount angle 3 degree. This version adds a 3 degree mount angle, which can help match seating setups where the seat base needs a slight tilt relative to the pedestal.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eCheck that the boat uses a compatible 2-7\/8 in pedestal post before ordering. The slider sits between the seat and pedestal system, so it is also important to confirm the bolt pattern on the seat bottom and the available space under the cushion for the slide mechanism and handle movement.\u003c\/p\u003e\u003cp\u003eFor replacement work, compare the mount angle on the existing part before changing configurations. A 0 degree mount and a 3 degree mount can change the way the seat feels at the helm, especially on consoles where sightline, throttle reach, and steering position are already set.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis slider is a good match for boats where the helm or cockpit seat needs practical adjustment rather than fixed positioning. It suits operators who move between seated driving, standing at the console, docking, and fishing tasks where seat position changes through the day.\u003c\/p\u003e\u003cp\u003eAfter installation, periodically check the mounting hardware and slide action as part of normal seat maintenance, especially on boats exposed to vibration, washdowns, and saltwater air.\u003c\/p\u003e","brand":"Attwood Marine","offers":[{"title":"0 Degree","offer_id":52581897568437,"sku":"QBP748840-V1","price":208.92,"currency_code":"USD","in_stock":true},{"title":"3 Degree","offer_id":52581897601205,"sku":"QBP748840-V2","price":208.92,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1332815_qbp748840.webp?v=1780201394","url":"https:\/\/www.qualityboatparts.com\/products\/qbp748840","provider":"Quality Boat Parts","version":"1.0","type":"link"}
