Made from marine-grade PVC, this cap slips over the top of a 12\" diameter wood piling to shield it from rain, sun, and moisture intrusion — the leading causes of piling top rot and splintering. The cone-head profile sheds water cleanly and gives your dock a neat, finished look that lasts season after season.\u003c\/p\u003e\n\n\u003ch3\u003ePart Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e DE91812F (store SKU: 686-DE91812F)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Dock Edge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Cone Head Piling Cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Marine-grade PVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiling Diameter:\u003c\/strong\u003e 12 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Cone head (flat cone profile, no fin)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRound wood dock pilings with a 12\" diameter at the top\u003c\/li\u003e\n\u003cli\u003eFixed and floating dock piling installations\u003c\/li\u003e\n\u003cli\u003eMarina berth pilings, private dock pilings, and mooring pile structures\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment note:\u003c\/strong\u003e Measure your piling diameter at the top before ordering.

See our other Dock Edge sizes if your piling is smaller or larger.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWill this work on a piling that is slightly tapered at the top?\u003c\/strong\u003e Yes — a small taper is normal for wood pilings. The cone-head design can accommodate minor variation. If the taper is severe, the cap may sit high or rock; dressing the top flat will give a better fit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs marine-grade PVC UV-resistant?\u003c\/strong\u003e Yes — Dock Edge's marine-grade PVC is formulated for outdoor exposure. Expect good performance for multiple seasons, but inspect annually for UV-related brittleness in very sunny climates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDo I need to use screws or fasteners?\u003c\/strong\u003e Not typically. The cap relies on friction fit. In exposed locations with strong wave action or wind, a bead of marine sealant around the inside rim can improve retention.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003ePiling caps are one of those items customers often overlook until the top of a piling starts to check and split. The DE91812F is our go-to recommendation for 12\" pilings — it's a simple, cost-effective way to extend the life of a piling significantly. The most common issue we see is customers ordering without measuring first. Wood pilings vary — a \"12-inch piling\" at the waterline may be 10\" or 11\" at the top after years of weathering. Always measure at the cap installation point before ordering. Also note: this is the cone-head (tapered top) version — Dock Edge also makes a flat-top cap in the same family, so confirm the profile you want before purchasing.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51037524033572,"sku":"686-DE91812F","price":23.79,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/686-91872F_80771448-8780-4f73-a1ff-ad8d2ce646c8.jpg?v=1783568213","url":"https:\/\/marisolmarine.com\/products\/dock-edge-cone-head-piling-cap-12-pvc-de91812f","provider":"Marisol Marine Company","version":"1.0","type":"link"}
