Made from marine-grade PVC, this cap fits snugly over the top of a wood piling, shielding the exposed grain from rain, UV, and moisture — the main culprits behind piling top rot and splintering. The cone-head profile channels water off cleanly and gives your dock a consistent, finished appearance from the waterline up.\u003c\/p\u003e\n\n\u003ch3\u003ePart Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 91871F (store SKU: 686-91871F)\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 8 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Cone head (tapered top for water shedding)\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 an 8\" 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 — not at the waterline, as pilings often taper.

The most important thing to get right is the size — always measure at the top of the piling, not at the base. A cap that's too large will rock and collect water rather than shed it, which defeats the purpose entirely. If you're unsure of your piling size, we recommend bringing a measurement or a photo of the piling top when you order.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51037525442596,"sku":"686-91871F","price":20.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/686-91871F_51926c29-9040-49c3-9321-32ac6971a754.jpg?v=1783568247","url":"https:\/\/marisolmarine.com\/products\/dock-edge-cone-head-piling-cap-8-pvc-91871f","provider":"Marisol Marine Company","version":"1.0","type":"link"}
