It is part of TACO Marine's ball and socket top fitting hardware, giving the tube end a secure cap with movement at the joint instead of a fixed, rigid connection.\u003c\/p\u003e\u003cp\u003eThis set screw version is built from Type 316L stainless steel and includes a Delrin insert that helps reduce rattle while allowing smooth movement through the fitting. The 1-1\/8 inch tube entry depth gives the cap enough engagement on the tube for a solid installation when properly fitted and tightened.\u003c\/p\u003e\u003cp\u003eIt is a practical replacement or build component for bimini tops, canvas frames, shade structures, and other 7\/8 inch marine tubing assemblies where corrosion resistance, a polished finish, and quiet movement matter on board.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eFits 7\/8 inch outside diameter tube for common marine canvas and shade frame applications.\u003c\/li\u003e\n\u003cli\u003eType 316L stainless steel construction suits saltwater exposure better than general-purpose hardware.\u003c\/li\u003e\n\u003cli\u003ePolished finish matches stainless tubing and gives the frame end a finished appearance.\u003c\/li\u003e\n\u003cli\u003eSet screw fastening makes installation straightforward without relying on a pop-rivet connection for this version.\u003c\/li\u003e\n\u003cli\u003eDelrin insert helps reduce rattling and keeps movement at the joint smoother during use.\u003c\/li\u003e\n\u003cli\u003eBall and socket pivot design allows rotation at the connection point rather than locking the tube end in one fixed position.\u003c\/li\u003e\n\u003cli\u003e1-1\/8 inch tube entry depth supports a stable fit when installed on the correct tube size.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eConfirm the tube is 7\/8 inch outside diameter before installation, since this cap is sized specifically for that tubing. The tube end should be clean, round, and free of burrs so the fitting can seat fully to its intended entry depth.\u003c\/p\u003e\u003cp\u003eThe set screw should be tightened firmly enough to hold the cap in place without crushing or distorting the tubing. On older canvas frames, inspect the tube end for wear, corrosion, or elongation before fitting the replacement hardware.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis top cap is a good match for boat owners, riggers, and canvas shops working on stainless bimini or shade frame assemblies that use 7\/8 inch tube. It is especially useful when a worn end fitting has started to rattle, bind, or look out of place against the rest of the frame.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eRinse the fitting with fresh water after saltwater use, especially around the set screw and pivot area. Periodic cleaning helps preserve the polished finish and reduces buildup that can affect movement over time.\u003c\/p\u003e","brand":"TACO Marine","offers":[{"title":"Default Title","offer_id":52023088939189,"sku":"QBP677479","price":39.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1331578_qbp677479.jpg?v=1780191699","url":"https:\/\/www.qualityboatparts.com\/products\/qbp677479","provider":"Quality Boat Parts","version":"1.0","type":"link"}
