Each kit includes four 22\" anchors sized to accept a 3.6\" x 3.6\" post, plus the screws and wrench needed for quick assembly. The black finish resists rust and weather, while the no-dig design speeds installation compared with pouring concrete.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these spikes install and how long does it take?\u003c\/h3\u003e\n\n\u003cp\u003eInstallation is straightforward: drive the spike into soil or hard-packed subsoil, then set the post into the internal sleeve and fasten it with the included screws. A single spike typically takes minutes to position and drive with a sledgehammer or post driver, faster than mixing and curing concrete.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eDrive-in length: 17\" lower section for deep anchoring.\u003c\/li\u003e\n  \u003cli\u003eTop sleeve: 5\" upper section for post insertion and adjustment.\u003c\/li\u003e\n  \u003cli\u003eHardware supplied: 16 hex screws with spring washers and 32 flat-head screws.\u003c\/li\u003e\n  \u003cli\u003eTool included: one wrench to tighten hex screws.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these anchors resist rust and outdoor wear?\u003c\/h3\u003e\n\n\u003cp\u003eYes. The anchors are constructed from carbon steel and finished with a black powder-coat that helps block corrosion and surface wear under normal outdoor conditions.
