At 87 inches tall with a 21-inch width and 24-inch depth, it fits most standard square outdoor propane pyramid heaters. The cover is constructed from 420D Oxford fabric with reinforced double-seam stitching and a silver-plated undercoating that creates a waterproof barrier on the interior lining. A zippered side opening allows the cover to be put on and taken off without lifting it over the full height of the heater. Adjustable drawstring straps at the hem secure the base against wind. A 90-day return policy applies; manufacturer warranty is 1 month.\u003c\/p\u003e\u003c\/section\u003e\u003csection class=\"product-why-choose\"\u003e\u003ch2\u003eWhy Customers Choose This Heater Cover\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e87-inch height accommodates most standard square propane pyramid patio heaters — confirm your heater’s height before ordering\u003c\/li\u003e\n\u003cli\u003e420D Oxford fabric is a heavy-duty outdoor cover material — significantly more durable than standard 210D or 300D polyester covers\u003c\/li\u003e\n\u003cli\u003eSilver-plated interior undercoating adds a waterproof barrier layer in addition to the outer fabric’s weather resistance\u003c\/li\u003e\n\u003cli\u003eReinforced double-seam stitching at stress points reduces the risk of seam failure under sustained wind and weight stress\u003c\/li\u003e\n\u003cli\u003eZippered side opening allows installation without lifting the full cover overhead — practical for tall pyramid heaters\u003c\/li\u003e\n\u003cli\u003eAdjustable drawstring hem straps prevent wind from lifting or displacing the cover at the base\u003c\/li\u003e\n\u003cli\u003eBlack finish is low-profile and suits most patio aesthetics without drawing attention\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/section\u003e\u003csection class=\"product-highlights\"\u003e\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cdiv class=\"highlight-item\"\u003e\n\u003ch3\u003e420D Oxford Fabric with Double-Seam Stitching\u003c\/h3\u003e\n\u003cp\u003e420D Oxford fabric is a woven polyester fabric commonly used in heavy-duty outdoor covers, bags, and protective equipment. The “D” rating (denier) measures fiber thickness — 420D indicates thick, abrasion-resistant fibers significantly heavier than the 210D or 300D fabrics used in standard lower-cost covers. The double-seam stitching reinforces the seams that experience the most stress during installation, removal, and wind loading — the points where covers most commonly fail. Together, 420D fabric and double-seam construction represent a cover built for sustained outdoor exposure rather than occasional seasonal use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"highlight-item\"\u003e\n\u003ch3\u003eSilver-Plated Waterproof Undercoating\u003c\/h3\u003e\n\u003cp\u003eThe interior lining of the cover features a silver-plated coating that functions as a waterproof barrier, preventing moisture from penetrating through the fabric and reaching the heater surface. The silver undercoating also provides a degree of heat and UV reflectance on the interior surface. This dual-layer protection — outer Oxford fabric shedding surface water and the inner silver coating blocking any penetrating moisture — provides more reliable waterproofing than a single-layer coated fabric cover.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"highlight-item\"\u003e\n\u003ch3\u003eZippered Side Opening\u003c\/h3\u003e\n\u003cp\u003eRather than requiring the user to lift a full-length cover overhead — impractical for an 87-inch tall heater — the cover includes a zippered side opening that allows it to be placed over and removed from the heater from the side. This makes cover installation and removal a straightforward single-person task. Keep the zipper clean and free of debris for smooth operation; do not force a stuck zipper as this can damage the zipper tape.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"highlight-item\"\u003e\n\u003ch3\u003eAdjustable Drawstring Hem\u003c\/h3\u003e\n\u003cp\u003eThe cover’s base hem includes adjustable drawstring straps that cinch around the base of the heater frame to prevent the cover from being lifted or displaced by wind.
