Countertop Support Brackets

• HEAVY-DUTY 5 MM STEEL — 0.20-in plate supports up to 400 lb per pair, replacing bulky corbels and locking down quartz, granite or wood counters for kitchens, bars, workshops and garages all year.
• PRINTED INSTALL GUIDE — foldout chart pairs spacing with overhang, includes drill bits & wall tips so DIYers mark once, avoid redrills and finish breakfast bars, vanities and shelves first try.
• ALL-IN-ONE HARDWARE KIT — screws and anchors in pouches give every fastener to secure into studs or stone, powering a full counter install without store runs.
• HIDDEN CORBEL DESIGN — 1.5-in vertical arm disappears under the slab, creating a clean floating line that upgrades kitchens, coffee bars, retail displays, lofts, tiny homes and RV cabinetry.
• RUST-RESISTANT COAT — durable matte-black powder finish blocks moisture, stains and scratches to keep brackets sharp in humid kitchens, outdoor patio bars, laundry rooms and busy utility spaces.
