ALBO 16" Heavy Duty Countertop Support Brackets 4PCS, 400 lb 5 mm Steel – Hidden Floating Shelf Corbel | Matte Black Powder-Coated L Brackets Incl Screws & Anchors for Quartz Granite Wood Concrete — Open-Box, 30% Off

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.

MULTI-SURFACE SAFE — beveled edges shield quartz, granite, wood, concrete or laminate tops up to 1½ in thick, preventing chips or marks and letting renovators mix countertop materials confidently.

SLEEK INDUSTRIAL STYLE — crisp welds, smooth corners and a slim profile blend with loft, Scandinavian and modern décor while fitting tight alcoves, minimalist open shelving and garage walls.

ZERO-SAG PRECISION — every bracket is CNC-squared to 90° ± 0.5°, preventing droop and keeping bar tops level after years of elbows, small appliances or toolboxes, no mid-project tweaks required.

PROTECTIVE WRAP SHIP — each bracket arrives individually swaddled in soft fabric-like film that blocks scuffs, paint rub and dust, so hardware comes out of the box pristine for same-day install.

VERSATILE APPLICATIONS — ideal for counters, benches, laundry stations, garage racks, RV or van builds, studio workbenches and craft rooms, turning blank walls into strong, space-saving surfaces.
