ALBO 16" Heavy Duty Flat Countertop Support Brackets 4 PCS, 300 lb 1/4" Steel - Hidden Flush-Mount Corbel | Matte Black Powder-Coated with Screws for Quartz Granite Wood Kitchen Island Bar Tops — Open-Box, 36% Off

SOLID 1/4" STEEL - Quarter-inch plate supports up to 300 lb per pair, replacing bulky corbels and locking down quartz, granite and wood counters on islands, bars and craft benches.

FLUSH-MOUNT PROFILE - Flat bar hides under the top, keeps knee space clear and leaves the crisp edge designers want for modern kitchens, coffee shops and breakfast bars.

READY 4-PACK - Four brackets span a 64" stud run at 16" centers; add extras for longer islands, saving money and shipping versus contractor bulk boxes made for heavy wall shelving.

COMPLETE HARDWARE - screws arrive sorted by size, letting you fasten to studs or masonry without last-minute store runs.

RUST-SAFE COATING - Durable matte-black powder finish blocks moisture, grease, UV and scratches, keeping brackets sharp in humid kitchens, seaside patios, brewpub bars and busy utility rooms.

MATERIAL-FRIENDLY EDGE - Chamfered sides protect laminate, quartz, granite, butcher block and tile backs from chips or hairline cracks during install, daily prep and cleanup routines.

CNC LASER CUT - Precision flatness and countersunk holes pull brackets tight to plywood sub-tops; no shim stacks or wobble, just a flush base ready for stone adhesive or wood glue-ups.

LOW-KEY STRENGTH - Only 2.5" tall yet five times stiffer than common 4 mm flush brackets, providing pro-grade rigidity that tames droop on 14" breakfast ledges, benches and laundry stations.

PROTECTIVE WRAP - Each plate ships in soft fabric-like film that prevents paint rub, scuffs and dust, so parts arrive workshop-clean and go straight from box to wall without touch-up sanding.

MULTI-ROOM USE - Ideal for kitchen islands, laundry counters, retail kiosks, tiny-home desks, RV galley refits and maker-shop worktops, turning blank walls into strong, invisible support zones.
