Hi Flame raised garden bed corner brackets 17" black set of 4 — 2 mm powder-coated steel, screws included

These Hi-Flame 17" corner brackets are a four-piece kit that fastens 2x20" or 2x24" lumber into sturdy, rust-resistant raised garden beds—screws included.

If you want a simple, durable way to build or repair a raised planter, these powder-coated steel corner brackets give you a clean, professional look without complicated joinery. Each bracket is 17 inches tall and designed to form neat 3" x 3" corners that hold common 2" x 10" to 2" x 12" boards (sold separately). The set includes 10 high-strength M5 black screws per bracket so you can assemble your bed right away.

How do these brackets make a raised bed more durable?

The brackets are made from 2 mm powder-coated steel, which resists rust and holds up to seasonal outdoor use. Their shaped corners distribute pressure evenly across the board ends, reducing splitting and loosening over time. With the supplied high-strength screws, connections stay tight without relying on glued joints or complicated carpentry.

• 2 mm powder-coated steel for corrosion resistance
• Formed 3" x 3" corner for even load distribution
• 10 x M5 high-strength black screws included per bracket

What board sizes and bed heights do these fit?

These brackets are sized for typical dimensional lumber used in garden beds: they accept two-piece boards such as 2" x 10" up to 2" x 12" (commonly labeled 2x10 or 2x12) and are compatible with bed heights from about 10" to 24". The 17" bracket height is tall enough to support deeper root zones while keeping a compact profile for easier access.

• Fits standard 2" x 10" and 2" x 12" boards (nominal dimensions)
• Supports raised bed heights roughly 10"–24"
• Ideal for four-board side construction per corner

How easy is assembly and what’s included?

Assembly is straightforward: hold two boards in the bracket, align, and drive in the supplied screws. Each bracket ships with ten pre-selected M5 black screws engineered to match the bracket holes and provide a secure hold. No welding, adhesives, or special tools are required—just a drill or impact driver.

• Set of 4 brackets — one per corner
• 40 x M5 high-strength black screws total (10 per bracket)
• Basic tools (drill/driver) required; boards not included

Will these brackets work in outdoor garden conditions?

The powder-coated finish helps resist moisture and surface corrosion, and the steel construction gives multi-season strength. While built for outdoor use, placing the brackets on properly treated or naturally rot-resistant lumber will maximize lifespan. Routine checks and re-tightening of screws after winter will keep the bed stable for years.

• Powder-coated finish for improved weather resistance
• Steel construction designed for repeated seasonal use
• Best with rot-resistant or treated lumber for longevity

Choose this Hi-Flame 17" bracket set if you plan to use standard 2" x 10"/2" x 12" boards, prefer a black powder-coated aesthetic, and value quick assembly with all necessary screws included.
