Therwen Raised Garden Bed Corner Brackets 8-Pack with 128 Screws — Fits 2" x 12" Lumber, Rust-Resistant Black

These black, rust-resistant corner brackets let you build or reinforce raised beds, planter boxes and simple outdoor furniture with right-angle strength. Each bracket is sized for planks up to 2" x 12" and includes pre-drilled mounting holes so you can quickly fasten boards with the supplied screws. The set stacks for storage and uses a powder-like corrosion coating to help resist weathering in outdoor environments.

How do these brackets make building a raised bed easier?

The brackets create precise 90° corners and remove the need for complicated joinery, so assembly is faster and more consistent. Because the hardware secures boards externally, you can use standard lumber sizes and adjust bed height easily.

• Includes eight L-shaped metal brackets sized ~12" x 4.5" x 4.5" for clean corner joins.
• Comes with 128 screws sized to work with typical 2" x 12" planks for solid fastening.
• Pre-drilled holes let you use a screwdriver or drill to attach boards quickly.

Are the brackets durable enough for outdoor use?

These brackets are made from heavy-duty metal with a rust-resistant finish intended for outdoor exposure. Their construction offers good load resistance for soil and plantings when installed correctly, and the coated surface reduces visible corrosion over time.

• Metal construction provides strength and resists deformation under typical garden loads.
• Black corrosion coating helps protect against moisture and outdoor conditions.
• Stackable design for compact off-season storage without damage.

What lumber sizes and planter dimensions work with this set?

The brackets are designed to accept boards up to 2 inches thick and 12 inches wide, a common size for raised beds. You can build single or multi-tier beds by stacking boards and using additional brackets for each corner joint.

• Fits boards up to 2" thick and 12" wide—compatible with standard 2x12 lumber.
• Use eight brackets per rectangular bed (four corners); add more sets for taller or larger boxes.
• Screws included in the 128-piece count accommodate multiple fastening points per bracket.

Can these brackets be used for projects other than garden beds?

Yes—their right-angle support and corrosion-resistant finish make them useful for outdoor furniture, raised platforms, storage boxes and other DIY projects where rigid corner joints are needed. They work with various wood or composite board materials as long as thickness is within the specified range.

• Useful for planter boxes, bench frames, potting tables and small outdoor furniture.
• Compatible with wood, treated lumber, cedar, pine, or composite boards up to 2" x 12".
• External fastening preserves interior planting space versus internal corner posts.
