These ACHLA SFB-02C brackets let you add a flower box to any flat surface up to 1.25 inches thick without drilling or permanent hardware. Made from heavy-duty wrought iron with a durable black powder coat, they support window boxes securely and resist rust in outdoor use. Sold as a pair, no assembly required.
Best for

- Outdoor spaces needing a classic black iron look that matches traditional or farmhouse decor
- Supporting medium-weight window boxes filled with annuals or small perennials
Not ideal for
- Surfaces thicker than 1.25 in - the clamp will not fit
- Heavy or oversized planter boxes - these brackets are rated for standard window boxes only
- Interior use where a decorative bracket is preferred over a utilitarian clamp-on design
