com-four Flower Box Balcony Holder – Adjustable, Set of 4

These metal flower box holders offer a straightforward way to bring colour to your balcony without picking up a drill. Each bracket clamps securely onto railings or parapet walls up to around 16 cm wide, using a simple wing screw system that you tighten by hand. The double-adjustment design means you can fine-tune the fit both to your railing and to the depth of your planter, making them compatible with a wide range of standard balcony boxes.

The coated metal construction is built to handle the elements through spring and summer, and the dark brown finish gives a neat, unobtrusive look that suits most balcony styles. When the season is over, they come away just as easily as they went on, so storage is no trouble at all. The pack includes four holders, which is typically enough for one or two generously planted window boxes.

These brackets suit anyone renting or simply reluctant to make permanent alterations to their balcony. Assembly is genuinely quick — no tools beyond a hand tighten — and the adjustability means they'll work across a good variety of railings and planters rather than being tied to one specific setup.
