HKZ 2-Pack 24-inch Railing Planter Boxes — Steel Balcony & Window Planters with Coco Liners and Adjustable Brackets

These are two 24-inch HKZ steel railing planter boxes with coco liners and adjustable brackets for hanging on decks, balconies, fences, or mounting to walls.

Give small outdoor spaces an instant upgrade with a matching pair of HKZ railing planters designed for balconies, windows, and fences. Built from powder-coated steel and supplied with coconut-fiber liners and an installation kit, this 2-pack balances durability and plant-friendly drainage while keeping installation straightforward. The design helps you display seasonal flowers, herbs, or trailing plants without taking up floor space.

How do these planters attach to my balcony or deck railing?

The HKZ planters include adjustable metal brackets that hook over railings 3" to 6" wide for a secure fit and quick setup. For fence slats or nonstandard rails, zip ties are provided; expansion screws are included for permanent wall mounting.

• Adjustable brackets fit most 3"–6" rails
• Zip ties for alternate fence attachment
• Expansion screws for mounting to masonry or wood walls
• Simple hand tools required for final tightening

What materials and care features keep plants healthy?

The box is made from heavy-duty steel with a black powder coating to resist rust and weathering, while the included coco coir liners retain moisture and allow airflow for healthier root systems. Together they offer a durable structure and a breathable planting medium suitable for ornamental flowers and shallow-rooted herbs.

• Powder-coated steel resists corrosion
• 100% natural coco coir balances water retention and drainage
• Liners slowly release stored nutrients to roots
• Suitable for seasonal outdoors use in most climates

How large are these window boxes and how much soil do they hold?

Each planter measures 24 inches across, providing a long, narrow trough ideal for compact arrangements or a row of plants. The shallow profile is perfect for annuals, small perennials, and culinary herbs but not for deep-rooted trees or large shrubs.

• Length: 24 inches for broad continuous displays
• Shallow depth suited to bedding plants and herbs
• Pair offers doubled planting area across a railing or window
• Use quality potting mix compatible with coco liners

What comes in the box and how easy is assembly?

The set arrives with two 24" steel planter boxes, two coco coir liners, adjustable brackets, zip ties and expansion screws, plus simple instructions for fast assembly. Most customers can assemble both units in under 30 minutes using basic tools.

• Two 24" powder-coated steel planter boxes
• Two 100% coconut-fiber liners included
• Mounting hardware: adjustable brackets, zip ties, expansion screws
