CADUKE Red Railing Planter Boxes 6-Pack — Adjustable Metal Brackets, Drainage & Removable Tray

If you want an easy, tidy way to add color or utility to a narrow ledge, the CADUKE 6 PCS railing planter set gives you six identical window boxes that click into place with adjustable supports. Each box is weather-ready, includes drainage and a removable tray, and fits a wide range of railing widths so you can plant multiple herbs, annuals, or compact vegetables without bulky pots.

How do these planter boxes attach to different railings?

The CADUKE brackets offer two installation modes so you can choose the most stable fit for your railing or windowsill. Brackets are metal and slide to accommodate railings from about 1.6 to 4.9 inches (4–12.5 cm) wide, then lock in place for a secure hold.

• Two mounting options: over-the-rail or under-rail clamp configuration.
• Adjustable bracket span fits common balcony and deck rails.
• Metal supports increase stability for outdoor use.

What features help my plants stay healthy outdoors?

Each box has bottom ventilation holes that let water drain and air circulate around roots, reducing the risk of waterlogging. A removable drip tray collects excess runoff while preserving some soil moisture for consistent growing conditions.

• Drainage holes prevent standing water and promote aeration.
• Removable tray captures overflow and simplifies watering control.
• Weather-resistant construction suited to year‑round outdoor exposure.

How much planting space does each box provide and what fits inside?

Each planter measures approximately 16.9 x 6.9 x 5.5 inches (43 x 17.5 x 14 cm), providing enough room for several small plants or a compact herb garden. The length and depth are optimized for shallow-root annuals, herb bunches, succulents, or multi-seedling arrangements.

• Large internal capacity for multiple small plants or mixed varieties.
• Shallow depth suitable for herbs, lettuce, annual flowers, and succulents.
• Uniform size across six boxes creates a cohesive display.

Is installing these planters difficult and what comes in the box?

CADUKE includes an illustrated manual and the required hardware so you can install most boxes without extra tools. The brackets and fasteners are provided, and customer support is available if you need assistance during assembly.

• Detailed step-by-step illustrated installation guide included.
• All mounting hardware supplied; typically no additional tools required.
• Manufacturer support offered for fit or installation questions.

Who is this for: these planter boxes suit balcony dwellers, apartment gardeners, and anyone looking to maximize limited outdoor or windowsill space with a tidy, repeatable planting system. If you want a coordinated set of durable, easy-to-mount containers for flowers, culinary herbs, or small vegetables, the CADUKE six-pack offers a convenient, weather-ready solution with built-in drainage and adaptable mounting hardware.
