CADUKE Railing Planter Boxes 2 Pack are compact black window boxes designed to hang on railings and windowsills, creating instant balcony gardens without taking floor space.

These 16.9 x 6.9 x 5.5 inch planter boxes come as a two-pack with adjustable metal brackets so you can mount them on a wide range of railings. Built for both indoor and outdoor use, each box includes drainage features and a removable tray to manage excess water. The slim profile makes them ideal for apartments, patios, porches, and any narrow ledge where you want more plantings without sacrificing usable space.

How do these planter boxes attach to my railing?

The CADUKE boxes use adjustable metal brackets that secure the planter to railings between 1.6 and 4.9 inches wide. Brackets fasten firmly and can be repositioned to fit different rail shapes without specialized tools. A clear illustrated manual and included hardware simplify setup for most users.

• Two installation methods for horizontal or vertical mounting
• Installation typically requires no additional tools
• Illustrated instruction guide and necessary accessories included

Will these boxes drain properly for healthy plants?

Yes — each CADUKE planter is designed with bottom ventilation holes and a removable tray that captures excess water. The ventilation helps airflow to roots while the tray prevents runoff onto decks or balconies. Together they minimize waterlogging risk and make maintenance easier for casual and experienced gardeners alike.

• Bottom drainage holes for better root aeration
• Removable water-collection tray reduces mess

How much planting space does each box offer?

Each planter measures 16.9 x 6.9 x 5.5 inches, giving generous volume for multiple flowers, herbs, or small vegetables. The two-pack effectively doubles planting area, so you can arrange complementary crops or create coordinated displays. Their slender form factor is optimized to maximize soil volume while keeping the profile neat on railings or windowsills.

• Dimensions: 16.9 x 6.9 x 5.5 inches per box
• Ample capacity for mixed plantings—flowers, herbs, small veg

Are these planters durable for outdoor use?

CADUKE planter boxes pair sturdy construction with stable metal supports to withstand typical outdoor conditions. Weather-resistant materials and a secure bracket system reduce wobble and movement in breezy conditions. Routine care—emptying trays and protecting from extreme cold—will extend their life in year-round climates.

• Durable materials and metal supports for stability
