CobraCo® 24-Inch Black Flower Box Holder With Adjustable Hanging Brackets


Patent-pending technology allows CobraCo® flower box and pot holders to adjust to fit nearly any size railing.
The CobraCo® 24-Inch Black Flower Box Holder With Adjustable Hanging Brackets is easy to attach to your deck or porch railing. The holder, which has an elegant black finish, can hold up to a 24-inch flower box, but it also can be used with a variety of smaller-sized flower boxes or use it to hold multiple smaller flower boxes. 

Attaching and securing the flower box holder
With the adjustable railing brackets, you can attach the flower box holder to nearly any railing around your home. The sizing variety is permitted thanks to the interchangeable clasps -- use the short end for smaller railings and the long end for wider railings.
  • Use the short end of the enclosed L-shaped clasp for 2 inch to 4 inch railings (wrought iron, aluminum or vertical wood). 
  • Use the long end for 5 inch to 6 inch railings (2 inch by 4 inch to 2 inch by 6 inch railings).
Once you know which clasp end you should use, just use a screwdriver to lightly tighten the screws and nuts and then set the flower box in place.

The Bumper
Your CobraCo® Adjustable Flower Box Holder has a special design feature that helps level out the holder. See the video below for details.




Quality Construction
This flower box holder was built with high-quality metal to ensure its strength and reliability from one year to the next. The holder's basic frame utilizes a thin horizontal top rim with four vertical bars that meet at the base for support while keeping your flower box visible. This flower box holder has a black finish that nicely camouflages it against darker colored boxes and other decor.
With so many ways to display your flowers and plants, you can add beauty to any deck or porch railing.

How to Decorate your Deck with Flower Boxes


flower  boxes

Flower boxes and biodegradable coco planters can add some wonderful color to a deck. If your deck has a suitable railing, that's the natural place to host a hanging flower box. If that won't work, try placing a flower box directly on top of the railing -- just be careful to secure it from falling!  More options include using freestanding flower boxes, coco baskets and plant stands.


If you are building a new deck, plan ahead so you can include the flower boxes you want on your deck. CobraCo's adjustable hanging basket and flower pot holders offer an opportunity to customize and redecorate your space throughout the year.


When planning your deck railing, think about how flower boxes can hang over the deck railing. If the deck is near the ground, you may want to use flower box stands. These raise a flower box up, and doing so brings the plants in line with the deck.


Decorating  Your Deck - flower boxes

Looking for a liner for your planter? Try using a biodegradable coco liner, an eco liner or plastic inserts. Flower box holders are another option.


Once you have your flower boxes positioned appropriately on your deck railing, all that’s left is to make your plant selections!
