Y&M6 PCS Adjustable Planter Box Brackets for Window Boxes Planters, Heavy Duty Wall Mounted Hooks Hangers for Flower Baskets Holder Durable, Hanging Brackets for Fence Patio Garden Balcony

These are really awesome! You can configure them to fit any railing or even wall mount them, and they're very sturdy. Not cheap materials. The only reason I didn't give them five stars is because I think they're a bit pricey for something made in China.

These brackets are very sturdy, i had smaller railing but were easy to adapt.

Was having trouble finding appropriate brackets for our deck rail flower trays. Although these were more expensive than I would have liked, they are exactly what I needed. Very high quality, they are very versatile in how they can be used. The hardware is the best quality I’ve ever seen for this type of thing. It took a little while for me to figure out the exact configuration I needed but that’s part of the bracket’s flexibility.

The brackets were quite heavy and sturdy. In fact heavier than I expected. I did have a bit of difficulty trying to assemble them and figure out how to use them correctly. It did not come with a assembling instruction sheet.

While I did keep and use these brackets, they're not as perfect as I had hoped:1) You have to REALLY figure out the instructions.2) The biggest downside for me is the fact that the way the bottom arm is attached; the screw/nut that holds the pieces together now interferes with the back of the planter you want to put into the bracket! You will want to make sure that the height of your planter is lower that that screw.

Easily adaptable to many railings and worked very well for my application. No difficulty with assembly.

I struggled with these brackets to try and make them work with my thin white fence but it just woukd not work I am sure it’s fine with a thick fence. They are well made and sturdy but just not for my fence..

Easy to install and versatile with multiple window box styles
