This plastic saddle-style planter is available in several different colors. There are drainage holes in the bottom to allow excess water to escape and it comes with fasteners to make it more sturdy when placed on your railing. It fits rails from one to four inches wide.

Some reviewers found the sides bowed out when filled with soil. It also appears to be most suited for railings around the four-inch mark. Reviewers praise the stabilizing fasteners, however, and like that the planter has plenty of room inside.

If your area isn't very wide or has features that prevent wider boxes from being compatible, then these tiered boxes are a good choice. You have the option of a single tier, two tiers, or three tiers (at different price points), but they all latch onto your railing with a metal bracket that hooks over the railing.

The boxes are the perfect size for herbs and will make for an interesting and stylish herb garden. You have the option of adding a drainage hole to the planters if required. Reviewers love these planters, saying they're unique and that they are as described.

Available in three different lengths, this planter is made from steel. It includes a natural coco liner, which acts both as a barrier to stop any soil from escaping and a drainage system for excess water. The planter is attached to your railing with adjustable metal brackets and all of the hardware you need is included.

A few reviewers report that the steel frame rusted or the brackets are flimsy. For most reviewers though, this planter was easy to install on their railings. The depth of the planter is praised and many reviewers have been able to plant herbs and colorful flowers in them.

Available in either black or brown, this is a set of three identical hanging baskets. Each basket has two hangers that hook over the railing and you can fill them with any pot that fits. The hooks fit over railings of two and a half inches and they have a stabilizing feature at the back.

The metal base of the baskets is pretty thin, so some reviewers found them to be too weak and small for their plant pots. Many reviewers love these baskets, however, saying they are easy to fit and have stood up to some windy days. They find the baskets to be cute and match perfectly with metal railings.

This planter's brackets can be adjusted to fit any railing that measures between one inch to just over four inches. The planter also has support bars to help it remain level and secure. A reservoir system allows the plants to self-water, so you don't need to water them yourself as often.

A few reviewers report that the plastic brackets couldn't hold the weight of a filled planter and broke. There are also remarks that the railing needs to be flat for these to fit correctly.

However, reviewers like how many plants they can hold and say that they look great on their railings. They praise the addition of the support bars for keeping the planter steady.

This set of 10 small, colorful hanging pots is enough to brighten up any railing. They can hook onto railings or horizontal bars, but the hooks are also removable so they can be placed on any flat surface, also. The pots have a drainage hole at the bottom.

Pay attention to the dimensions, as they're not large. There are also a few comments that some arrived with defects or bent.

However, many reviewers love these colorful pots and say that they look great on their railings and fences. They say they're cute and just the right size for a single small plant.

These planters have a curved exterior, giving them a more modern and contemporary look. The two identical planters are designed for use on narrower railings with a maximum width of two and three-quarter inches. They have stabilizers that can be used to secure them to your railing.

A few reviewers report that the planters can break easily and there are no drainage holes in the bottom. However, reviewers say that they look great and if fitted correctly are very sturdy and resilient. They also like that the planters are deep, allowing for a wider variety of plants.

This set has three planters that sit on your railing, and a modular planter that then fits on top of them. The planters can be used individually, but as a group the unique style and shape make these railing planters stand out. The planters are made of plastic with a terra cotta finish and two drainage holes in each planter.

Some reviewers found the top planter doesn't fit securely in place, and note that the planters are designed for thick railings only. If you have railings of the right size, however, these planters are recommended by many reviewers. They say the planters are sturdy and look great when filled with plants.
