How to Secure Railing Planters

If you have a railing or any part of your garden elevated from the ground, you may want to consider securing it with these tips. If there are any children in the area, they may be tempted to climb on the railings and fall off.

The railing could also become loose over time because of things like soil shifting, which can lead to an accident. You’ll need something heavy-duty enough not to break when people lean against it but lightweight enough that you don’t damage your plants by installing them incorrectly.

There’s no sense in spending all that time planting and then ruining everything by leaving your plants unprotected! So this post will give you helpful tips on how to secure railing planters while still getting all its benefits!

8 Steps to Follow on How to Secure Railing Planters

Step One: Look for a Decking Pattern

There are many different kinds of railing planters, but most look roughly the same. They have a flat top and a curved front section that forms the shape of a bowl. The back of the planter is usually a smooth vertical surface that extends up from this curve.

The railing planters usually come with an included fastening kit, which means you should be able to find the necessary hardware without any trouble.

Step Two: Choose a Fastening Point

To secure your railing planter to your deck rail, you need to find the part of the planter that will fit over your decking. Unfortunately, some manufacturers do not include any hardware with their planters; this often means there is only one way to attach the planter to your deck.

Other times, however, railing planters are equipped with fastening hardware that allows you to place the planter on either side of your railing if you need to find a way to secure both sides of your railing planter, start by reading your manufacturer’s instructions on how to attach the included hardware.

Step Three: Determine Hardware Placement

Placing the hardware on your railing planter is easy, especially if you purchased a kit that will fit over both sides of your deck railings. Once you find the part of your railing planter that fits over the top of your decking, look for two small holes at either end of the curve.

Placing the Hardware on Your Railing Planter Is Easy

These holes are where you will put the included screws and washers to attach the planter to your deck railing. These screws should be long enough to go through your railing and into the side of your planter. You may need to drill pilot holes in the planter, depending on how thick it is.

Step Four: Secure Hardware

In most cases, you will be able to secure your rail planters with screws and washers that come with your kit. In addition, look for a small piece of hardware that attaches securely to both sides of your railing planter.

When you attach this hardware, the planter should be secure enough that it will not detach easily. However, if you feel that the included hardware is not enough to secure your railing planter, you should also look into using other kinds of hardware, such as tee nuts and bolts.

Step Five: Secure the Top

Your railing planter should have a flat top that is perfect for mounting plants or other materials. You can secure this top by sliding a washer onto each of your screws and tightening them in place with pliers to hold everything in place.

Once you do this, your rail planters will be sturdy enough to handle any plants you put on them. However, it is a good idea to check for loose screws once or twice a year to ensure that everything is still in place.

Step Six: Make Adjustments

Some rail planters have fastening holes that are too short of slipping over the top of your railing, or they may not fit at all. This means you will have to take some time adjusting the length of your screws so they can be attached securely to your railing and planter.

Take Some and Time Adjusting the Length

Most rail planters have a “lip” on the edge that is attached to your deck railing. You can adjust this lip by removing some of the screws and sliding it either up or down, depending on where you want it to be. Doing so will allow you to attach more hardware if needed without worrying about the planter slipping off your deck railing.

Step Seven: Drill Holes for Tension Bolts

Some rail planters require tension bolts to be attached securely to your deck railings. These bolts are used when you cannot attach hardware directly onto the side of your deck railing so that they will require a different kind of fastening system.

If you use tension bolts, drill holes into your deck railing where the rail planter will attach. The size of these holes should be slightly smaller than the shaft of your tension bolt to ensure it stays in place securely. Once you have drilled these holes, insert the bolts and tighten them down with a wrench. In this article, you will read how to secure railing planters.

Step Eight: Secure the Bottom

Some rail planters have holes that allow you to secure them to your deck railing by inserting screws through these slots into the side of your deck railing. These are often used when you want to create a gap between two sets of railings, so they should be drilled in along the bottom portion of your deck’s boards.

Some Rail Planters Have Holes

These slots are usually on the bottom of deck rail planters and should be drilled into your deck railing on either side of aboard. Once you have drilled these holes, insert the screws and tighten them down with a wrench or screwdriver until the rail planter is secure.
