When Should You Use Clevis Pipe Hangers?

A common problem many DIY'ers both new and experienced face is trying to set up heavy-use pipe systems in areas with small amounts of space. A not-so-common solution is to use overhead hangers to reinforce the pipe system. Clevis hangers are awesome, low-cost tools that strengthen and support various pipe systems and help prevent breaks. This week's blog post gives a basic rundown on and explains how to use clevis hangers. Without further ado, let's get started!

What Exactly Is a Clevis Pipe Hanger?

Clevis hangers are two clevises, usually one V-shaped and one U-shaped, attachedĀ  with a metal bolt. The slimmer, V-shaped clevis attaches to the ceiling via a drilled-in metal rod. The wider, U-shaped clevis holds the pipe securely in place. These hangers are great for heavy-use pipe systems that need extra support but do not have a lot of space available. Additionally, the low price of clevis hangers makes them suitable for projects both small and large.

When Do I Use Clevis Pipe Hangers?

Even though the only applications that require clevis hangers are support for sloping pipelines, they fit well into any DIY pipe project that requires extra support. If you choose to use Clevis hangers, the first step is to choose the appropriate hanger size. You will want to choose a hanger size that corresponds to the outside diameter of the pipe (PVC Fittings online carries clevis pipe hangers in sizes ranging from 1/2" to 4"). When deciding on the number of hangers to use, the general rule is one hanger every two feet for smaller pipelines and one hanger every foot for larger pipelines. However, there is no exact science behind using clevis pipe hangers. You can use more or less depending on the specific needs of the project at hand.

How Do I Install Clevis Pipe Hangers?

The next step is choosing metal rods for hanger installation. Find a rod that fits into the hole of the U-shaped clevis of your hanger. You will also want to know how far you plan to hang the pipe from the ceiling and choose rods with corresponding lengths. We recommend that you use two appropriately-sized nuts per rod to keep the hangers locked into place.

Once you have all the materials, the final step is to install the clevis pipe hangers into your pipe system. Use an electric drill with a bit slightly smaller than the diameter of your metal rod and make a small start in the ceiling. This is to ensure the metal rod fits firmly into place. Next, slide a nut onto the rod and remove the bolt from your clevis pipe hanger. Slide the V-shaped clevis onto the rod, follow it up with a second nut, and make sure that both nuts are firmly secured to the rod. Finally, move the pipe into place and re-attach the U-shaped clevis, and you're done! Simply repeat these steps for each individual hanger installation. While the hangers prevent horizontal movement of the pipe, most allow for some vertical adjustments without removing the pipe. To alter the vertical placement of your hanger, simply loosen the bolts around the V-shaped clevis. The ability to adjust the vertical placement of these hangers makes them ideal for projects on sloped surfaces.
