The Ultimate Clevis Hanger Size Chart (Updated for 2026)
A reliable clevis hanger size chart is essential for any professional involved in safe and efficient pipe installation. This guide provides the definitive resource for understanding pipe support systems, offering updated 2026 data to explain everything from reading dimensions to calculating load capacity. With this information, you can confidently select the perfect clevis hanger to ensure your project’s structural integrity and long-term performance.
Understanding the Basics: What is a Clevis Hanger?
A clevis hanger is a foundational component in pipe support systems, designed to suspend non-insulated, stationary horizontal pipelines from above. It provides a secure, pivoting connection point that accommodates pipe movement and ensures stability. It is a go-to choice for plumbing, HVAC, and fire protection systems due to its simplicity and reliability.
The Core Components of a Clevis Hanger
Understanding the anatomy of a clevis hanger is the first step in selecting the correct one from a clevis hanger size chart. Its design is straightforward but effective:
- The Clevis: A U-shaped metal piece with holes at the top to connect to a threaded hanger rod.
- The Lower Strap/Saddle: The bottom piece that cradles the pipe, providing support.
- The Clevis Pin: A pin or bolt that connects the clevis and the lower strap, creating a pivot point. The pin’s sizing is crucial for bearing the load.
In some installations, the clevis hanger is used alongside a channel bracket to distribute load and ensure a secure connection to overhead structural elements.
Common Clevis Hanger Materials and Finishes
The material and finish determine a hanger’s durability and suitability for different environments. Choosing the right one prevents corrosion and ensures a long service life.
Material/Finish | Common Use Case | Key Benefit |
Carbon Steel (Plain) | Dry, indoor environments with no corrosion risk. | Most cost-effective option. |
Electro-Galvanized Steel | Indoor applications where minor moisture may be present. | Provides a thin layer of zinc for basic corrosion resistance. |
Hot-Dip Galvanized Steel | Outdoor and corrosive environments (e.g., industrial plants, coastal areas). | Offers superior, thick-layer corrosion protection. |
Stainless Steel | Highly corrosive or sanitary environments (e.g., chemical plants, food processing). | Excellent resistance to rust and chemical corrosion. |
How to Read and Use a Clevis Hanger Size Chart
A clevis hanger size chart can seem intimidating, but it’s a simple tool once you understand its layout. This section breaks down the process of how to read a clevis hanger chart effectively.
Decoding Key Columns: Nominal Pipe Size, Max Load, and Dimensions
To master the clevis hanger size chart, follow these steps:- Find the Nominal Pipe Size (NPS): Locate the row corresponding to the pipe size you are supporting (e.g., 2″, 4″, 6″).
- Check the Maximum Recommended Load: This is the most critical column. It specifies the clevis hanger load capacity in pounds or kilograms. Always ensure your calculated load is below this value.
- Identify the Hanger Rod Size: This column tells you the required diameter of the threaded rod needed to suspend the hanger (e.g., 3/8″, 1/2″).
- Review Key Dimensions: Look for other measurements like ‘Center of Pipe to Top of Hanger’. These clevis hanger dimensions are vital for planning installation height and ensuring clearance.
Understanding Pipe OD vs. Nominal Pipe Size (NPS)
A common point of confusion for newcomers is the difference between NPS and the actual Outer Diameter (OD) of a pipe. They are not the same. For example, a 2-inch NPS pipe has an actual OD of 2.375 inches. Clevis hangers are sized by NPS to simplify the selection process, matching the hanger to the standard pipe name rather than a precise measurement. This standardization is key to comparing various pipe hanger sizes.
The Comprehensive Clevis Hanger Size Chart (Standard Dimensions)
Below is a typical standard clevis hanger chart. While this serves as an excellent reference, always consult the specific manufacturer’s data sheet before making a final purchase. The values in any clevis hanger size chart can vary slightly between brands.

Chart for Standard Steel Pipe (Schedule 40)
This sample standard clevis hanger chart covers common pipe hanger sizes.| Nominal Pipe Size (NPS) | Max Recommended Load (lbs) | Hanger Rod Size (in) | Center of Pipe to Top of Hanger (in) |
| 1/2″ | 610 | 3/8 | 1-7/8 |
| 1″ | 610 | 3/8 | 2-1/4 |
| 2″ | 730 | 1/2 | 3-1/8 |
| 3″ | 1130 | 5/8 | 4-1/4 |
| 4″ | 1550 | 3/4 | 5-1/4 |
| 6″ | 2300 | 7/8 | 7-1/4 |
| 8″ | 3260 | 1 | 9-1/2 |
| 10″ | 3800 | 1-1/8 | 11-1/2 |
| 12″ | 4500 | 1-1/4 | 13-1/2 |
Considerations for Insulated Pipe Support
When using a clevis hanger for pipe support with insulation, you must account for the increased overall diameter. The insulation adds bulk, requiring an oversized clevis hanger or the use of a pipe shield (or saddle) to protect the insulation from being crushed. Importantly, the weight of the insulation and any protective shield must be added to your total load calculation to ensure you do not exceed the hanger’s capacity.
These configurations are often part of a broader modular support system, which allows for customizable arrangements to suit complex mechanical layouts.
Critical Factors for Selecting the Right Clevis Hanger
Choosing the correct hanger goes beyond just matching the pipe size. You must consider the total load and the specific installation requirements.
Calculating and Verifying Clevis Hanger Load Capacity
Before consulting the clevis hanger size chart, calculate the total load your hanger must support. Use this simple formula: Total Load = (Weight of Pipe per foot x Span between Hangers) + Weight of Contents per foot + Weight of Insulation per foot After calculating the total load, apply a safety factor (consult project specifications, but 2.5 is common) and check that the final number is well below the clevis hanger load capacity listed on the chart.Why an Adjustable Clevis Hanger Might Be Necessary
In some situations, a standard hanger isn’t enough. An adjustable clevis hanger provides the ability to modify the elevation of the pipe after it has been installed. This is particularly useful for:
- Sloped Piping: Essential for gravity-flow systems like plumbing and drainage, where a precise slope must be maintained.
- Precise Alignment: Allows for fine-tuning the height of pipes to align with other equipment or connection points in complex mechanical systems.
The key benefit of an adjustable clevis hanger is its flexibility, which can save significant time and labor during installation and maintenance. When combined with a reliable pipe clamp support, it forms a complete, adjustable system that enhances installation efficiency.
Common Applications and Industry Standards
Using a high-quality clevis hanger for pipe support ensures compliance and safety. Industry standards are in place to guarantee performance and reliability across all manufacturers.
Adherence to MSS SP-58 Standards for Pipe Hangers
The Manufacturers Standardization Society (MSS) sets the industry benchmark for pipe supports with its SP-58 standard. This specification covers the material, design, fabrication, and inspection of pipe support components. When selecting a clevis hanger, look for products that are compliant with MSS SP-58. This ensures you are using a product that has been designed and tested to meet rigorous quality and safety requirements, a crucial factor for any clevis hanger for pipe support.
These standards are also essential for integrated systems like a strut support system, ensuring consistency and compatibility across all structural supports.
Insights on Quality from a Global Exporter: Ashish Exports
Understanding the nuances of material quality is paramount, whether dealing with fine chemicals or robust industrial hardware. A standard clevis hanger chart is only useful if the product it represents is manufactured to the highest standards.
From Aromatic Chemicals to Industrial Components: A Commitment to Quality
Since 1982, Ashish Exports has built a legacy of quality, first in mint products and now as a leading global exporter of essential oils and aromatic chemicals. Our decades of experience in exporting diverse industrial goods, including rear-assemblies (HSN: 87141090) and bicycle spares (HSN: 87149990), has provided deep insights into material science and quality control. The quality of a hot-dip galvanized clevis hanger, for example, depends entirely on the chemical processes used for its coating. This commitment to quality at a foundational, chemical level is what defines a reliable product, whether it’s an essential oil or an industrial component. This same principle applies to understanding the fine details of clevis hanger dimensions and pipe hanger sizes.Frequently Asked Questions
