45 Degree Unistrut Brackets: A Complete Installation Guide

An Introduction to 45 Degree Unistrut Brackets

Unistrut, also known as strut channel, is a versatile metal framing system commonly used in structural support applications. Unistrut gets its name from having a uniform pattern of holes along the length of the channel. This allows Unistrut parts like brackets, fixtures, and fittings to connect to the channel at any point, offering flexibility for installation. One of the most popular Unistrut parts is the 45 degree bracket.

What are 45 Degree Unistrut Brackets?

A 45 degree Unistrut bracket is a load bearing metal bracket that connects at a 45 degree angle to Unistrut channel. These 90 degree angle brackets are among the most widely used Unistrut fittings. The design of the 45 degree Unistrut bracket makes it easy to build pipe supports and cable trays that turn corners at 45 degree angles.

Common Applications of 45 Degree Unistrut Brackets

There are many structural and mechanical applications for 45 degree Unistrut brackets:

• Constructing wire mesh cable trays for running electrical or data cabling overhead
• Pipe supports and pipe racks with 45 degree angles
• Structural bracing for solar panel installations
• Machine guarding and safety barricades
• Retrofitting structures with additional structural bracing

These are just a few examples. A 45 degree angle bracket can assist with any application that requires a strong 45 degree structural connection point.

Benefits of Using 45 Degree Unistrut Brackets

There are several notable benefits that make 45 degree Unistrut brackets a top choice for installers:

• Adjustability - The channel nuts used with Unistrut parts like 45 degree brackets allow the fitting to slide within the Unistrut channel. This makes it easy to adjust the positioning if required after the initial installation.
• Load Strength - With weight capacity ratings over 1,000 lbs per fitting, a 45 degree Unistrut bracket provides tremendous load bearing strength for structural installations.
• Corrosion Resistance - Top manufacturers powder coat 45 degree Unistrut brackets to resist rust and corrosion.
• Saves Time - 45 degree brackets eliminate the need to cut channel or tubing onsite to custom angles.
• Safety - Installing a 45 degree bracket secures pipes or cables firmly, reducing safety hazards.

Types of 45 Degree Unistrut Brackets

While a 45 degree Unistrut bracket serves one main purpose, connecting at a 45 degree angle, there are slight variations in design and weight capacity to suit different applications:

Light Duty 45 Degree Unistrut Brackets

A light duty 45 degree Unistrut bracket has a lower weight rating around 250-500 lbs but costs less. Light duty brackets work for cable trays, conduit, and other applications that don't require heavy load capacity.

Medium Duty 45 Degree Unistrut Brackets

For structural applications requiring good strength, a medium duty 45 degree Unistrut bracket is a practical choice. They can handle 700-1,000 lbs loads. Useful for solar farms, machine braces, and equipment platforms.

Heavy Duty 45 Degree Unistrut Brackets

At load capacities over 2,500 lbs per bracket, the heavy duty 45 degree Unistrut brackets handle major loads. These brackets work for large pipe racks, industrial platforms, catwalks, and heavy cable trays.

Specialty 45 Degree Unistrut Brackets

There are a few specialty designs like double 45 degree Unistrut brackets for connecting multiple channels and custom heavy gauge 45 degree brackets rated for extreme loads.

Key Specs and Features of 45 Degree Unistrut Brackets

Whether choosing light, medium, or heavy duty, 45 degree Unistrut brackets have some standard specifications to look for during product selection:

• Material Type - Most feature a steel construction with either a galvanized zinc coating or a polyester powder coat.
• Hole Pattern - The Unistrut hole pattern matches channels for easy slide on attachment with channel nuts/bolts.
• Height/Width - Dimensions for the height and width vary based on load rating and channel size.
• Angle - The brackets connect to Unistrut channel at precisely 45 degree angles.
• Weight Rating - The maximum weight each bracket can safely support during use.
• Quantity - Many options to purchase 45 degree brackets individually or in money saving multi-packs.

How to Install 45 Degree Unistrut Brackets

Once you determine the correct size and load capacity 45 degree Unistrut bracket needed, the installation process is straight forward. Here is an overview of how to properly mount 45 degree brackets:

Tools/Materials Needed

• 45 degree Unistrut brackets
• Unistrut channel to connect the brackets to
• Channel nuts and channel bolts
• Basic hand tools like wrench, drill, hammer, tape measure

Installation Steps

1. Measure and mark precise locations to install the Unistrut channel along the mounting surface.
2. Use appropriate fasteners to securely anchor the channel to the underlying structure.
3. Slide the channel nuts inside the channel per the markings.
4. Align the 45 degree bracket to the channel nuts and attach using channel bolts.
5. Repeat along the length of the installation, keeping spacing consistent between brackets for maximum support.
6. Double check alignment, tighten all connections, and test load rating after completing install.

With good planning, proper mounting hardware, and by confirming load ratings - a 45 degree Unistrut bracket installation should operate safely for many years before service is required. Be sure to inspect periodically for any signs of damage or loosening connections over time.

Conclusion

A durable and adaptable solution for a wide array of installations, the 45 degree Unistrut bracket delivers on strength, simplicity and cost savings. These versatile gold and black brackets secure reliably into Unistrut channel framing at a 45 degree angle. Trusted in commercial and industrial workplaces to bear weight up to several thousand pounds, 45 degree Unistrut brackets finish the job.

FAQs

What metals are used to construct 45 degree unistrut brackets?

Most 45 degree unistrut brackets feature an all-steel construction consisting of carbon steel, stainless steel, or galvanized steel. Aluminum is also sometimes used but steel offers higher strength.

What is the weight rating for heavy duty 45 degree brackets?

Heavy duty 45 degree unistrut brackets have very high weight capacities able to handle over 2,500 lbs per bracket. Some extreme duty custom brackets support loads upwards of 20,000 lbs!

Can I install 45 degree brackets horizontally or vertically?

The unique 45 degree angle design allows the brackets to connect either horizontally or vertically to Unistrut channel. This versatility supports all kinds of installations.

What length channel bolts are used with 45 degree Unistrut brackets?

For a secure connection, choose the channel bolt length so that the bolt inserts fully through the entire depth of the Unistrut channel - typically 1 to 3 inches depending on channel size.
