Get to Know Unistrut Accessories

June 3, 2025

Unistrut is well known for its signature continuous channel that can easily create custom support solutions, but what is that channel without the appropriate accessories? Unistrut's line of attachments and components is what takes simple strut and turns it into an adaptable, modular system.  

Unistrut Accessories Create an Engineered System 

Unistrut is the original metal framing system featuring a unique, weldless connection. This is made possible by the Unistrut line of fittings, fasteners, hangers, clamps, and more. It eliminates welding and drilling through the use of nut and bolt connections that can occur anywhere on the channel. This connection method gives Unistrut one of its biggest advantages over traditional welded steel structures: adjustability.  

The Unistrut system is 100% adjustable and reusable. Whether you need a slight adjustment to account for a change when assembling on site or a full redesign to accommodate new priorities, Unistrut frames are simply bolted together using various Unistrut attachments. No drilling or welding means that parts can be dismantled, repurposed, and adjusted as needs change.  

Unistrut Accessories Ensure Safety 

Unistrut systems are often used to support medical equipment, MEP systems, and access platforms. The best way to ensure the safety of both equipment and staff is to use Unistrut accessories alongside Unistrut channel. Each component is designed to work seamlessly with Unistrut channel to create connections that are as dependable as welding. 

Unistrut is tested as an engineered system backed by a catalog full of pertinent information, including load ratings and applications. Engineers and architects rely on this information when creating drawings and plans. By using the recommended parts as specified and accurately determining channel load limits, you can rest assured that your Unistrut support system will be secure. 

Unistrut Accessories and Uses 

Below are some of the more commonly used Unistrut components and examples of their application. The full line of Unistrut accessories is available in the Unistrut General Engineering catalog.  


Nuts and Hardware

Unistrut Accessories Spring NutsSpring Nuts

Spring nuts are used in any type of connection between Unistrut channels or channel to other components. The spring holds the nut in a precise location, which is especially useful for overhead applications.  

Unistrut Accessories Channel NutsChannel Nuts  

Channel nuts work in much the same way as spring nuts. Just like spring nuts, channel nuts create a strong, vise-like grip when tightened against the Unistrut channel edges, creating a box-like configuration for strength. 

Unistrut Accessories Hex Head BoltsHex Head Bolts

All Unistrut nuts require a bolt to complete the connection. Bolts require only a wrench to tighten the nuts to the channel, creating a connection that is as secure as welding using only hand tools.  


General Fittings 

Unistrut Accessories Flat Plate Fittings

Flat Plate Fittings

Flat plate fittings form a weldless connection at a flat, 180-degree angle, between intersecting or parallel channel or as a way to extend channel. Flat plate fittings are also integral to connecting Unistrut to threaded rod for drop-downs.  

Unistrut Accessories 90 Degree Fittings

90 Degree Fittings 

Commonly used to create right angle connections between vertical and horizontal channel, 90-degree fittings can also be used to connect channel to other surfaces, like a wall.  

Unistrut Accessories Angular Fittings

Angular Fittings 

When Unistrut needs to be attached at an angle other than 90 degrees, angular fittings can create those connections. These fittings allow users to create custom solutions even when non-standard angles are at play.  

Unistrut Accessories Z Shape Fittings

Z Shape Fittings

Z shape fittings can be used to connect either parallel channels that need to be offset or perpendicular channels that are stacked on top of one another, creating different elevations in a tight space.   

U Shape Fittings 

U shape fittings are commonly used when a channel needs to be securely enclosed or where a looped support structure is needed.  

Unistrut Accessories Wing Shape Fittings

Wing Shape Fittings 

Wing shape fittings allow multiple channels to connect at different angles from one fitting. These are commonly seen in shelving or racking systems.  

Unistrut Accessories Post Bases

Post Bases 

Post bases provide stability for vertical Unistrut channel and can be securely installed in many types of surfaces, including concrete.  

Unistrut Accessories Pipe Clamps

Pipe Clamps 

Pipe clamps, hangers, and brackets support electrical and mechanical services alongside Unistrut channel. They provide a secure hold that prevents movement for pipes, conduits, and tubing.  

Unistrut Accessories Brackets and Brace Fittings

Brackets and Brace Fittings 

Unistrut brackets and brace fittings are commonly used for shelving, adjustable racking, cable tray support, equipment support, stair treads, and more.  

Unistrut Accessories Beam Clamps

Beam Clamps 

Beam clamps attach Unistrut channel to existing structural elements like bar joists. Using these clamps provides a secure connection without the need for welding.  

Unistrut Accessories Trolleys

Trolleys 

Unistrut trolley systems can be designed to move equipment weighing anywhere from ten to 600 pounds with reliability and ease. They are commonly used in applications like curtain tracks or movable shelving units.  


Other Fixtures 

Unistrut Accessories Electrical Fittings

Electrical Fittings 

Electrical fittings turn metal framing components into electrical support structures that are UL-listed and CSA-approved. These fixtures can be used for raceways, trapeze hangers, cable-tray supports, lighting grids, and more.  

Unistrut Concrete Inserts

Concrete Inserts 

Concrete inserts are anchors that connect Unistrut channel to pre-cast, pre-stressed, or poured-in-place concrete floors, walls, or ceilings.
