OUR GOAL: High Performance Motion

We offer pre-engineered modular component systems that inherently solve your motion requirements.

What is it? istrut® is a modular aluminum framing system. The modular extrusion components clamp and bolt together with tube clamps, barrel nuts, and plates. Its pre-engineered, patented design allows you to solve movement issues to get the job done. Traditional T-slot systems can't compare to the motion performance and aesthetics of istrut.
Support: Our customer service and technical support personnel and technicians are specialists in all aspects of istrut. We will listen to your requirements and help you solve your problems.
Kundel's mission is to provide quality products that help your team work safe and be more productive.


Simple Beam Design - Thick flanges offer motion and clamping capabilities at outstanding weight-to-strength ratio.

You Dream It, You Build It - and you don’t even need to weld it

Important Terminology
Profiles istrut comes in two extrusion profiles, "C” and Tube Beam shape.
Profile Style The shape or design of a modified profile with or without the barrel nut option.
Height The distance between tubes.
Series There are currently two series, 50 and 100. The difference between the series is the diameter of the tube.

The istrut CONCEPT

istrut’s creative design gives users the ability to build powerful applications. As you are designing your structure, we invite you to keep in mind the following built-in concepts:

Simple The outer flange of istrut provides a powerful and easy connection for clamps and plates.
Smart The outer tube forms a seamless runway that can be used with our trolleys to move tools, heavy objects, and more.
Tough istrut’s 45° tubular design redefines contemporary load distribution, allowing you to lift more with less.
Adaptable Uniquely designed tubing allows profiles, joints, and plates to connect in a multitude of ways.

Pull It All-Together With Motion Clamping System and Trolley Systems

istrut Clamping Systems literally brings everything together.
Available Clamps: Tube Clamps, Single, Double, Rail Clamp and Inside Clamp.
Many of the clamping systems utilize specially engineered barrel nuts.

istrut Trolley Systems give motion to your framing system.
Available Systems: Enclosed Trolleys, Beam Trolleys, and C Trolleys.
