Our Story

In 1976, contractor and inventor Steve Ventling saw a better way to brace roof trusses. Traditional wood bracing was time-consuming, inconsistent, and often a safety risk.

He set out to create a reusable, lightweight, and durable system that would make truss installation faster and safer without sacrificing strength.

Along with his business partner Cynthia Hert, Steve founded TrussLox LLC and developed the TrussLox Temporary Spreader Bar, earning a United States Patent for their innovation. The name says exactly what it does: TrussLox (pronounced “Truss Locks”) helps lock trusses into position for consistent spacing during installation.

Our mission remains the same today: build smarter, safer, and stronger with TrussLox.

Best product I have ever used.

This is not only a time saver but it literally took us 45 seconds to set 1 truss and release the cable and head to get another one….. cant really put a price on that kind production.

I AM A TRUSSLOX FAN!

I have been around the building industry since the eighties, and I have never seen a product as simple and effective as Trusslox. I was skeptical, but ordered the product for the first time in 2024. I raised a truss package by myself with my Kubota tractor and a ramp. With the truss in position I could raise each truss into position with a pulley and rope. With a 3” screw and my Dewalt cordless drill, one screw locks it into place. With a dozen bars, I raised 6 trusses, then braced underneath with a 12’ 2×4. Even the way the dozen bars lock together with a Velcro strap makes it easy to handle and store. Thank you for designing a great product.

Nothing but the best!

This is my jobsite. I had to buy another dozen packs just to do this monster! Worth every penny though!
