Strength
With our patent secured over a decade ago we began production on our cages. Each collar, cap, and tube component in our system is produced in house. This gives us total control over manufacturing to ensure that once a fabrication collar leaves our facility and gets installed in your project, we know it will continue to uphold our sterling reputation.
Our locking collars and caps are solid 1/2" thick CNC machined steel and produced in house. Each cap is secured to it matching collar with six 5/16" x 1" grade 8 socket head cap screws. Once a cap is secured to it collar it becomes a solid, unbreakable joint. This means assembly and disassembly is achieved without welding or cutting which could potentially damage your vehicle interior or expensive powdercoat/paint finish.
