Bolt in Competition Roll CageĀ
Our Competition Bolt-In Roll Cages are built to comply with MSUK standards and follow MSUK Appendix K design principles. Each cage is manufactured to sit snugly within the vehicle interior, improving chassis rigidity while maintaining cabin space and functionality.
The door bars are designed to allow easy access while still offering full lateral occupant protection. By positioning the bends lower and slightly forward of the seat, the driver and passenger can enter and exit the vehicle efficiently in emergencies, without compromising safety.
These cages are suitable for most UK-regulated motorsport events.
Buyer responsibility: Regulations may vary between championships and classes – it is the customerās responsibility to ensure the chosen specification meets the requirements of their specific event.
ā Design & Appearance – Bolt-In with a Weld-In Look
JP Cages design their bolt-in systems to offer the aesthetic and structural quality of a weld-in cage:
-
Door bars are welded directly to the front (A-pillar) legs, creating a seamless appearance from the side
-
No traditional X-joint style door bars – we use continuous one-piece door bar sections to avoid placing welds or joints in direct impact zones
-
Snug, tight-fitting tube work that follows the bodyline of the car
