RGSFB
The MCT Brattberg RGSFB is a robust, bolted transit frame designed for applications where welding is prohibited or induces unacceptable stress. Optimized for marine, offshore, and industrial installations , this system provides fire, water, gas, and EMI sealing—with the added benefits of on-site pressure testing and bolt-down reliability.
