ROCKRIVET MECHANICAL PLUG
The MTi Group ROCKRIVET is a retention plug for use in both underground and open pit mines. It works through using friction and interference of the plastic fins in the ROCKRIVET to hold onto the wall of the hole. The fins are designed to close like a collet which allows for optimum holding capacity and minimal leakage. The design also allows for a downline or firing line to pass through, preventing the likelihood of cut-offs or misfires.
