1. High crank conversion clamps. Made from durable, high-quality material, these high crank conversion clamps are designed to convert a standard 8-mm bolt thread into a set of tall crank posts. 2. Heavy-duty battery posts. Ideal for use with larger inverters or multiple distribution points, these M8 posts accommodate heavy battery clamps for reliable power transfer. 3. Easy installation. Replace the standard screw with the M8 post; the original top screw can also be reused if desired. Hand-tighten the posts and, if needed, snug with pliers to avoid over-tightening. 4. Use in solar power systems with large inverters, where higher post clearance and robust clamps improve reliability. 5. Use in multi-point DC distribution panels in workshops, cabins, or off-grid setups for dependable power transfer. 6. Use in RV or marine battery banks to secure heavy clamps across multiple posts for solid connections.
