The MAPEX RM-MABS-Q-DH Biposto mounting backrail is the structural link between multi-tenor arrays and Biposto style carriers in the Posto Series. Its dual-hook receiver geometry locks the array firmly in place, preventing lateral shift or unwanted tilt during the most dynamic marching movements.
- Biposto dual-hook receiver design prevents lateral and rotational array movement
- Designed for direct compatibility with RM-MABS-Q and RM-MABSP-Q Biposto carriers
- Works with RM-MASH-Q Stadium tenor stand for stationary applications
- Aluminum construction keeps the overall system lightweight without sacrificing rigidity
- Standard-spec backrail included with Posto Series Biposto tenor carriers
- Available as a standalone replacement or additional unit for multi-section inventory
