Product Information
The Seac Aluminum Backplate for Modular BCD is a black, aluminum backplate component built as a replacement or spare part for the Seac Modular and Modular MAX buoyancy control device systems. It is sold on its own, not as part of a complete BCD, and is identified under SKU 0450009.
Who it is for
This backplate is for divers who already own a Seac Modular or Modular MAX BCD and need a replacement backplate, a spare for travel or redundancy, or a component to rebuild their current rig. It suits divers who use the Seac Modular backplate-style system.
Key details
- Constructed from aluminum.
- Finished in black.
- Sold as an individual replacement or spare component rather than as a complete BCD.
- Identified by SKU 0450009 and MPN 0450009000000A.
Compatibility and sizing
This backplate is designed to work with the Seac Modular BCD and the Seac Modular MAX BCD. Because it is a system component, confirm your existing BCD is a Seac Modular or Modular MAX before ordering, since fit is system-specific.
