Frequently Asked Questions
What BCDs is the Seac Single Tank Adapter compatible with?
It is compatible with the Seac Modular BCD (product code 0420037) and the Seac Modular Max BCD as a counterplate in Seac's Modular backplate system.
How does this counterplate attach to the Modular backplate?
It attaches using Seac's standard-pitch eyelet and bolt mounting hardware, the same system used to swap backplates on the Modular and Modular Max BCDs. This keeps the counterplate interchangeable with other backplate options in the Modular system.
Is this part the same as a Seac backplate?
No, it is a counterplate, not the main backplate. Seac designed it as an interchangeable component that pairs with the Modular backplate assembly on the Modular and Modular Max BCDs rather than replacing the backplate itself.
