Singel tank adapter, Harness distance?

[the_dragon_no1]

Designing and laser cutting my own backplate. But wondering if there is a industry standard for distance between the two mounting holes thru backplate for twins/or adapter?

Want it to be able to use with a adapter as well

The way you phrased what you are asking for is a little bit confusing but...

The industry standard accepted and followed by most manufacturers for plates and single tank adapters (STAs) is to drill11-inches on center....some manufactures/brands will make a slot for the lower bolt and drill 2 or 3 holes for the upper bolt so that wings and trim can can be adjusted vertically on the plate...but typically the top bolt hole to the top of said slot will be 11-inches on center as if the top of the slot was drilled as a bolt hole.

The grommets on the center panel of wings are typically placed 11-inches on center between corresponding grommets (for example where there are multiple grommets at the top and bottom: the top-most upper grommet and the top-most lower grommet will typically be 11-inches apart and the rest will follow suit).

The biggest issue is the slots in a wing for tanks straps compared to the slots in a plate or STA....there is no universally accepted standard for this. I prefer wings like Dive Rite, HOG, and DGX, that have long slots that can be readily used with nearly any backplate or STA setup.

Thanks! Edited my post!

Your post is much clearer now....everything I wrote that discusses spacing still applies. The industry standard for back plates, and therefor STAs, is 11-inches on center (center of hole to center of hole).

11" OC as said above, you can thank Lamar Hires from Dive Rite for standardizing that back in the 80's.
