That one is not custom, it is what Sea star supplies.
It is also standard sea star overflows, and drain pipes.
The 2" extention on the pipe is not glued so you can cut it to your needs.
Cut at about 3/4" below the bottom of the overflow fingers, for a pump that runs about 500 gph, the bigger the pump the more you cut it down.
If you are unsure, leave as a dry fit, there is no need to glue that joint.
I like to leave them high enouph to leave a definate drop in water,making sure you are surface skimming well, but not enouph to make noise.
On sea star or any euro braced tanks, it is also nice to run the water line in the tank high enouph to just touch the bottom of the bracing.
If not, it will develop salt creep and block light.
The hole through the overflow is meant to have a threaded street 90 fit into int with another 90 off of that...Or some locline.
This is done because the overflows are glass inside and cannot be drilled that close to the edge.
This will prevent backsiphon down to that hieght.
