I have the SCA 66g. My tank was off square so I made sure to take all kinds of measurements and they nailed it for a perfect fit.
Thanks Jimbo! Glad it fit great!
I plan on ordering a lid soon for my 36"x36" rimless tank and have a question. I assume we measure the internal dimensions of the glass and not the exterior dimensions?
You are correct Maximus. Internal dimensions is what we need. The same applies for any overflow boxes within 1/4" of glass top edge as well as any items you need cutouts for such as light mounts. Those dimensions should be taken from inside the glass surfaces also. We are very extensive on the back end with ensuring the measurements we have from you...including oft forgotten cutout needs...are complete before we program and cut your lid. Let us know if you have any other questions!
