So I recently bought a 3 story ferret nation to find out that my gliders slide right through the bars, my question is does anyone house adult gliders in a ferret nation model 182? Cause mine are still young and I don't know if I should keep it until they can't slide through the bars or just sell it

Unfortunately the bars are too far apart on Ferret Nation cages even for adult gliders. If you like the design of your cage, the Critter Nation is exactly the same except the bars are horizontal instead of vertical, and are only 1/2" apart.

You can just zip tie plastic hardware cloth.
Like the one used to make the PVC cages.
