BLUE TONGUE SKINKS

Hello all new here. Here are my questions. I have a AP T8 48 x24 x12. Front opening any suggestions on increase the height of the front lip it's about 2 in high what can use to raise so i add 4 in of substrate. I was thinking of use some corrugated plastic sheet cut to size needed any suggestions or assistance will be much appreciated. Thanks to all who respond be well

Many people do just that with plexiglass sheets

Thanks much appreciated

Plexiglass works well, I also used a piece of wood, I used a 1x4 for mine. If you coat the wood in an animal safe polyurethane it will completely seal it to be waterproof and it works great. I have it on my entire 6x2x2 custom cage
