Housing issue

Gang, I bought this awesome 128 Gallon terrarium for my Cali-King Khyan, which he loves. However, the front has this divot where he can climb up and slitter across. The issue is that he then falls. It's two feet high and he's a little boo at only 1lb. I worry about is falls so I put strong gorilla tape across the divot to block him from getting up there. Is this ok?
Thanks!

If the tape is inside the enclosure then it needs to be removed immediately.

I would either find another method of blocking his access, give him something soft to land on (like fake plastic plants), or give him more stuff to hold on to so he can climb up and down with less risk of falling.

Yep NO tape in an enclosure EVER

Got it, Thanks! Tape has been removed. I put down baby blankets which are a hit! He can hide in them! I'll be sure to launder them frequently.
