What do you call this "overflow Adjuster"

[arowana718]

Hello all,

so my overflow teeth is about 2" and water level is a lowered than what i desired.

Do they make any acrylic pieces where i can just attach on to the inside of overflow teeth so i can "shortens" the overflow teeth to my desired level?

is there such a thing? If so, whats the name of it?
