Glass-Holes 700gph Overflow Kit specs

[cubanheat1]

Hello,

Looking to find out the exact size of the overflow box hole for glass-holes 700gph kit. I know the hole for drilling the tank is 2 3/8" while the bulk head and fittings are 1.5". What is the size of the hole on the over flow kit? 2" or 2 3/8" like the diamond bit?

Let me know.

It might be best if you call them to get that info as most anyone here who has that would have already put a bulkhead into the hole and cannot measure it any longer to give you accurate info.

If you find out, can you let me know the info as well? Thanks.

its 2 3/8 like the bit, infact you have to drill it yourself.

i use 2 x 700 kits on my reef the work super and I will definetly use them again.
