Here are the photos I promised. It was hard to get a good photo shot to show the size of this thing.
This is the intank portion of the overflow
Here you can see the two U tubes that take teh water out of the tank
Here you can see the outside portion of the overflow. The sponge's I have removed
The overflow measures 14" in lenght and is 4" deep on the outside portion. There are two 1" return lines and two 1 1/8" U tubes.
The entire overflow is made of acrylic except for the two bulkheads and the overflows.
Overall this is a very nice overflow for the price.
