Is this the right overflow box?
Tenecor wall mount overflows are intended for installation on a single flat surface such as the tank's back or side wall. When mounted to a side wall, the aquarium can be viewed unobstructed from three sides as in a room divider set up. This is an OPEN BOTTOM overflow which means it must also be sealed to the bottom of the aquarium.
We offer many sizes of this design and our recommendation is choose the biggest box that will fit. A bigger box will allow for smoother water flows and quieter operation. Tenecor overflows can also be used as additional filters when filled with bio media and sponges.
We also offer this overflow in a trapezoid style with angled sides instead of the square corners.
How to measure for the perfect fit.
Many glass aquariums have a plastic rim along the top edge. Measure the depth of the tank from the bottom of this rim to the bottom of the tank. Your skimmer box will be fabricated to the size you select. For rimless tanks, measure to your preference.
Please remember the size of the box you select is the size we make the box. Dimensions are external measurements.
Water inlet slots are approximately 1/4 inch wide and extend down approximately 1-1/2 inches from the top of the box. Keep in mind your water level will generally be at the bottom of the skimmer slots.
No charge optional return holes.
We will drill 3/4 inch return line hole(s) at no charge upon request. The hole(s) will be drilled approximately 4 inches from the top of the overflow.
You will be able to submit your request for drilling instructions at checkout.
