  • Corner triangle overflows are intended for installation in a corner of a rectangular tank, usually in the back. One edge of the box attaches to the back of the aquarium and the other edge attaches to a side wall. Tenecor triangle overflows have 45 degree beveled vertical edges for better fit and seal and can be used in any corner.

  • 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 a closed bottom overflow which means it does not need to be sealed to the bottom of the aquarium. The bird's nest design allows you to adjust the mounting height as desired.

  • Product Features

    Tenecor overflows are precision fabricated using CNC equipment. Your overflow will have corners that are true and square and mounting surfaces that are flat and level. Inlet slots will be uniform and precise.

    How to measure for the perfect fit

    If your aquariums has 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 overflow box will be fabricated to the size you select. For rimless tanks, measure to your preference.

    Things to remember

    -The size of box you select is the size we make the box. You can expect tolerances of +/- 1/16".

    -Dimensions are external measurements.

    -Trapezoid width is measured where it mounts to the aquarium wall.

    -Water inlet slots are approximately 1/4 inch wide and extend down approximately 1-1/2 inches from the top of the box.

    Holes & Drilling

    Overflows are PRE-DRILLED with a 1-1/8" hole four inches down from the top edge of the overflow. Please notify us with your order if you would like your overflow undrilled or drilled a different size.
