Overflow Box with lid

Unique back cut corners allow for one piece construction with tight 90 degree corners. Slots are 3/16″ wide x 1″ tall and include interior bottom slot tapers to minimize noise.

Overflow boxes are enclosed on four sides, allowing you to provide overflow and surface skimming capabilities to a wall drilled tank without going all the way to the bottom of the tank.

• Made from 1/4″ black cast acrylic.
• 90 degree back cut corners. These allow for one piece construction with smooth, tight and seamless corners.
• Back beveled slots. The backside of each slot is tapered at the bottom to channel water downward. This makes the overflow much quieter (silent in most cases) than comparable non-beveled overflows.
• Recessed bottom joints for maximum strength
• Recessed lid for positive fit
• Lid vent holes to minimize noise
