This prefabricated plywood template with a 3/4″ plywood backing makes drilling holes for the H2Overflow®, Siphon Stopper®, and Stealthbox® easy. This can be used to install H2Overflow®, Siphon Stopper®, or Stealthbox® on an existing fish tank, or positioning it yourself when factory predrilling is not an option.
- Template Only: includes just the wood template.
- Kit: includes the wood template and the appropriate glass hole saws for the selected components.
Since glass Glass Hole Cutters do not have a pilot hole or a mandrel, it is very important to use a template to keep the hole centered.
It is recommended to clamp the template firmly with a fresh piece of backing for each hole (just keeping rotating and flipping the backing after each hole) to prevent chipping the glass on the other side. Also, use a coolant (water) while drilling.
