Bought this vent and discovered that there are only 2 pre-drilled nail holes on base. Was this done for a specific reason or should I pre-drill more nail holes into the vent?
Thank you for your question regarding the 636AL roof cap. The pre-drilled holes are to assist with positioning the unit. You can pre-drill more nail holes in the roof cap. If you have any further questions, please call Technical Support at 1-888-336-6151.
