  • The Precision Port Kit consists of 5 parts - a single port tube, one large exterior flared end, one small interior flared end, and two connector rings. These connector rings attach the flared ends to the port. Use an ABS adhesive or similar type glue (sold separately) to secure the port tube, connector rings, and flared ends together.

The Precision Port can be placed as close as 3" from the inside wall of the enclosure. Although, it is recommended to keep it as far away from the inside wall as possible.
