Shapers custom Base "for GORE™ Protective Vent) for easy installation. No more taping the surfboard, just rout out a hole and drop in the base that is pre-tapped for your convenience.
*Please note: BASE ONLY
The Diameter of the base member is 32mm, we would recommend to drill a 34-36mm hole to ensure there is efficient amount of resin around to base. The base member does not have a pre-drilled hole to allow for air to release. This is due to base member having to be install with resin, having a pre-drilled hole which is not covering correctly can allow resin to flow into the base member and then fill in the tapped thread. Therefore once you set your base member and resin has gone off, you then simply drill a 3mm hole through the base member.
