Grey Retro-Fit Vent
The Grey Vent Plug is used for venting EPS boards. The vent element is "self-venting" which means there is no need to open and close it after installation.
This product comes with a limited warranty. Select the Casica-Gore product if you prefer a vent with lifetime warranty.
Installation requires a 1" forster bit or short-bit holesaw.
Screw size: M12x1.5
