Greenlight's "VXV" Vented Leash Plug provides full time G-VENT venting of your EPS surfboards, Stand Up Paddle Boards, and hollow wood boards without an extra part to install in your deck.
EPS boards contain very small air pockets between the foam beads which expand and contract with changing temperatures. If a board is dinged while surfing and water gets in, additional heat (leaving your board on the beach or in a hot car) will cause the water to change phase in to steam and exert pressure on the fiberglass skin - pushing the glass away from the foam (delamination).
The VXV Version 4.0 is the slickest solution to relieving internal pressure in boards - venting EPS surfboards, SUPs, and hollow wood boards.
The G-Vent's poly mesh screen size allows air (steam) out of the board to relieve internal pressure but will not allow water molecules in! No need to open and close the vent as needed in other surfboard venting systems. Just install and forget it...
