Offical name is the up fuker.

You dont need webbing, we use a bit of tapered 4mm. In the board you need to drill a hole all the way through the board (just big enough to fit the line through) then on the port side you need drill a fairly large holl a few mm in to the board so that the knot can sit in it and not obsrtuct the board. In the case cut away abit of the carpet where the line runs into the slot.

On our infusion we run the line under the tramp and have a eyelet on the starboard side where it comes out and then goes through a block and ties off on the toe strap.
