Best used as a scupper stopper in the cockpit of a sit-on-top kayak. The large end is 1 and 1/16”. The small end is 15/16". May be used as an Ocean Kayak “extra small” scupper stopper in some cases. *SIZE CHART WINDOW* Add 18” of cord for one dollar to use as a leash if needed. 
Important: Rubber stoppers have a HOLE. The hole is for an optional 18-inch cord used for securing the cork to your kayak and/or for easy removal. The cord fits very snug and will not leak. This adds one dollar to the cost.
Corks with holes can be used as dive flag pole mounts. A 12-inch tube can be inserted for use as a breather vent for surf skis. The hole can be filled with GOOP brand sealant-adhesive if so desired. Please select your option below.
