Sold in packs of two, these plug have a slight taper for a tight fit when installed. This is better than universal plugs with an extreme taper because those plugs tend to not hold as secure which makes them prone to leaking and becoming dislodged easily. Plugs are easily removed using thanks to a pull cord loop. Made in the USA When measuring… Be sure to check each scupper hole to be plugged. They can and do vary from hole to hole. Measure to the nearest 1/8” at the section of the scupper hole where it is completely round and begins from a straight cylinder wall. Select a plug size that has your scupper hole measurement somewhere near the middle of the taper range. For example if your scupper hole is 1-1/4”, you would want to select our 1-3/16” - 1-7/16”. This means that when the plug is installed, it will be approximately halfway in. If a larger plug is selected it will sit too high and be easy to be knocked out. If a smaller plug is selected it may sit lower but it may also not be large enough to press tightly in the scupper hole for a proper seal.
