Get a waterproof seal with our high quality EPDM rubber gasket and nylon spacers.

Perfect for use on waterproof surfaces where your fasteners are puncturing the sealed surface.  Use with or without gasket sealing caulking.

Also useful where attaching the anchor to concrete in climates that have freezing and thawing.  Sealing the holes properly prevents or reduces chances of concrete cracking prematurely from ice expansion.  Not required for wood surfaces.

(Cannot be used with the Caliburn 19/64" x 3 1/2" XL Concrete Screws)
