A cap fits over the exterior of the pipe casing and grips the outside surface. A plug fits inside the pipe and expands against the interior wall. Caps are faster to remove for routine sampling access; plugs create a flush internal seal.
Our Grip-N-Lock caps are manufactured by Enviro Design Products — designed specifically to solve the freeze-thaw dislodgment problem that plagues standard snap caps in cold climates.
