Problems solved by technology

While these covers do a good job of keeping liquids from flowing into the drain, heavier or larger sized units can be difficult to handle and position due to the lack of stiffness across their width
Their inherent stickiness can also make removal difficult as there are no features to facilitate gripping the protective cap with sufficient force to remove it from the drain

Abstract

Protective drain covers are disclosed, including stiffening members at one end or at opposing ends to increase rigidity in one direction while leaving the other direction flexible. The increase rigidity in the one direction improves the ability to handle and accurately position the protective drain cover for use, while the flexibility in the other direction allows the protective drain cover to berolled up for storage and future use. The stiffening member(s) can be used as hand-holds to assist in the placement of the heavy protective drain cover and then removal of protective drain cover afteruse.
