Abstract
Abstract A gasket comprises an edge, a first end and a second end bounding the edge, and a plurality of slits spaced between the first and second ends. At least some of the slits are at one or more oblique angles to the edge. Therefore, a reduced risk of snagging is present when mating one gasket with another with a sliding motion. A method for installing a first electronic device adjacent to a second electronic device comprises coupling a first gasket to the first electronic device and coupling a second gasket to the second electronic device. The first device is placed near the second device such that the first and second gaskets contact with a sliding motion. When in contact, the slits of the first gasket are not parallel with the slits of the second gasket.
