Abstract: An apparatus includes a first base portion having a first surface and a second surface opposite the first surface. The apparatus also includes a second base portion having a third surface and a fourth surface opposite the third surface. The apparatus further includes a bridge portion coupling the first base portion and the second base portion. The apparatus additionally includes a tether one or more of extending from or coupled with at least one of the first base portion, the second base portion, or the bridge portion.

Abstract: An apparatus includes a first base portion coupled with a second base portion. The apparatus also includes a first backing member extending from the first base portion and a second backing member extending from the second base portion. A first length of the first base portion is equal to a second length of the second base portion and a first width of the first base portion is equal to a second width of the second base portion. A maximum distance between an outer surface of the first backing member and the first base portion is less than a maximum distance between an outer surface of the second backing member the second base portion such that a first space is less than a second space.
