Abstract: A handle adapter includes a sliding member, a cap, and a handle member. The sliding member includes a first slide channel and a second slide channel defined on opposing sides of the sliding member and parallel with one another. The cap includes a top cap channel, a first side cap channel, and a second side cap channel. The first side cap channel and the second side cap channel are parallel with one another and perpendicular relative to the top cap channel. The cap is aligned with the sliding member along a plane. The handle member includes a top end and a bottom end. The top end is coupled to the cap and the bottom end is coupled to the sliding member. The handle member is substantially protruding beyond the plane.
