Abstract: A wall mountable holder may include a base portion, a first arm, and a second arm extending outward from the base, where each of the arms may extend to a distal end spaced away from the base. Additionally, the holder may include at least one groove extending downwardly from an upper edge of at least one of the arms. The holder also may include a tab extending inward at a distal end of at least one of the arms, the tab including a leading surface angled inward and rearward from proximate the distal end, and a trailing surface angled outward and rearward from the leading surface. An opening may be formed between the arms, proximate the distal ends, such that the opening may be narrower than a spacing between the arms at each point between the base and the opening.
