I want to hang some decorative metal Fret items and a small single shelf on front of brick home. The shelf is not very big but is metal- 19”tall X 16” . DH does not want to damage brick and is concerned that hanging into the mortar joints w/ screwin anchors is not strong enough. Are there any hangers that will do th job? I have included photos
