Review on 🏠 Hy-Ko FM-6/1 Floating House Number 1 (ONE): 6" High Black - Stylish and Functional Address Identification Solution by Loren Rindfleisch

They are difficult to install in plaster but doable. You will (obviously) need your own masonry drill bit. A puncher is highly recommended. The instructions say to drill 3/16" holes, which I think would pose a problem. I went with 1/4". Worked fine. The plastic dowels went in with no problem, but most of them did broke when applying the numbers. It doesn't bother me too much. I'd be very surprised if the numbers ever showed up. The metal spacers that "float" these numbers are silver. I took another reviewer's advice and painted them black before installation. Very glad I did. Plus they look great. Overall very satisfied.
