Exactly what we needed.
My partner is Immunocompromised and we were tired of our apartment allowing contractors to enter our home to perform work orders without notice or consent upon arrival. This is just what we needed to place on our front door. Since it's placement, contractors have made sure to call us prior to attempting to enter. I can't promise this will work for others as effectively, but it did the job for us. Thank you!
