When this arrived, the UPS man told me, \"It's too heavy for you to carry,\" and I assured him I was going to use it right there on my front porch. Once I got the plastic covering off it, I slid it into place and it fits flush to my wooden threshold now that I've removed the metal plating from having had a screen door installed years ago. Now that I'm in my mid-sixties, I don't need anyone spraining an ankle (myself or friends) stepping on or down from my threshold, so I'm \"safety proofing\" and with this friends with walkers will have an easier time coming in and out, as will any ambulance gurney if I have to go to the hospital. I am in the process of opening my home up to the \"empty nesters\" group in my church for social activities and this will make it easier for those with canes and walkers to come into my front door without any risk of falling or slipping. Best buy of 2024. I am totally thrilled. A+++++, 2 thumbs up, and 5 stars all the way!
