These high quality plastic house numbers are machined from an orange peel textured marine-grade high density polyethylene (HDPE plastic) with UV stabilizers. This prevents fading and can hold up in most climates. The number height is listed in the title, they are 1/4 inch (6.3 mm) thick, and come with 2 painted-to-match 1.25 (31.75 mm) inch long zinc coated mounting screws and optional 1/4 inch thick matching spacers. *Spacers allow the numbers to float if you choose. If you need to know widths ask me and I can draw them for you to let you know.-To order multiple numbers, add one to your cart at a time, using the back button to add more, then check out after they are all there.-If you need letters and they are not listed choose «letter» and add a note to seller on the checkout page of which letter(s). We can also cut other punctuation or characters if you choose «letter».If you want a COLOR from the image not in the menu, choose white and write a note to seller on the checkout page what color you want.Shipping: International shipping outside the U.S. will be combined and over charges refunded. *Numbers have a cap height of the listed size, but some numbers may be slightly taller because of the way this font is designed. A number 1 is the exact height listed but numbers with curves on the top and/or bottom like the 2, or 8 will be slightly taller in order for the numbers to look proportionate. This is not a defect, but a design technique. The 8,3,0 are tallest at 6.3” tall.To mount them horizontally you want to center them with each other.The «1/2» has a 1 and 2 that are half the height of the listed size so they can be stacked and end up at the listed height.
