Standoffs hold your sign off the wall instead of flat against it. That gives the piece some depth and shadow, and it keeps water and moisture from sitting in the gap between the sign and the siding.This listing is a set of 2, which is what most of our signs need. Choose black or silver. If your sign needs more than two, raise the quantity and we will send them out together with the order.Every sign we build is cut from 12-gauge steel, which is 3mm thick. Most online sign shops use 14 or 16-gauge, roughly half the thickness. Ours gets powder-coated after cutting, and that finish is rated around 20 years in direct sun before it needs redoing. Standoffs are the hardware that keeps all that steel sitting properly on your wall.If you are unsure how many you need for the sign you are ordering, ask our team before you check out and we will tell you what that piece takes.Choose black or silver, set your quantity, and add it to the order with your sign.
