Safety first, right? This Caution Tripping Hazard sign is one of those things you don't think you need until someone takes a tumble. The 7x10 inch size is perfect - big enough to see clearly but not so huge it's obnoxious. It's made from this super durable 55 mil HDPE plastic that can actually last up to 2 years outdoors without fading or cracking. The digital printing is really sharp and clear, plus it has this protective over-coating that keeps it looking good. I love that they rounded the corners - no sharp edges to worry about, and it just looks more professional. It comes with pre-punched mounting holes so you can easily put it up on walls, fence posts, doors - pretty much anywhere you need to warn people about tripping hazards. Whether it's for a construction site, warehouse, office, or even your own business, this sign does exactly what it's supposed to do - keep people safe and prevent accidents. It's OSHA compliant too, so you're covered for workplace safety requirements. Seriously, for the price, it's cheap insurance against someone getting hurt and all the paperwork that comes with it. Just mount it where people can see it and you're good to go!
