The world's first No Trespassing sign engineered to slide directly onto your existing T-post. Hardware included. No hassle. Just protection.
Traditional signs require drilling, zip ties, or awkward mounting hardware. We designed Whack-A-Sign from the ground up to work with what you already have — the standard T-post.
Our patented bracket slides over the top of any T-post and locks securely in place. It won't spin, slide, or blow off. Ever.
Installation so simple, you'll wonder why no one thought of it before.
Any standard metal T-post works. Already have them on your property? Perfect.
Position the sign over the post and secure with the Allen wrench & screws (included with each sign). Takes about 2 minutes.
That's it. Your property is now marked with a sign visible from over 100 feet away.
Every detail engineered for durability and visibility.
Allen wrench & two screws included with each sign. Simple 2-minute install on any T-post.
Safety orange that stands out against any landscape, visible day or night.
Won't fade, crack, or degrade in direct sunlight. Built for years outdoors.
Weatherproof construction handles rain, snow, and extreme temperatures.
