Slides on.
Stays on.
The world's first No Trespassing sign engineered to slide directly onto your existing T-post. Hardware included. No hassle. Just protection.
Free shipping · Allen wrench & screws included with every sign.
Engineered for the T-post.
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.
Three steps.
Everything included.
Installation so simple, you'll wonder why no one thought of it before.
Find your T-post
Any standard metal T-post works. Already have them on your property? Perfect.
Slide & secure
Position the sign over the post and secure with the Allen wrench & screws (included with each sign). Takes about 2 minutes.
Walk away
That's it. Your property is now marked with a sign visible from over 100 feet away.
Every sign knows
whose land it is.
Molded into every Whack-A-Sign is a unique QR code. Scan it and the sign becomes a live page you control — owner, contact, permits, lease info, whatever you want the world to know. Edit it any time. The QR never changes.
