Why Whack-A-Sign

No Trespassing Signs, done right.

Slides on in 2 minutes

No drilling, no zip ties. The patented bracket slides over any standard T-post and locks with the included Allen wrench and screws.

Impossible to miss

High-visibility safety orange that stands out against grass, dirt, or snow — clearly readable from over 100 feet away.

Built for the weather

UV-protected, weatherproof plastic that won't fade, crack, or warp through years of sun, rain, and snow.

A sign that talks back

Every sign carries a unique QR code — scan it to see whose land it is and who to call, editable any time.

The Technology

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.

Questions

Straight answers.

What makes Whack-A-Sign different from a normal No Trespassing sign?+
It's the only one engineered to slide directly onto a T-post — no drilling or extra hardware. It locks on so it won't spin or blow off, and it carries a scannable QR code you control.
How is it installed?+
Slide the bracket over the top of any standard metal T-post and tighten the two included screws with the included Allen wrench. About two minutes, no tools of your own required.
Will it hold up outdoors?+
Yes. It's molded from UV-protected, weatherproof plastic built to sit on a fence line for years without fading or cracking.
How much does it cost?+
$14.99 for a single sign with free shipping, with volume pricing on boxes of 10 and 64.
