Product Description

No Trespassing Signs Put You In Control.

Signs are made from 3M's reflective engineer grade film.
Signs are fabricated from aluminum that is rigid and durable. Rust-free, but lightweight, these signs outlast steel or plastic signs.
Signs have predrilled holes for easy installation. Signs can be installed onto a post, fence or wall.
These municipal quality signs are great, also, for parking lots, garages or visitor areas.

Sturdy signs.

The signs were nice and sturdy as I had hoped. Just as sturdy as city signs are. I felt the price paid was reasonable as well. 5 stars for me.
