I work at an events complex in our local city. We hold many events such as comedy shows, concerts, Christmas parties, fundraisers, and weddings. Since we always have so many things going on, proper signage is a must! Without it, you get a lot of people asking questions when you should be focused on other things.
I recently purchased this stanchion sign holder from HASA Direct on Amazon.
With a removable metal adaptor that can be easily attached to your stanchions. It fits nicely and helps secure in place.
Inside the frame, there are two pieces of plexiglass for protecting your signage. The easily slide in and out at the top of the frame.
The top sign frame is 8.5" x 11" in size and is made of a sturdy metal to keep your signs nicely in place. It can hold signs for just about anything including menus, flyers, directions, upcoming events and more.
This stanchion sign holder is also backed by a 90-day money back guarantee, but I really don't think you will need to use it as this a very sturdy well-made product.
You can find it here.
