Attachment Kits for U-Channel Posts

Most signs are attached to a u-channel post. And, most use our simple and inexpensive kit (below). For greater security, however, we recommend our Tamper-Proof brackets. These can be installed easily with a normal screwdriver. But, you will need a special tool to remove them. Lastly, check out our post pounder or drive cap. These simple tools can really make a difference.

Worked as advertised! Much better for chain link than strands of chicken wire.

These worked great the only problem was the threading in the metal piece wasn't smooth so I had to work a bit to get the bolts through it. But I got it done!
SmartSign: Thank you for placing your order with us. We look forward to serving you in the future.
