Aluminum Plates on 2 lbs./ft U-Channel Post
Ribbed aluminum plates help to prevent sign bending and distortion during installation of signs to posts. The added strength from the plates prevents damage from the over-tightening of mounting hardware. Ribbed aluminum plates are sold in packages of two, one set for each post-mounted sign.

What's the purpose of these Plates?
Their purpose is to prevent signs from being bent or distorted if you over tighten the mounting bolts when installing signs onto u-channel or square posts. These aluminum plates are not typically a requirement, but we recommend their use.
