Straight from the brains at Impact LED, the Speedy Mount Bracket is an EMC installers best friend.  No more fabricating brackets on-site.  Whether you choose to bolt/weld the EMC unit(s) to the bracket before lifting, or mount the brackets first and then attach the signs - the choice is yours but the convenience is clear.  Square brackets, built to fit a number of pole sizes - ready to install & build to last.
