What you need:

  • Three 2.75" by 5/16" bolts
  • Three 5/16" flat washers
  • Six 5/16" threaded nuts
  • All hardware should be corrosion resistant.
  • Two 1/2" wrenches
  • One u-channel sign post
  • One Post Alert™

Installation Precautions

Remember that the MUTCD sign enhancement spec requires the post enhancement device to be the same color as the related sign and to be fastened directly under the sign with no more than 2 feet off the roadway elevation. If using the diagonal object marker style Post-Alert™, note that the diagonal lines should point downward toward the side in which the motorist should travel. If your sign is installed properly, it is fastened against the rails or flanges of the u-channel post.

U-ChannelInstallation Steps

Step 1


Align the Post-Alert™ to the back of the u-channel post at the preferred height.

Step 2


Align the holes of the Post-Alert™ to those of the post and mark their locations or place the 2.75" bolt through the holes from back to front.

Step 3


Thread the first nut onto the bolt approximately half way down the threads. Repeat this for all three bolts. *Note: This nut is to insure that the Post-Alert™ is not over-tightened.

Step 4


Push the top bolt end through the top pre-drilled hole in the Post-Alert™. Place the flat washer and then the nut onto the bolt and thread it hand-tight. Repeat this for all three bolts.

Step 5


Use a 1/2" wrenches to tighten all three nuts. Be careful to not over-tighten and insure that the Post-Alert™'s shape does not notably deform from the pressure!

Completion


Now your Post-Alert™ is securely fastened to your u-channel post and will improve both the visibility and conspicuity of the sign and it's post, making your roadways safer for both pedestrians and motorists!

Round Post Instructions - Bolting Directly to Post

There are two primary ways to attach the Post-Alert to a round post. The easiest is to attach the Post-Alert by drilling and screwing it directly to the post. Alternately you may attach the Post-Alert with modified round post brackets. Brackets should be modified so that they sit flush against the inside of the Post-Alert without significantly deforming it.

  • Three Sheet Metal Screws
  • Three Flat Washers - Size is dependent upon screw selection
  • Drill Driver for screws - Size is dependent upon screw selection
  • Marking device
  • One Post Alert

Installation Precautions

Remember that the MUTCD sign enhancement spec requires the post enhancement device to be the same color as the related sign and to be fastened directly under the sign with no more than 2 feet off the roadway elevation. If using the diagonal object marker style Post-Alert, note that the diagonal lines should point downwardly toward the side in which the motorist should travel.

Installation Steps

Step 1


Place the Post-Alert flush against the front of the post so that the reflective sheeting is facing the same direction as the sign.

Step 2


Holding the Post-Alert in its final place against the sign post and mark where the Post-Alert's pre-drilled holes align to the sign post.

Step 3


Remove the Post-Alert and drill holes into the sign post where marked from the previous step.

Step 4


Place the Post-Alert flush against the sign post lining up the Post-Alert's pre-drilled holes with the drilled holes on the sign post. Place a flat washer on a sheet metal screw and screw it in snug. Repeat this process for the remaining pre-drilled holes.

Step 5


Check all the screws for any need of further tightening. Be careful to not over tighten and insure that the Post-Alert's shape does not notably deform from the pressure.

Completion


Now your Post-Alert is securely fastened to your round post and will improve both the visibility and conspicuity of the sign and it's post, making your roadways safer for both pedestrians and motorists!

Round Post Installation Steps

Step 1


Attach the primary halves of the modified round post brackets to the inside back of the Post-Alert™ by pushing the sign bolt through the primary bracket, and then through the Post-Alert™'s pre-drilled holes.

Step 2


Add flat washer over the end of the bolt and thread the nut over the end. Tighten first by hand, and then tighten with the wrenches. Repeat this process for the rest of the brackets. Use at least two brackets for each Post-Alert™.

Step 3


Place the Post-Alert™ with installed primary brackets around the front of the sign post, ensuring the Post-Alert™ reflective sheeting is facing the same direction as the sign.

Step 4


With the primary brackets around the post, attach the second half of the bracket assembly to the primary half and bolt the two pieces together. Hand-tighten the bolts.

Step 5


Make final adjustments to the direction and height of the Post-Alert™ and tighten the bracket assembly to the pole with wrenches.

Completion


Now your Post-Alert is securely fastened to your round post. It will improve both the visibility and conspicuity of the sign and it's post, making your roadways safer for both pedestrians and motorists!

Square Post Instructions

There are two primary ways to attach the Post-Alert™ to a square post. The easiest is to attach the Post-Alert™ by using aluminum anti-theft drive rivets. Alternately, you may attach the Post-Alert™ with 2 3/4" by 5/16" standard sign bolt hardware.

Square Post Installation Steps

Step 1


Place the Post-Alert™ flush against the front of the post so that the reflective sheeting is facing the same direction as the sign.

Step 2


Adjust the direction and height of the Post-Alert. Align the pre-drilled holes of the Post-Alert to those of the sign post.

Step 3


Push the drive rivet with the attached nylon flat washer through the Post-Alert's pre-drilled holes and through the sign post holes.
