Post & panel signage stands as a cornerstone in the world of sign making, offering a trifecta of effectiveness, simplicity, and durability in installations. The key to achieving seamless installations lies in understanding and utilizing a set of fundamental components, including:
- ACM / Aluminium sign blank with a sign channel
- Aluminium or Steel CHS Sign Posts
- Anti-Rotational Sign Clips (U clips)
- Sign Post Cap
With these four components in place, you have all of the essentials for creating a robust post & panel sign system. However, one common challenge faced by sign installers is arriving to site with the incorrect size sign clips.
Often Signs are replaced on site and will use the existing sign posts to mount the new sign panels. This means the existing posts will need to be accurately measured to ensure the correct sign clips can be ordered.
The following measuring techniques can be used to identify the post size.
Technique 1 : Measure the Diameter
The diameter is the most important measurement when looking to order the correct sign clip. Sign post clips are listed and sold in diameter sizing. For example a 76mm sign clip will suit a 76mm diameter post.
To measure the post diameter extend the tape measure from one side of the hollow section to the opposite side, passing through the center of the post. Ensure that your measurement is taken perpendicular to the sides for accuracy.
As many signs are being fitted on existing posts, measuring the top profile can be extremely challenging. In these situation, technique 2 will be much more effective.
Technique 2 : Measure the Circumference
If accessing the top of the post is challenging, measuring the circumference offers an alternative route to determine the required diameter. Wrap a soft tape measure around the post to find its circumference, then divide this figure by 3.14 (Pi) to get the post diameter, corresponding to the needed sign clip size.
Example Calculation: If the post measures 238mm in Circumference (23.8cm):
This indicates a 76mm clip is required.
