Streamline the time-consuming chore of replacing panels on tanks.

When you need to replace a panel, simply pull the old one out, slide the new one in and you're done. 

Panel is manufactured on 20 mil rigid vinyl and they, as well as the extra sturdy holders, will hold up to years of use and abuse.  Holders easily attach to a post or stanchion with rivets or screws. 

Panels use- 6" black numbers. 
Numbers come- 5 duplicates in a pack.
