© Street Sign USA Aluminum Post Mounting Base Data Spec



Aluminum Sign Post Mounting Base is compatible with all our 2lb per foot U Channel & Square Sign Posts.  Our 2-3/8" Pipe Posts will work but holes have to be drilled in the post to mount it.   1.12lb per foot U Channel posts will not fit the base stub and will not work.


*Hardware to mount post to stub and stub to base included.  Stub is included with base.


For permanent mounting applications into concrete, galvanized lag shields, washers and screws in 3/8" are recommended.  For asphalt, 12" galvanized spikes are recommended and can be found in most hardware stores.
