Have you used our AT1200S or 

27-9

AT1200S-2 Air-Powered Twin Sausage Guns to fill joints with 2-part silicone on highways, bridges or parking garages?

   Many traffic joints are 3/4" or wider.  But for those that are narrower, consider adding one of our 32-series metal nozzles to reduce the diameter of static mixing nozzle 484-146-6166F4M from 3/4" ID to 5/8", 1/2", 3/8", 1/4" or 1/8" ID.

   You'll have more control and make less mess.
