Blackthorn has Solid Plastic and Steel machined lettering plates for all of your molds that require permanent cast in identification.

We have hundreds of existing molds with generic labels and messages to choose from (inlet/outlet, tank gallons, individual letters and numbers, etc).

If we do not have a mold for what you need, or you want a unique message or logo, we are happy to make a brand new mold to your EXACT specifications!

Multiple mounting options are available: Bolt-On, Magnetic, or Hand-Stamp.
