News and Notes


  • Planning ahead is usually the best approach to meeting goals. We can help by offering storage of brake valves until orders are required at a later date. Call for details.


  • We offer an educational course and certification for the use of the manual single car test device. Contact us for details or to schedule a class.


  • We are always looking for opportunity to market and distribute products. If you are currently looking for candidates to market your product, we would be interested in speaking with you.
