Case hardened and heat treated componentry that meets GBC and industry standards.
Due to the North American severe and harsh weather conditions that the automatic slack adjusters are exposed to, a series of rust and corrosion inhibitors are used to insure longer life.

To complete the sealing process on GB&C Inc. slacks, only high quality gaskets and thermoplastic resin (TPR) o-rings designed to withstand severe temperature fluctuations and the environment are used.
