The MTPH and TTPH Harness Series utilize standard front panel assemblies, a 4 foot cable harness, and our standard back panel assemblies. Available in a wide variety of configurations, all are terminated to our PPTs on the back panel. Primarily used where the back panels must either be mounted into a rack, or brought back to the front for easier access. Custom cable lengths can also be supplied. Contact the factory for details.
