Appro stopped selling their 4U 4402 and 4408 chassis leaving many customer scrambling for solutions. CP Technologies provides identical chassis by reverse engineering the original Appro products. The result is customers previously purchasing the Appro 4402 and 4408 chassis now have a reliable source for continued production.
The FAAC Simulation Image Generator profiled above was a modified Appro 4402 chassis. Please note these chassis are available for general purchase from CP Technologies.
