We were looking for a 1U 19" Rackmount LCD Keyboard console for our Flight Simulation System. KVMSwitchTech promptly responded to all our questions. We purchased several NRKD-KVM-19 Rackmount Console units from them and are very happy with the performance. Keep up the good work.

KVMSwitchTech helped us with a 1080p Rackmount Console with integrated 8 Port USB KVM Switch for our CNC Machines. The product works great and the staff is very friendly. I would recommend this Company.

Knowledgeable, experienced and courteous staff. We needed Fiber Optic Extenders with EMI shielding to avoid interference in signal transfers. KVMSwitchTech worked with us to design a DVI Fiber Optic Extender customized for our application. Thanks for all your help.

Rack LCDs for one of our newer locations were required for data monitoring. The light weight and short depth design of the Rackmount LCD Console was exactly what we were looking for. In addition, the product's streamlined and durable construction ensures its longevity and reliability in our environment. These guys are pros and know what they are doing.
