We realize that the connectors, options and actual test procedures of one customer are entirely different from that of another. In fact over the past 10 years we have never had an identical connector and option configuration between customers! We made it easy with our precision machined I/O output panels to get standard delivery of your "custom configured" enclosure! It goes beyond connectors and options. If you need a special configuration, a different size or door configuration, talk to us! The entire line of STE enclosures has evolved from just that, the needs of people like you!
