Dual-purpose slimline gender changers allow mismatched D-sub connectors to mate and are panel mountable to pass cables through a bulkhead. The low profile design reduces leverage strain on overstressed computer ports and is fully shielded for electrically noisy environments. Universally designed for serial or parallel applications. Kit includes 8 adapters DB9, DB15, DB25 and DB37 sizes, each in male-male and female-female versions
