L-COM's DGB9MF slimline socket saver, DB9 Male – Female.

Dual-purpose slimline socket savers extend the life by taking the abuse of frequently mated D-sub connectors used on expensive cables and ports. They are also panel mountable to pass cables through a bulkhead (see panel mount tips). 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.
