Extension support kits are used to connect the back end of your electronic component, drawer, etc. to the rear rack rails of your rack frame, enclosure or shipping case. If you're using a Star Case steel or aluminum rack, you can mount your support kit vertically extending downward and use the link strips to provide suspension or hanging support. No matter whether you're seeking horizontal support or vertical hanging support, this option is sure to hold your rack mount component, drawer, etc. firmly in place with maximum support no matter what the load. These kits are available in a 7" or 19" length depending on the depth of your rack enclosure, component, or drawer. Both sizes have holes the entire length of the support bracket giving you the ability to adjust the length to fit your component properly.
