Rack Extender


IAB104 provides a simple, low cost solution to enable you to extend your cabinet’s vertical mounting rails inward or outward for your rack equipment. IAB104 is an "U" shaped extension bracket for a standard 19” or 23” rack cabinet. It allows you to extend a section of the cabinet mounting rails to accommodate your rack equipment.

IAB104 is ideal for situation when your rackmount equipment cannot reach rear vertical mounting rails. If you cannot readjust your rear vertical mounting rails, IAB104 gives you additional 4” extension you need to properly installing your rackmount equipment.

By installing IAB at front, it pushes your rackmount equipment outward by 4”. This setup is ideal for mounting LCD monitor or rack equipment which has wider front facing panel. You can also use it as a way to create 2” gap behind filler panel for cable accessing.

We offer complete lines of rack extender from 1U to 5U with depth ranging from 1.1” to 4” deep.
