2U Rack Reducer

Not all rack cabinets have the same depth. Some rack cabinets are shorter, some are deeper. That is the same with rackmount equipment. You never know what you are going to get until you actually install it in your cabinet. If you are lucky, it fits perfectly inside your rack cabinet. The chance are that your cabinet might be just a couple of inches deeper than your rackmount equipment supports. In this kind of situation, you will need a RACK EXTENDER. A rack extender is a pair “U” shaped brackets design to extend a section of the rear vertical mounting rails to reach your rackmount equipment's mounting brackets.

IAB103 is ideal for this situation when your rackmount equipment cannot reach your rear vertical mounting rails. IAB103 offers you additional 3” extension depth you need to properly install your rackmount equipment. IAB103 is engineered for use in any standard 19”, 23” or 24” rack cabinets. It is constructed with heavy duty 14 Gauge steel with a black powder paint finish. It has oval holes on one side supporting M5, M6, 10-32 and 12-24 rack screws. The square cage nuts holes on other side supports standard cage nuts such as M6, #10-32 and #12-24 for heavier weight support.

Our unique design allows customer to have direct access to mounting rack screw with bracket depth as short as 1.1”. Unlike design from other manufacture, angle screw driver from side of bracket is the only way to access mounting rack screws. Usually this installation method can lead to stripped screw head or loose screws.

IAB103 comes in different sizes. It supports rack space from 1U up to 4U rack space. Please use our RACK extender selection guide to choose the right extender for your application.

We offer complete lines of rack extenders from 1U to 5U with depth ranging from 1.1” to 8” deep
