Allows 4-post mounting of server equipment made for shorter server racks (e.g. fitting 15" audio drawer in a 24" server rack). Haven't done full load testing on these extenders, but the firmly hold my 12kg printer + sliding drawer.

The model has the following pairs of rack extenders:

• 1u - 6in Rack Extenders
• 1u - 4in Rack Extenders
• 1u - 2in Rack Extenders
• 2u - 6in Rack Extenders
• 2u - 4in Rack Extenders
• 2u - 2in Rack Extenders

Motivation:

Sometimes rack equipment is meant short audio racks but is way better quality than deeper equipment (or only available for shorter racks.) Then you go on amazon and find out the cheapest rack extender is $60. Now you don't need to pick between dangling equipment or overpriced sheet metal.
