FMR Audio 1/3 Rack Tray Adapter

This custom-made "rack tray" is specifically designed to hold up to three of our 1/3 rack products in a "1U" rack space.

Secure mounting is accomplished by utilizing a US-standard 10-32 "rack" screw that is placed through a dimpled hole in the tray up into a captive 10-32 nut built into the base of our 1/3 rack products. Since all of our 1/3 rack products have four rubberised feet, tightening the screw causes the unit to compress the feet, thereby holding the unit firmly and resisting loosening due to vibration.
