No Rung Drop-Out

Labor-saving Solution for Ladder Tray Drop-outs

A customer requested a ladder tray drop-out solution that would not require the on-ladder removal of dividers and cables, as this was deemed a safety issue. It should also allow the installer to easily locate the drop-out along with the tray with greater flexibility and without the need to attach to the rungs of the tray. The patented No Rung Drop-Out (NRD) was created to allow the installer to SAFELY and EASILY add a drop out wherever, and whenever necessary.
