Some legacy paratroop doors contain round windows with limited external visibility as compared to the current C-130J paratroop door configuration with a rectangular window. The kit is a quick, direct replacement set of doors with much improved external visibility from a 340% larger surface area window.

The kit contains left and right side replacement doors with integral fold-down observer seats, new negator motor and cable, new hardware, and installation instructions. The replacement doors are the same door that are currently used on the new production C-130J aircraft. This kit is applicable to any C-130 and can be installed at the organizational (squadron) level of maintenance or by any qualified Hercules Service Center.
