Editor’s note:
Consider it done, Mr. Newman. Readers, save your unit
time and money by making sure you properly use the shackleless provisions.
Review and use the guidance you’ve just been given. Let your vehicle’s TM,
MIL-STD-209K, and the SDDC TEA website help you as well.
± We±are±even±seeing±the±new±shackleless±provisions±on±MRAPs±being±
misused!±Once±again,±hooks±are±placed±into±the±smaller±bolt±holes±rather±
than±engaging±the±provision±directly.
± Finally,±blockage±is±sometimes±an±issue.±Even±with±shackleless±provisions±
