The latch bands come together at the bottom of the T/R. The right latch band has a latch band T-bolt receiver and the left latch band has the V-band latch assembly. The latch bands are attached to the thrust reverser with retainers.
The v-band latch has an adjustable hook to adjust the amount of force to close the latch. The v-band latch handle unfolds to open the latch or close and lock the latch. The handle folds to stow the latch handle.
Functional Description
The hook on the v-band latch engages the latch band T-bolt retainer. The latch handle draws the hook back and puts the tension on the latch bands which clamps the thrust reverser halves together on the engine fan case. The force on the latch handle to close the latch is approximately 55 pounds (245 newtons).
