USnavy,
You're forgetting 2 things in your analysis.
#1 - The Quick Release was spec'd by Special Forces, not us. Remember, the fast rope insertion technique was developed for getting into hot combat zones in a hurry. Fractions of seconds count. Fumbling around with a double action locker while being shot at is a bloody waste of time.
Not sure if it was intended (didn't think you to be a brit, Mal)....but jumped out at me as a rather (in)appropriate pun. Laugh

I meant that in the literal form, not the British adjective form. It's usually bloody if you get shot or blown up.

#2 - The guys fast rope in with big heavy gloves and it's almost impossible to operate a regular carabiner, let alone a double action twist lock, with gloves on. Try this: take our favorite locking carabiner down to a welder's supply store. Put on a pair of the welder's gloves and try to open that locker. Got it? Good. Now go stand in a hot combat zone with a mob trying to shoot you and sending RPG's your way and try it Oh...And don't forget all the swirling dust from the rotor wash.

BTW, the QR spec was determined by SOCOM and handed to us. They have needs that are so far beyond what we civilians can even imagine that I don't even try to argue.
Alright, fair enough. So how do multiple people get down the same line? Do they stack a bunch of those big ass rap devices in a line at the top and everyone clips into one when its their turn?

USnavy,
The FRD is not designed as a "rappel" device for individuals. It is designed to help combat personnel fast rope dow with a load that exceeds their personal 100lb load. When a squad or platoon goes in they'll often have crew-serve weapons, medical kits, canine units or non-fast rope certified personnel like interpreters. They have even been using them to descend with light 2-cycle dirt bikes. Without a FRD, the helo would have to return after the area is secured and either land or winch down the extra load. The FRD allows the unit to insert everything in a single pass, without landing or winching. Here's the sequence.

Before the helo takes off, the standing end of the fast rope, usually in a Yates haul bag--think giant throw-bag--is secured to the overhead FRIEs bar, the FRD is attached to the fast rope at the FRIEs bar at the very top and held up with either another QR leash or a break-away cord. The attached FRD does not affect the standard use of the fast rope. When the helo arrives on site, the fast rope bag is kicked out of the helo and the initial combat personnel slide down it, sans FRD, as if it were a fireman's pole. Then the soldier with the extra load clips the middle of the QR leash to the FRD, loads it and descends to the ground under control, release themselves from the leash with the QR and run for cover. Depending on the situation, the helo crew can either cut away the entire rig at the FRIEs bar, leaving it as battlefield debris, o they can haul it in for re-use.

One of the local shops gets the exact same stuff (Amsteel grey) for less than 1/4rd that price.

I have to ask. What is " 1/4rd "?
It's a little bit smaller than 1/3th.
