Thanks for pointing me to this strap. I have been using a Camera Slingers "Dual Deluxe" and although I have been happy with wearing it I have been unhappy with the support. I lost one of the connectors and have not been able to get a replacement I have contacted them and was told yes we have them but no further response when I say I want to order one.
So I will be a new owner of
RS DR-1 Double Strap

I saved a few $ and bought an Optech Dual Harness......I have no qualms about it at all really......I had to really shorten the camera straps and have them velcroed so I did not have to cut them......all in all they work and keeps the weight off my neck......just what it is supposed to do.

I can hang my D300+50-500 on it alone with no problems.......the 50-500 on a neck strap really made my neck hurt....this replaces my Crooked Horn Outfitters Bino Rig I was using........and my Smuggy straps............

I thought the price was a little steep for the straps but I now have the single and double straps. Would never go back to a standard shoulder strap!. I photograph lots of motorcycle and automotive events and to have a wide angle and a long lens ready at all times is worth every penny! This allows me to carry two cameras and have my hands free at all times and not having the bother of lugging around a bag too. I've had tons of photographers come up to me and ask about the straps and say they're placing their order the next day!

I had heard of reports of the cameras separating but nobody would confirm if it was the screw coming undone or the clip weld failing at the swivel joint. (Hope I described that correctly). Anyway, here is my safety system and also how I fasten to a RRS L Bracket. The scuff on the camera body is from originally not sliding the L Bracket over just a smidge to have room to disconnect the clamp. Oh well, minor battle damage on a well used camera.

Just an update since this thread was resurrected. I've had my original BR strap now for a few years. It's the original strap with the original connectors. I have yet to have any problems with it. It has never broken or come loose from the camera. Completely happy with the strap. BUT...

On a recent trip to the beach. I had the strap removed entirely from my camera and stowed in a mesh pocket on my backpack. The little star-shaped ring (pictured) worked it's way loose and fell off. I lost it. Really bummed about it. I just ordered the new Fasten-R3 to replace it and hope it works as well as the original.

Love my Black Rapid. Totally earned its keep during my week walking the streets of Kyoto.
