Trust you mean the Petzl one - from my days in oil and gas process work - Note To Manufacturers: Wherever possible make any wear items commonly available - it took me a while to find the Petzl bridges initially when I had to replace mine so I ended up buying a couple as capital spares. But who knows down the road? That's a feeling I don't like. What I do like is service manuals that say our bearing replacement is part number so and so, but if you can't get that in time, use this or this or this from other bearing suppliers. That kinda stuff shows committment to customers to keep stuff up and running in the field (sans chicken wire and duct tape solutions). Maybe those days are long gone however.
