The LD450/470 models use a completely different combination chamber. On an LD450/470, for example, you can press the combination in any order. In other words, 4-5-3-2 is the same as 3-4-2-5. The combination chamber works off of switches oriented in the On or Off position. This isn't the case with the rest of the mechanical lock line that Kaba Ilco uses.
Sure, what sort of proof would you like?
Any sort of proof that your company is involved with this class action lawsuit and Kaba Ilco. Sorry if this is vague but realize that I don't want to be telling everyone that asks about this flaw - my apartment's pool is guarded by an L1000, for Heaven's sake!
Haha, all kidding aside, just need some sort of way to identify who you say you are for peace of mind, please. Feel free to PM me so we don't litter this thread with our correspondence. If you are who you say you are, I'll be more than happy to assist you as much as possible and then recommend others involved with this. I found out about the flaw when the lawsuit was filed but I know myself and many others have replicated the lawsuit's claims. I've done so both on my work bench and in the field and I'd be delighted to help both sides if it means a better product and solution, if only for my companies' customers.
