I puchased one of their locks about 6 months ago and just recently attempted to use it for the first time, only to find it was the wrong size. Having lost my receipt I could not verify if I had ordered the wrong lock or if the mistake was at their end. I contacted Altor, explained the situation, and asked what could be done. The rep responded that they had my original order on file, that I had ordered the correct lock, that the mistake was at their end, and they were shipping me a new lock free of charge. I find honesty and integrity to be increasingly rare commodities these days, but this company has both in spades! Thank you Altor (Thank you T.J.). Also, the locks themselves are well engineered, well made, and vastly superior to anything else that I am aware of. Thanks again.
