The template I ordered was useless. The pins were so small that it allowed about 1/4" of lateral movement, which means that the slack exceeded the working tolerance of the hinges.
I ordered the Hettich from Amazon.de, but they canceled the order. There seems to be some delivery issue from Germany to NY.
I just ordered the Hettich fixture from Ovis, which surprisingly has a larger shipping cost ($4.95) from Virginia than Amazon had from Germany.
However, this time I would expect that the delivery will actually occur.
