美剧越狱第一季第二集中纸条上的schweitler allen是什么意思

美剧《越狱》第一季第二集中纸条上的“schweitler allen”可能指的是MS牢房里洗手池的商标名称“SCHWEITZER”，因为这个商标名称在剧中出现过。至于“ALLEN”即ALL，可能只是纸条上另外的文字信息，和“SCHWEITZER”并无直接联系。

这个可能是那个螺栓的制造商的名称。

He had a catalog with that name on it. The specific significance of the bolt will presumablybe revealed when we learn more about his escape plan.

One of the tattoos was used to judge the correct diameter.

Now, why THAT particular bolt is a mystery.
Presumably the bench was assembled with numerous similar bolts.
