Simplex T-Bar Lock Turn Direction

I was just going over the Simplex t-bar-type pull stations I have & noticed that, while most of them have locks that turn to the left, I have at least two that turn to the right: the former are all of the 4251-series t-bars & most of the 2099-series & 4099-series t-bars I have, while the latter are a 2099-9754 & a 4099-9001, both of which have the 1993-2010 Simplex logo (the other 2099-series & 4099-series t-bars I have have either the 1976-1993 logo or the 1993-2010 logo). Did Simplex change the direction their t-bars’ locks turn at some point? (or are the locks on some of my t-bars just upside-down, heh) I should also note that the other 2099-9754 I have has its lock turn to the left.

I actually never noticed nor did I know about this. Maybe it’s a generational thing, but us enthusiasts have never really payed any attention to such details, I don’t think so anyway.

I’m not sure I did either at first, but considering all but two of the t-bars I have turn to the left instead of the right, I thought I’d bring this “discrepancy” up with the rest of the community & see what they think/have to say about the matter.

When i saw the subject im like, well older and newer, but if you got them from a building, locks got changed to a newer lock??

Well, likely most of them came from buildings, but I wouldn’t know which did for sure. The difference in lock turn direction might be from a change Simplex did at one point however, which is what I’m trying to determine.

Well as I’ve said, I’m not certain that it’s actually because Simplex changed it: for all I know it could just be that the locks on some of my t-bars are upside-down, especially since most of them turn to the left instead.
