Talk:Keystone module

History of term and specs
The term keystone as described here does not appear to have any origins.

It also appears to be a term adopted in the US for a particular type of connector shape or size.

I can find no information about the jack size or shape anywhere.

Rather than being a descriptive word i would suggest that this is a makers named item.

Certainly not at all recognised in Europe. And the information herewith is minimal. --81.137.234.49 17 September 2007


 * I've tried to provide more information as well as photos. I don't know if this is US specific, but keystones do appear to be widely available across the Internet from many different suppliers and manufacturers, and the term "keystone" is almost universally used by everybody for this format.  I also can not find any reference to the history or an official specification.  However I have run across a few different spec summaries which may provide some information.  It appears as if the front rectangular face is 14.5mm wide by 16.0mm tall.  The catch plane of the tabs which hold it in place (on the top and bottom) are offset 8.0mm back from the front face of the keystone and are 19.2mm apart vertically (the extra 3.2mm allowing for compression of the tabs during insertion). - Dmeranda (talk) 21:39, 21 May 2009 (UTC)

While they're sometimes referred (incorrectly) to as "keystones", can I recommend mentioning Panduit Mini-Com, and Commscope Systimax, and Commscope Uniprise as being similar, but three types of other proprietary modules? It's why I came to this page to figure out, and they're not even mentioned. There doesn't appear to be anywhere on the Internet that even compares or contemplates these, and for the likely audience of this page - this would be very important/helpful to be captured here. 205.233.58.249 (talk) 17:35, 23 February 2022 (UTC) Myke
