I bought this assuming it was an RJ-11 / RJ-12 6P6C connector.  This has an RJ-45 8C on both ends.  Is the exact same footprint as the 8 wire fluke model, except it only has 6 copper contacts to connect your but set to.  The just remove 2 contacts from this 6 wire model.  I returned and upgraded to the 8 wire model.  Just seems silly or a waste to have a 6 copper contact for an RJ-45 jack.  I would have been happy with this one, if it came with an RJ-45 8C to RJ-12 6C K plug.  But it comes with RJ45 K plug on both ends.  Hope this helps someone.
