All,
Did some further research and providing more information from what I can glean from the catalogs and the website to see if they have further information about the questions that I have (Open/Box/Combination have Grip/Drive).
The catalog downloaded last week (so guessing it is still the newest) says:
WrightGrip:
Page 55 under heading of "WrightGrip Is Now Standard Feature" = "...on all open end of combination wrenches upto 1-1/4""
Kit #714 & 715 (pg 57) says WrightGrip, but only goes to 1-1/4"
Kit #726 (pg 58) says WrightGrip and implies that this feature is included in all wrenches upto the included 2", however the 730 set does not say WrightGrip. So, uncertain if you would even get the WrightGrip wrenches upto the implied 2" from the 726 set.
Bottom half of both Page 76 & 77 state that individual wrenches only have WrightGrip up to 1-1/4"
WrightDrive:
Page 55 under heading of ""More Bite from Wright" (last paragraph) implies that all Box End Wrenches have this feature. Outside of Sockets... I can't find any other mention of this feature for wrenches.
--If this statement is true (all box wrenches), than this should answer my question for the "Boxed Wrenches".
--Additionally implies that this is a feature on all there wrenches, no matter the size.
The Website:
http://www.wrighttool.com/online_catalog.asp
--Select "Wrenches"
--Select "Combination Wrenches"
Select any of the sub folders and on the right side under "Click here to view PDF Catalog" it says they all feature the "WrightDrive".
Select any of the sub folders and than select any of the individual wrenches, Details, a "pop-up" shows and select "Next Photo" (may have to increase the screen size to see, next the picture of the wrench) and can see which have WrightGrip:
--Can't quite see if any of the "Black" finish ones have it. To dark.
--Industrial and HD do not appear to have this feature.
--WrightGrip is only shown up to the 1-1/4" wrench.
NOTE: Humorously you would think the manufacturer would have enough wrenches on hand to show the correct size wrench vice a "9/16 WrightGrip". Also some of the pictures are so small that they are useless to view.
As stated before... I am finding that on ebay I can find larger wrenches with the WrightGrip, but sad that the Wright Website cannot be updated, nor that their customer service can answer my emails.
