The Beast is 38mm outer diameter, and 28mm wide. The large Notch is 99mm x 49mm.
Huh... I always thought the X rings measured the same way the Antal ones did.. as in 38x28 meant 38mm donut hole, 28mm outter channel & the overall edge to edge sizes just aren't posted, unless you go off Antal's posted specs. Antal also doesn't have a 38x28 so the largest you can completely spec out is 28x20.
I also always thought the Notch rings were just a tad wider than the X rings, but what your listing is a difference in measurable inches..
Here's something below i made up a while back when trying to break down what's what..
Which lead me to believe this is how the sizes matched up..
Notch #3 = X Rig Beast
Notch #2 = X Rig Large
Notch #1 = x Rig Medium
Then there's the Seldon's, Harken's, WindDesign's, Ronstans & Tylaska's which sometimes don't follow the same sizing/numbering patterns & makes figuring out actual differences a bit difficult/ cloudy.
For example, i think that Seldon measurement of 70 is referencing the actual overall width of the whole thing, edge to edge & the 30 references the center hole, with no Channel size being used.
Which would land it somewhere around a Large 28/20 X Rig Ring.. I don't know the overall edge to edge on the XRig Rings off the top of my head, but I've always used Antal's charts as I've been under the impression theyre tic for tac in rope sizing.
If you look at the photoshop below you'll see where I'm getting the Notch /X Rig sizing comparison.
I will say i wish Notch & X Rig had a few more sizes in between both theyre largest options & they're second to largest options. However, albeit, they may not be as rugged, Tylaska seems to offer a quite a few to fill that gap.
