Yes they are.
They also do not block ant mounting holes


darn ..That looks like a great Idea to minimize flex. I made my own cole jaws I hope they can be modified without have to do it all over,

There really is no measurable flex once the jaws are mounted. The design simply keeps the jaws aligned on the same plane.
The extensions I made fit with a tight tolerance fit, I wax the mating surfaces to keep them moving smoothly without play.

Instead of holes to mount the rubber, why not have a slot? Get the piece centered on the chuck using the tail stock and slide the rubber to the rim? Leave enough "meat" at the inner and outer circumference to give the jaw enough support (?)  Seems like Reed's warped pieces would be mounted a little easier.

Cole jaws are no different than standard metal jaws. For "standard" round pieces, slots are not necessary and actually more of a hassle.

Slots are good for asymmetric pieces but as mentioned above require the center point from the tailstock to initially center the piece before securing it via slots or other fastening method.

I personally don't use the tailstock when I'm trying to finish tooling the bottom of a piece, it just gets in the way and in most cases for me is not necessary.

Just be safe

I forgot to add that the Vicmarc jaws have both slots and screw holes.
There are endless configurations  that can be achieved

Oneway's Jumbo Jaws also have slots as well as screw holes.

Presumably the Nova buttons might fit on other jaws besides Nova's, if they use the same screw thread (or perhaps the screws could be swapped out as necessary?).

The "SOS Chuckies" from RubberChucky.com are another option for "buttons" on Cole jaws (or directly on the chuck, for that matter).
