Delivered by Grappling an Extremity

Delivered by Grappling an Extremity is a +0% specification of Follow-Up on GURPS Fantasy pg 205, bottom of right column under Dismemberment
This appears to be a variation of B105:
:If the carrier attack is a natural weapon, such as Claws or Teeth, Follow-Up is a +0% enhancement.
The top of the left column of pg 206 elaborates on how it works. Isolating how it works alone is complicated by how it interacts with All or Nothing.
It doesn't do immediate damage, but instead adds a damage bonus to Arm Lock or similar. The extra damage is lost if the following steps happen:
#HT roll by target is generated by total being high enough to cripple
#target succeeds in HT roll
Strangely, if the total damage isn't high enough to roll to try and cripple the limb, the bonus damage doesn't appear to be lost.
This is different from the Requires Grapple limitation because there is no 1 second waiting time.
