Frampton's move to Adelaide from Port Adelaide was rubber-stamped on Tuesday afternoon for a future fourth-round selection.
The pick originally came from Melbourne, made its way to Hawthorn in last week's Sam Frost deal, then was used in the Jon Patton and Sam Jacobs trades before the Frampton swap.
AFL.com.au flagged the Crows' interest in Frampton in September, with the 22-year-old keen to emerge from the shadows of a series of other talls at the Power.

Jacobs' departure to Greater Western Sydney opens a spot for Frampton, but his best career form has so far been in attack.
Frampton inked a two-year deal with Adelaide, with conditions in place that could trigger a third season.
His agent, Andrew McDougall, of Corporate Sports Australia, told AFL.com.au that Frampton was "really excited" about joining the Crows.
"(Adelaide's) Justin Reid and (Port Adelaide's) Jason Cripps worked through it really amicably and professionally, and they got the deal done today, which is fantastic for Bill," McDougall said.
"It's given him a fresh start and opportunity to play AFL for the Crows, and it's a great time to go to Adelaide, with the younger group they're going for and some changes they're making there.
"He's an Adelaide boy and actually grew up supporting the Crows. He learned a lot at Port and was grateful for the opportunity with them as well.
"He's played only a few games at AFL level, but he's shown he can really clunk a mark."

"We have been watching Billy for awhile now and we believe he can have a real impact with us over the years to come," Crows general manager of list management and strategy Justin Reid said.
"Billy is one of a number of young players we are bringing in to rejuvenate the list as the club moves forward.
"Whether it’s up forward or helping out in the ruck, Billy will add some real competitiveness to the team."
