Collingwood president Eddie McGuire has fired up over Port Adelaide's request to wear their traditional 'prison bar' strip more frequently beyond 2020 and has even threatened to take them to court.

On Wednesday, Power president David Koch confirmed the club would wear their traditional SANFL black and white 'prison bar' jumper in Round 2 Showdown against Adelaide. Koch called the design the "people's guernsey" and a "significant moment" for the club.

But in a radio interview days before the official announcement, Koch said he will talk with the AFL about showcasing the strip more often.

"I think it should allow us to wear it in Showdowns, because Showndowns have such significant heritage value for South Australian football. That's what I will be discussing with the AFL when we talk about wearing it in the Showdown next year," Koch told 5AA.

When Koch's soundbite was played on Channel Nine's Footy Classified, McGuire was frustrated and called the whole jumper argument "so boring".

The Power's traditional strip shares the same colours and vertical stripes as Collingwood's. Koch's push for Port to wear the jumper more often in the past has ruffled some of Collingwood's and McGuire's feathers. Port Adelaide's SANFL side is also known as the Magpies.

Veteran AFL reporter Caroline Wilson said Koch and Power chief executive Keith Thomas would take the request further to league boss Gillon McLachlan and AFL Commission Chairman Richard Goyder and ask whether the club can wear jumper past 2020. However, the request would likely be to wear in South Australia and only in Showdowns.

But McGuire pointed out what Collingwood's response would be.

"Every single time Port Adelaide has asked for this for a special occasion we've said yes. Even when they played a final against Richmond, which really had no reason, but we said 'OK'," McGuire told Footy Classified.

"I don't want to buy into this because Port Adelaide is celebrating their 150th anniversary. They're a mighty club, we wish them all the best. So I don't want to go into this again and again because we have handshake agreements, we have contracts, we have trademark agreement, the AFL own the trademark.

'What annoys me, and I think David is being so disingenuous to his own supporters, is he goes on South Australian radio or TV and he fizzes them up.

"The Magpie is Collingwood Magpie - and that's that."

Wilson pointed out the Power's jumper only had the 'prison bars' and not the Magpie.

But McGuire said: "I'll tell you what, next time you go, have a look at their merchandise. It's got Magpie all over it, it's got black and white.

"There are major things when you have an identity and it's you trademark - and Collingwood's is the Magpie and the black and white.

"David doesn't have the guts to tell his supporters that it's finished.

"When they tried to run the Magpie out of town, we came in to support them. Now David, to his credit, has always been a strong supporter of the Magpie, [but] you're not - and you can't - wear it."

When asked if the AFL could approve the jumper request beyond 2020, McGuire said: "They can't. Well they can - if they want to go to court.

"If the AFL Commission doesn't do what it's there for -i.e. protect clubs and it trademarks - then they're going to really get into some [trouble].

"The bottom line is they're a great club - enjoy it. David, why bring this up the week before we're all going to get back? You've got a Showdown, it's you 150th birthday mate, relax. Any time you've ever asked on a special occasion, we've always said yes.

'If [the Commission allows Port to wear the jersey more often beyond this season], we'll get the bloke with the horse-haired wig to decide."
