Tightrope walker Nik Wallenda will wear a safety harness as required when he attempts to step across Niagara Falls on Friday, but he told CP24 he's afraid the device will be more of a hindrance than a help.

Wallenda's original plan was to walk across a cable suspended 60 metres above the falls without the harness, but the U.S. TV network airing the event, ABC, demanded he wear one during the stunt.

The daredevil said he "respects" the network's decision but he's "nervous" because he has never worn a harness before. 

"The safety harness will make it a unique experience," he said. "It's almost a hindrance -- I am excited but I'm nervous. I am more nervous about the safety harness than any other part of the walk."

So far, all other plans have fallen into place, he said. 

The cable will be strung across the falls tonight by helicopter, as originally planned. Last week there were concerns the helicopters wouldn't receive the appropriate permits on time.

Wallenda said a thicker cable had to be put up because there are no stabilizers in the area. The cable typically sways eight-to-10 inches.

Wallenda will attempt to traverse 550 metres, under the dark of night, in a stunt that has never before been attempted on live television.

His history-making tightrope walk over Niagara Falls between the U.S. and Canada will cost up to $1.3 million, according to The Associated Press.

Wallenda told the news outlet that a deal with ABC to televise the event live will offset some, but not all, of his expenses.

He is asking the public to help cover the costs by contributing to his fundraising goal.

As of Tuesday, a video on the fundraising website Indiegogo had raised more than $15,300 towards a $50,000 goal.

CTV will air the event live at 8 p.m. on Friday. Tune in to CP24 for extended coverage.
