A Spider-Man wannabe scaled to the top of the Midtown skyscraper that’s home to the upscale Four Seasons Restaurant on Thursday — then safely climbed back down, only to be arrested, police said.

The 23-year-old man was caught after climbing up the 11th floor of the 39-story Seagram Building at Park Avenue and East 52nd Street at about 5 p.m., cops said.

“He was in regular clothes, nothing special or crazy,” said the doorman of the Four Seasons. “He was shimmying up the building. He jumped over and went on the other side.”

“Some girl in our office space said, ‘Wow, someone is sliding down the black rod,’ and claimed a police officer was chasing after him on the platform,” said Cynthia Ross, who works on the eighth floor. Cops cuffed the daredevil two blocks from the building, at East 54th Street.

The climber was in custody Thursday night at the Midtown North Precinct station house and had yet to be charged, cops said.

He was not identified.
