Tomas Berdych and Radek Stepanek led defending champions Czech Republic to a third Davis Cup final in five years after easing past Argentina's Carlos Berlocq and Horacio Zeballos in Saturday's doubles.
Stepanek and Berdych won 6-3 6-4 6-2 in two hours and three minutes to earn an unassailable 3-0 lead after they had dominated Friday's singles.
The Czechs, who won the 2012 trophy by beating Spain 3-2 in Prague, will travel to Serbia for the November 15-17 final after Novak Djokovic and Janko Tipsarevic claimed straight-sets singles wins against Canada on the final day.
"We would like to keep the trophy because it's beautiful," said Stepanek.
The Czech duo won the 13th of their 14 Davis Cup doubles rubbers together since teaming up in 2007, while Berlocq and Zeballos played their debut doubles match together.
Pushed on by an emotional crowd of more than 11,000 fans around the superfast hardcourt at Prague's O2 Arena, the Czechs benefited from good serving and Stepanek's dominance at the net.
All they needed was four breaks, one apiece in the first two sets and two in the third.
"We played a great game. Everything was in the right place today, we didn't drop a serve," said Berdych.
"As long as you are able to make pressure on them, you make chances, and that's what we've done today," he added.
Serbia booked a final date with the Czechs later on Sunday after singles wins for world number one Djokovic and Janko Tipsarevic saw off the challenge of Canada 3-2.
Tipsarevic beat Vasek Pospisil 7-6 (7/3) 6-2 7-6 (8/6) in the winner-takes-all final rubber after Djokovic had seen off Milos Raonic 7-6 (7/1) 6-2 6-2 to tie the series at 2-2.
Tipsarevic was mobbed by the rest of the Serbia squad after his victory and in a courtside interview he said: "This is one of the sweetest wins of my career and I hereby wish to thank my team mates for their support.
"See you right here in the final against the Czechs."
