You will find lots at your local gliding club! They are spoilers that typically project above/below the wing. They destroy a variable amount of lift and at the same time add some drag to steepen the approach without increasing speed. In a perfect langing you make your final turn, pop the spoilers out to 50% and they stay like that all the way down to the ground. That way you have the max amount of throw available in both directions.
