Drawing opening traps

Hello dear chess lovers,

I'm looking for lines in the opening that lead to a draw. This kind of trap isn't as popular as material gaining or even quick mating traps, but they can come in handy when playing a much higher rated opponent to which when getting a draw, one should be already content. So I'm not looking for names of drawish openings like the French exchange variation for white or the Russian opening for black often can be, but merely for specific lines. Like for exemple the following one in the queen's pawn opening.

hey very nice, i know one for white in the london system just reversed of the baltic defense Black captures Pawn on b2 Rb1,Ra1 follows greetz

Looks like that's the only know drawing weapon. Outside of the hammpee meitner game.
