double roller for Simonton patio sliding door

Hello,

Your roller resembles the 81-158 depending on how the housing height compares to yours. The wheel is smaller than ours but the adjustment screw in the back of the assembly will allow you to adjust the wheels to make up a difference in wheel diameter within + or - 1/2", so if that's the only difference, the 81-158 should work for you. Keep in mind that the overall length of the housing is not as important. Let me know if you have any further questions.
