Upon further investigating, it appears the brittle plastic piece that is screwed into the window frame is the cause of the springs inability to stay down. The two photos submitted shows the issue....do you have these parts available for all of my windows?
I ordered 42 if them from you on Tuesday. That was the correct part. Could you confirm the proper channel guides if needed? Is it series 385?
Appreciate all the guidance you have provided. After studying and reviewing the current channel guides I have another question. It appears the only difference between the S385 and S380 is one dimension in depth on the attached shoe. The S385 is 1 & 3/32" while the S380 is 1.0". Am I missing any other differences? Thanks again!!
Nope, that's the only difference. All you have to do is measure your shoe to determine which is better. Also, make sure to keep wear in mind when you measure; to be more specific, due to friction over the years, your shoe might be a little smaller than it was originally.
