Sliding Door Seal / Draft Problem

[Uncle Freddy]

hello and thanks in advance for the help / assist guys ....see video link with volume up for the problem we are having with our sliding doors to rear patio ....these doors are 5.5 years old, they were installed when we built our home in 2018

Doors are designed to have a bit of play along that interlock so that the door can grow or move along that line.

Have you checked to see if you get the door centered, i.e. right in the sweet spot, that it engages both interlocks and provides a relatively tight air seal along both sides?

If so...get a foot bolt for the non dominant active size so that it is locked in that position.
