Hello,
I replaced the stationary side of my sliding glass door last spring. It is a MW Classic door, who have since been purchased by Ply Gem, but they honored the glass warranty. I reused the original retainer strip, but I must have warped it un-installing and re-installing, so now it will flap-flap on windy days. I can't find retainer strip products online, but snap in glazing bead looks pretty close. I just can't find one that matches. Product 55-164 looks close, but is not exact. Any help you can offer would be appreciated. Thank you.
