Hello,
I like to put new glass into some old aluminum SEAL-RIGHT storms.
The picture "Storm 1" shows a cross section of the old snap-in, where the
associated dimensions are in drawing "Storm Seal-Rite 6...".
As for measuring up the glass, I watch the video which instructed to measure the length between the insides through which the glass passes, see black arrow on the remaining picture, and subtract 1/16". However, it was not clear if the 1/16 had to be subtracted from both sides (so 1/8 total) or just from one.
Thank You, Jacques
