Select proper snap-in AND get instructions to size the glass

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

Hi there- thanks for reaching out! 

Could I have the dimensions of the finger latch? The rubber glass spline seems to match our 59-067 universal spline.

Hi. The dimensions of the finger latch are overall (both parts) 3.527. The longer latch part is 2.269. The height is 0.582. You can see it in the photo I sent before

Besides the snap-in issue, I hope you can address my question about how to measure the glass correctly.

Thank you.

I'm afraid I still cannot determine what latch you have. I've related a few different possible replacements to this page. You'll have to remove the original in order to determine which, if any, will work for you. 

On glass size, back when I did glass repairs for storm sashes, I would lay the glass on the sash cut and drop it right into the frame. You do want somewhat of a tight fit. 1/16" of play does sound correct. On a typical storm sash they don't give you too much of a lip for the glass to lay in. You should also use some type of adhesive on the frame to secure the glass. Talk to a hardware store or glass shop in your are to see what type they suggest.
