Take a look at our S395-30. This looks similar, but please compare to confirm. You'll then have to choose a stamp option. Your old stamp of 29-9 is from an outdated rating system. To know what stamp to choose, weigh your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the shop page. |
