window sash removal

Unfortunately you have Alenco's builder's grade windows. They are non tilt and designed specifically so that you cannot remove the sashes. You will need to work on them with the sash in place. It's hard, but it's not impossible. You will need to have someone hold the sash up for you while you disconnect the balance from the bottom of the sash, then close the sash and carefully work the balance out from the top.

Once it's out, please tell me the diameter and length of the tube. I'd also like to see how it attaches to the sash at the bottom. Finally, I'd need to know the weight of the sash. Due to the nature of the window, you won't be able to get an exact weight, but if you put a scale on the sill and gently lower the sash you should get a good idea.

The plastic strip you need could match up with our 55-189 glazing bead. Check out our dimensions to see if they line up.

Unfortunately, you won't be able to remove the sash. You will need to replace the vinyl snap in, 55-189 with the sash in place. Their is no modification you can do on the window without damaging it. You may want the help of a local professional.
