Milgard Window Balances
Hi there- thanks for posting!
I was able to narrow what you have down to two options. You either have our Series 380 or our Series 385 channel balance. The difference lies in the depth of the shoe. The series 385 balance has a 15-004 shoe, which is 1-3/32" deep while the series 380 balance has a 15-005 shoe, which is 1" deep.
To determine the length of your balance only measure the length of metal channel. Do not include the end attachments in your measurement.
Carefully measure your balance as I explained above, and get back to us if you have any questions!
Thank you.
Hmm it's a little uncommon for a balance to end on a 1/8''. Does the metal channel have a stamp on it? If so, what does it say?
length of metal channel = 24 inches
Checked for part numbers/stamps on the metal channel and there are no markings.
Thank you.
Okay, great!
Now could you measure the depth of the shoe and let us know what that measurement comes out to be? We will also need to know the weight of your sash. This will help us determine which option you will select at checkout. You will need to remove the sash from the window and weight it on a scale. Typically the stamp would indicate this, but since you don't have that on your balance, the weight of the sash will tell us what we need to know!
Get back to us with that information and after that we should have narrowed it down to exactly what you will need.
If your sash is heavier than 27 pounds, then I don't think that will work for you. I would advise against going with that option. If your sash is exactly 30 pounds we can specially make a balance that can support that weight.
Can you confirm the exact weight of your sash, down to the ounce? Can you also tell me what the stamp read on your old balance?
