Stamp Option and Top Sash Guide Identification

Question

Hello,

I need help identifying the sash weight range on this balance. I have a house where I am replacing the balances in 8 windows. 7 window sashes are 34" and 1 is 46". All of the use te same type of 29" balance and I believe it is the series 380. See photos. There is only most of the balances have no marking and a couple have 28C on them. See photos.

The top sash guide is black with a 1" wide top and is 1-3/4" long for a 1/2" track. See photos. A replacement doesn't need to be black, but I could locate a replacement on your site.

I have more photos, but can only upload five.

Thanks for you help,

Richard

Thanks for posting, Richard. If your old stamp reads "28C" then you can probably use our 2830 option, but you should probably weigh your sash on a scale to be 100% sure. That's the only real way to confirm. We have a chart on the S380-29 store page that tells you exactly how much weight each option supports.

For the top sash guide, see our 18-180.
