See our S395-26. I believe this is the channel balance you need. For a new stamp option, choose 2540. For the 30" balances, if they are also the Series 395 (i.e. the nylon fittings are the same), to know what stamp option to select you'll have to obtain the exact weight of the window sash that uses the balances. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the shop page. All our balances come fully assembled and ready to install out of the box. |
