Each CRL FA Series 3/30 Weight Range Sash Balances is a replacement window channel balance that requires nylon top and bottom guides to be riveted onto the metal channel. For a durable rivet set, customers can use CRL Cat. No. H3740 Rivet Set Tool (sold separately), which mushrooms the rivet for a strong mechanical set. These balances are ideal for window channel balance replacement and sash weight compensation in residential and commercial double-hung windows.
