Each CRL
FA Series 4/40 and 5/50 weight range sash balances (SKU FA3240) requires nylon top and bottom guides to be riveted onto the channel. Order channel balances with guides pre-attached, or choose guide kits with rivets to install yourself. For faster, stronger installations, use CRL Cat. No. H3740 Rivet Set Tool — it mushrooms the rivet for a durable set. These features make CRL FA Series channel balances a reliable choice for window repair and sash balance replacement projects.
Ordering Tips for FA Series sash balances Remove the existing channel balance from the window and measure the metal channel only — do not include the guides. Measure to the nearest full inch.
NOTE: A few manufacturers used special 1/2" (12.7 mm) increment channel lengths; these are not stocked but can be special ordered.
Always check the stamped or laser-etched number on the back of the channel balance — it will be four digits or two digits plus a dash and digit (for example: 2710 or 27-1). Use that stamped number to match the CRL catalog number. For example, a full 18" (457 mm) channel stamped 1710 or 17-1 corresponds to CRL Cat. No. FA1710; a full 27" channel stamped 2610 or 26-1 corresponds to FA2610. The chart lists vent weight ranges indicating the sash weight a pair of channel balances will hold (does not account for excessive weatherstrip friction).
NOTE: Use the weight range chart for reference if the stamped number is unreadable.
Special weight-range channel balances are available by special order. Standard stocked catalog ranges include FA1210 through FA4240, where the 10, 20, 30, 40 and 50 indicate the counter-balance weight designation. If your balance shows a "90" or "9" (for example 2790-26) or a "DS" suffix (for example 27DS-34), the part was manufactured to carry a specific sash weight (e.g., 26 or 34 lb per pair) and may be designed for upper or lower sashes only — provide this information when ordering.
Product Warning:The first two numbers of the CRL catalog number do not represent the channel length.
