CRL 27" Window Channel Balance Replacement 2640/26-4

• Measures 5/8" (16 mm) channel depth — commonly referred to as 1/2" (13 mm) in the trade
• Available in 10, 20, 30, 40 and 50 weight-range balances in lengths from 13" to 43" (330 mm to 1.09 m)

Each CRL FA Series 4/40 and 5/50 weight range sash balances is a heavy-duty window channel balance designed for reliable counterbalancing of single- and double-hung sashes. These channel balances require nylon top and bottom guides to be riveted onto the channel. Customers can order balances with guides factory-attached or purchase guide kits (rivets included) to install guides in the field. For secure installation, CRL offers the Cat. No. H3740 Rivet Set Tool, which properly mushrooms rivets for a strong set.

Ordering Tips for FA Series sash balances

Remove the existing channel balance from the window and measure the metal channel only — do not include guides. Record the measurement in full-inch increments. Always check the stamped or laser-etched code on the back of the channel balance (either four digits or two digits plus a dash and a number, e.g., 2710 or 27-1) and use that code to match the CRL catalog number (for example, a stamped 1710 or 17-1 on an 18" channel corresponds to CRL Cat. No. FA1710).

Note: Some manufacturers have used special 1/2" (12.7 mm) increment channel lengths—these are not normally stocked but can be special ordered.

If the stamped code is unreadable, use the weight-range chart for reference. The listed 10, 20, 30, 40 and 50 designations indicate the counter-balance weight range a pair of channel balances will support; this does not account for extra friction from heavy weatherstripping. Special-order balances are available for nonstandard weight designations (for example parts stamped with 90 or 9, or codes with “DS” indicating a specially calibrated sash weight). Provide any special sash application (upper or lower sash) when ordering.

Product Warning:

The first two numbers of the CRL catalog number do not represent the channel length.
