CRL 28" Window Sash Channel Balance 2720 (27-2) Replacement

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

Each CRL FA Series 2/20 Weight Range Sash Balances (example SKU: FA2720) pairs with nylon top and bottom guides that must be riveted to the channel. For easy installation, order channel balances with guides pre-attached at the factory, or choose guide kits with rivets included to install yourself. For the strongest rivet set, use CRL Cat. No. H3740 Rivet Set Tool, which mushrooms the rivet for a secure hold. These durable window channel balances are a reliable replacement for sash balances and OEM-style window hardware.

Special weight-range channel balances are available by special order. Stocked balances run FA1210 through FA4240; the 10, 20, 30, 40 and 50 indicate the counter-balance weight designation. If a channel balance shows 90 (or 9
