CRL 23" Spiral Window Balance Replacement Non-Tilt Red Bushing

• For sash load weights up to 25 pounds
• Industry standard 3/8" (10 mm) tube diameter
• Replaces metal or plastic tubular spiral balances

This standard-duty CRL Tubular Spiral Non-Tilt Window Balance (SKU: FM2320) is a direct replacement for 3/8" (10 mm) tube spiral balances with a white nylon bushing, supporting sash loads up to 25 lb. Ideal for repairing single-hung and double-hung windows, it replaces either metal or plastic tube balances and matches industry-standard fittings. We recommend replacing both balances in a window at the same time for consistent performance.

How to order tubular spiral window balances

1. Check old balance tube diameter: 9/16" = Series "FJ"; 3/8" = Series "FM" or "FR" (depending on rod fitting).
2. Measure tube length only — do not include rod length.
3. Confirm nylon bushing color: White or Red = Standard Duty; Blue = Heavy Duty.
4. Verify the rod fitting that protrudes from the nylon bushing. Choose "FM" or "FR" if diameter is 3/8".
5. Order the required quantity by catalog number (SKU FM2320 for this item).

Key differentiators: SKU FM2320 — standard-duty 3/8" tubular spiral non-tilt balance, white nylon bushing compatibility, direct replacement for metal or plastic tube balances. Order now to restore smooth, balanced operation to your windows.
