Coil Balance Selection by Pocket Depth and Series

Coil balances replace worn or broken factory units in retrofit and new construction workflows. Proper selection requires matching pocket depth, coil length, weight rating, and series designation to original equipment. Undersized or oversized units compromise sash operation and create binding or drop-sash failures.

Match Pocket Depth and Coil Configuration

Identify whether your frame accepts 1/2" or 3/4" pocket balances. Coil length (short, medium, long) must align with sash travel. Single, double, or triple coil configurations load differently—verify original unit or frame specs before ordering replacement. Wrong pocket depth creates installation gaps.

Weight Rating and Sash Travel Compatibility

Coil balances ship in 8 weight increments per length class. Heavier coils suit taller or weighted sashes; lighter ratings work for standard double-hung units. Measure glass height and frame depth to confirm correct weight band. Mismatched weight causes slow sash action or premature coil fatigue.
