Spiral Balance Rod Selection by Diameter and Tilt Type

Spiral balances are load-bearing components that control sash travel and prevent drift. Proper identification requires measuring rod diameter (3/8" or 5/8"), confirming tilt mechanism presence, and verifying attachment method (clip, crosspin, or shoe). Mismatched replacements cause binding, hard operation, or sash drop—common callbacks on retrofit jobs.

Identify Your Spiral Balance Rod Size and Configuration

Measure the rod diameter and inspect the sash for tilt function. 3/8" rods fit narrower frame channels; 5/8" accommodates deeper cavities. Tilt balances include a locking mechanism for tilted operation; non-tilt models provide constant support. Verify attachment hardware—metal clip, crosspin, or plastic shoe—before ordering to avoid incompatible fits.

Match Specifications: Diameter, Length, and Tilt Mechanism

Spiral balance length varies by window opening; measure from attachment point to end cap. Tilt vs. non-tilt designation determines sash tilting capability and internal spring tension. White finishes suit exposed installations; bare metal suits concealed frame cavities. Double-pin 5/8" models offer enhanced load capacity for heavier sash weights.
