What this means for your clause
A finished-product index for window and door units, useful in a building envelope contract where glazing and framing are priced as installed assemblies, not raw glass and metal.
Draft a clause
A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Metal Window and Door Manufacturing (BLS series PCU332321332321), published by BLS.
Base Period: the index value published for August 2026 (or the month of contract signing, if different) is the Base Value.
Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value.
Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement.
[Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
Compare the current value of BLS series WPU1311 (Flat Glass) to its value at contract signing, turn that into a ratio, and apply the ratio to the flat glass-affected line items. A usable clause also names an averaging window, a publication-lag rule, and a cap.
