Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Belts and belting rose 5.0% over the last 12 months, but all of its main inputs rose faster: synthetic rubber, including sbr and ethylene propylene +9.6%. That cost pressure may still pass through to prices.

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 — Rubber and Plastics Hose and Belting Manufacturing, Transmission Belts and Belting (BLS series PCU326220326220D2), published by BLS. Base Period: the index value published for September 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.]
A narrow, named cut of the rubber and plastics hose and belting series. Use it specifically for belt drives, not the parent series, when the contract is belt-specific.
Divide the current value of BLS series WPU07110224 (Synthetic Rubber) by its value at contract signing, then apply that ratio to the synthetic rubber part of the price. A usable clause also names an averaging window, a rule for revised values and missing months, and a cap.
Escalake tracks US PPI — Rubber and Plastics Hose and Belting Manufacturing, Transmission Belts and Belting, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
