{"product_id":"4-09-shingle-gauge","title":"4\/09 Shingle Gauge","description":"The 4\/09 Shingle Gauge™ measures the thickness of a shingle, and based on analyses made by Haag, correlates that thickness to a warranty level. Knowing a warranty level can be important in determining what a comparable replacement shingle might be. While the Shingle Gauge™ was designed with the strictest analytical tolerances possible, we still consider it an estimating tool due to a small number of shingles which do not conform to the gauge. Haag created the 4\/09 Shingle Gauge™ by testing asphalt-based composition shingles. Modified asphalt shingles (commonly called \"impact resistant\") were not included in our testing and are not applicable to the 4\/09 Shingle Gauge™.","brand":"PRS Tools","offers":[{"title":"Default Title","offer_id":47597986578729,"sku":"409","price":22.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/8114\/6153\/files\/I000005-4-09.1.png?v=1706862553","url":"https:\/\/prstools.com\/products\/4-09-shingle-gauge","provider":"PRS Tools","version":"1.0","type":"link"}
