Verify pipe count and grouping at each location before ordering, since grouping several small conduits often calls for the next size up. Always detail the curb into the membrane field, not on top of an existing patch.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eFollow the manufacturer's installation instructions and local roofing codes when sealing penetrations, and use appropriate fall protection while working on the roof.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eOrder the Chem Link E-Curb Rectangle today for a clean, molded seal at your roof penetrations.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Chem Link","offers":[{"title":"Default Title","offer_id":53524667203951,"sku":"CHEECR4535GR","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/webimage-IMG-E-Curb-Penetration-Seal-Components-CHEM-LINK-inch-Ecurb_0946a0e7-236b-492e-a3e2-5cad20530efc.png?v=1790285055","url":"https:\/\/superarbor.io\/products\/chem-link-e-curb-rectangle-4-5-in-x-3-5-in-gray-penetration-seal-curb","provider":"Super Arbor","version":"1.0","type":"link"}
