Do NOT use it as a ship stair, service stair, equipment hatch, smoke vent, or custom-size curb replacement without verifying the opening and submittal drawings.\u003c\/p\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003ch4\u003eWhat opening size does the S-20 fit?\u003c\/h4\u003e\n\u003cp\u003eThe Type S-20 hatch is specified for a 36 in x 30 in curb-to-curb opening. Confirm both the rough opening and the hinge-side orientation against the project drawings before ordering.\u003c\/p\u003e\n\u003ch4\u003eIs it easy to open from a ladder?\u003c\/h4\u003e\n\u003cp\u003eYes. Bilco Type S hatches use a counterbalanced cover and automatic hold-open arm so the user can open or close the cover while keeping one hand on the ladder.\u003c\/p\u003e\n\u003ch4\u003eIs the hatch insulated and gasketed?\u003c\/h4\u003e\n\u003cp\u003eYes. The Type S guide specification describes an insulated cover and curb with gasketed, overlapping cover construction for weather resistance.\u003c\/p\u003e\n\u003ch4\u003eCan it be used in high-wind coastal work?\u003c\/h4\u003e\n\u003cp\u003eBilco literature and distributor technical pages reference Miami-Dade and Florida approvals for the S-20 family. Verify the exact approval document and project wind requirements before submittal.\u003c\/p\u003e\n\u003ch4\u003eWhat roofing detail matters most?\u003c\/h4\u003e\n\u003cp\u003eThe curb\/flashing interface matters. Coordinate the Bil-Clip or project flashing detail with the roofing membrane so water is directed away from the curb and the hatch warranty is not compromised.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eRoof hatches are fall-exposure access points. Coordinate guardrails, ladders, lockout\/security, and local code requirements with the project safety plan.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eProduct Expert Notes\u003c\/h3\u003e\n\u003cp\u003eA good pro-grade hatch listing because buyers need exact opening, access style, curb\/flashing details, and approval confidence more than lifestyle copy. The S-20 should be sold against drawings, not guessed from a photo.\u003c\/p\u003e","brand":"Bilco","offers":[{"title":"Default Title","offer_id":53103230583151,"sku":"BILS20","price":1020.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/ProductImage_BILS20.jpg?v=1781162660","url":"https:\/\/superarbor.io\/products\/bilco-s-20-galvanized-type-s-roof-hatch-36-in-x-30-in","provider":"Super Arbor","version":"1.0","type":"link"}
