Fabricated from hot dip galvanized steel at 16 gauge, this frame provides a rigid, corrosion-resistant border at the wall or ceiling opening where a boot meets the finish surface. It holds the rough opening in place during plastering or drywall finishing, keeping the duct register opening clean, square, and flush. HVAC sheet metal installers and mechanical contractors use this component during new construction and renovation work where a professional, finished duct termination is required.\u003c\/p\u003e\n\u003cp\u003eThis plaster frame is suited for return air applications in forced-air systems where the boot penetrates a plaster or drywall surface. The 4 inch by 10 inch frame size matches standard boot and register dimensions common in residential duct layouts. It is installed before finish work is applied to the wall or ceiling, allowing the surface material to be worked up to the frame edge. The galvanized construction holds up in unconditioned spaces and during the construction phase before the system is commissioned.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in typical HVAC rough-in environments\u003c\/li\u003e\n  \u003cli\u003e16 gauge material thickness provides rigid support to hold the rough opening square during finish work\u003c\/li\u003e\n  \u003cli\u003e4 inch by 10 inch frame size matches standard return air boot and register dimensions\u003c\/li\u003e\n  \u003cli\u003eDesigned for return air duct terminations in plaster and drywall applications\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct fabrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal component for return air duct plaster frame applications in residential and light commercial forced-air HVAC systems using standard 4 inch by 10 inch boot and register openings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed sheet metal workers or HVAC mechanical contractors following SMACNA duct construction standards. The frame should be set and secured at the duct opening before plastering or drywall finishing begins. Verify the opening is plumb and square before fastening. Shut down any operating HVAC equipment before working on duct terminations in an active system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrame Size\u003c\/strong\u003e: 4 inches x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Thickness\u003c\/strong\u003e: 16 Gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Return Air\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31PF-16GA_4X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283907674418,"sku":"31PF-16GA_4X10","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309276904.jpg?v=1781062971","url":"https:\/\/voomisupply.com\/products\/southwark-metal-31pf-16ga_4x10-duct-plaster-frame-4x10-16ga","provider":"Voomi Supply","version":"1.0","type":"link"}
