With a minimum load capacity of 40,000 pounds, this screw jack handles substantial compressive loads in demanding job site environments. The base diameter measures 2.75 inches, and the height adjusts from 4 inches to 9.5 inches, giving installers flexibility across a range of structural clearances. Licensed contractors, pipefitters, and construction tradespeople rely on this type of support jack when temporary or permanent adjustable shoring is required beneath equipment, beams, or structural loads.\u003c\/p\u003e\n\u003cp\u003eThis screw jack is suited for residential and light commercial applications where adjustable point-load support is needed. Typical install scenarios include supporting HVAC equipment on uneven surfaces, pipe and equipment shoring during service, and leveling mechanical systems in crawl spaces or mechanical rooms. The adjustable height range accommodates variations in floor-to-framing clearances without the need for custom fabrication or shimming.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMinimum load capacity of 40,000 pounds for heavy structural support applications\u003c\/li\u003e\n  \u003cli\u003eAdjustable height range from 4 inches to 9.5 inches for flexible fitment\u003c\/li\u003e\n  \u003cli\u003e2.75 inch base diameter provides stable footing on flat bearing surfaces\u003c\/li\u003e\n  \u003cli\u003eScrew-jack design allows precise height adjustment in the field\u003c\/li\u003e\n  \u003cli\u003eCompact footprint suits tight mechanical spaces including crawl spaces and mechanical rooms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose support screw jack suited for HVAC equipment staging, mechanical systems support, and structural shoring applications requiring adjustable point-load capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with load-bearing and shoring requirements. Always ensure the bearing surface beneath the base is level, clean, and capable of supporting the applied load before placing the jack under load. Shut off and de-energize any associated mechanical or electrical equipment before working in the immediate area. Consult applicable local building codes and structural guidelines before using screw jacks in permanent load-bearing applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Capacity\u003c\/strong\u003e: 40,000 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight Range\u003c\/strong\u003e: 4 inches to 9.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MAS-0400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51696628859186,"sku":"MAS-0400","price":566.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88300b5968f0f3b123f57a3185daa26e.jpg?v=1788344626","url":"https:\/\/voomisupply.com\/products\/gibraltar-mas-0400-support-screw-jack-40000-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
