Machined from aluminum with a clear anodized finish, this bracket creates rigid 90-degree inside corner connections between profile members. It features a 2-degree drop-lock mechanism that allows the bracket to seat and lock positively into position along the T-slot, reducing installation time and improving alignment accuracy. Eight mounting holes distribute load across the connection point for a secure structural joint. Licensed HVAC and mechanical installers, machine builders, and industrial fabricators commonly work with 80\/20 framing systems in equipment enclosures, workstations, and support structures.\u003c\/p\u003e\n\u003cp\u003eThe 25-4138 is intended for use with 80\/20 25 Series T-slot aluminum extrusion profiles and requires Bolt Kit 75-3404 for complete installation. It is suited for both light-duty and moderate structural framing applications in industrial, commercial, and laboratory environments. The bracket positions along the profile T-slot, giving the installer flexibility in locating the connection point before final fastening. This inside corner orientation is appropriate where external gusset access is restricted or where a flush exterior profile face is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree inside corner connection for T-slot aluminum framing assemblies\u003c\/li\u003e\n  \u003cli\u003e2-degree drop-lock design seats and locks into the T-slot channel for accurate positioning\u003c\/li\u003e\n  \u003cli\u003e8 mounting holes for secure, distributed load transfer at the joint\u003c\/li\u003e\n  \u003cli\u003eClear anodized aluminum construction resists corrosion and wear\u003c\/li\u003e\n  \u003cli\u003eSlides and positions along the profile T-slot prior to final fastening\u003c\/li\u003e\n  \u003cli\u003eCompatible with Bolt Kit 75-3404 for complete hardware assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 80\/20 25 Series T-slot aluminum extrusion profiles. Requires Bolt Kit 75-3404 for installation. Verify profile series before ordering, as T-slot bracket dimensions are series-specific and are not interchangeable across different profile sizes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical assemblers, millwrights, or fabricators familiar with modular aluminum framing systems. Before modifying an existing assembly, relieve any load on the framing members being joined. Slide the bracket into the T-slot channel, position it at the desired location, then secure using the appropriate hardware from Bolt Kit 75-3404 per standard framing assembly practice. Follow the equipment manufacturer's torque and assembly guidelines provided with the bolt kit documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: Inside Corner Gusset Bracket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Clear Anodized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Clear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Mounting Holes\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.96 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Series 25 and Bolt Kit 75-3404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 24102004\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: 80\/20 INC.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 25-4138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"80\/20 INC","offers":[{"title":"Default Title","offer_id":67913428074802,"sku":"25-4138","price":24.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90d401a9fec5eda2dfcdff190db111d0_1ead8d5f-7a71-446c-ad9f-8577a0829d15.jpg?v=1791245391","url":"https:\/\/voomisupply.com\/products\/80-20-inc-25-4138-inside-corner-gusset-bracket-series-25","provider":"Voomi Supply","version":"1.0","type":"link"}
