This single-gap contact ships in white and installs flush or recessed against a frame surface without requiring routed pockets in the frame itself. It is a low-voltage sensing device used in alarm and access-control circuits. Security installers and low-voltage electricians are the typical trades that handle this component. The trim-style housing keeps the profile clean while maintaining reliable gap sensing for the switch actuation point.\u003c\/p\u003e\n\u003cp\u003eThis contact is suited for residential and light commercial intrusion-detection and access-control systems. It is typically installed on door frames, window frames, or cabinet doors where a clean, finished appearance is required. The surface or hidden-trim mounting style allows use in applications where drilling a deep recess is not practical. Single-gap configuration means one magnet-to-contact pair per installation point.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSurface or hidden-trim mount design allows flexible installation without deep frame routing\u003c\/li\u003e\n  \u003cli\u003eSingle-gap contact configuration for straightforward door or window sensing\u003c\/li\u003e\n  \u003cli\u003eWhite finish for a clean, low-profile appearance on light-colored frames\u003c\/li\u003e\n  \u003cli\u003eLow-voltage compatible for use in standard alarm and access-control circuits\u003c\/li\u003e\n  \u003cli\u003eSold individually for precise quantity ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation surface contact for residential and light commercial door and window alarm circuits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed low-voltage technicians or alarm system installers in accordance with local codes and NEC Article 725 for Class 2 and Class 3 circuits. De-energize the alarm control panel circuit before making wire connections to the contact leads. Mount the contact to the stationary frame and the magnet to the moving door or sash, maintaining the manufacturer-specified gap alignment for reliable actuation. Avoid overtightening mounting fasteners, as this can crack the housing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (EA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Surface \/ Hidden Trim\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGap Configuration\u003c\/strong\u003e: Single Gap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Surface Contacts\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: GEORGE RISK INDUSTRIES INC.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 28A-W\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GEORGE RISK INDUSTRIES INC.","offers":[{"title":"Default Title","offer_id":51696216146226,"sku":"28A-W","price":18.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ec7180d00b7824a8e1ed81c63f01cb3.jpg?v=1788340495","url":"https:\/\/voomisupply.com\/products\/gri-28a-w-surface-contact-1-gap-white","provider":"Voomi Supply","version":"1.0","type":"link"}
