It mounts on the push side of the door and accepts a full cover for a clean, finished appearance. The size range of 1 through 6 makes it adjustable for a wide variety of door weights and widths. This closer is non-handed, meaning it works on both left-hand and right-hand swing doors without requiring separate SKUs. It ships with an aluminum painted finish. Licensed contractors and commercial door hardware installers are the typical trade professionals who specify and install this unit.\u003c\/p\u003e\u003cp\u003eThis door closer suits commercial buildings, institutional facilities, schools, hospitals, and office environments where Grade 1 hardware is required by code or specification. The push-side mount is the standard parallel-arm or regular-arm configuration used when the closer body is mounted on the push face of the door. The non-handed design simplifies procurement for jobs requiring multiple units across mixed door swings. The full cover conceals the closer body and arm mechanism for a more refined finished look.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 1 certified for heavy-duty commercial use and long cycle life\u003c\/li\u003e\n\u003cli\u003eSize 1-6 adjustable closing force accommodates a wide range of door sizes and weights\u003c\/li\u003e\n\u003cli\u003eNon-handed design installs on left-hand or right-hand doors without modification\u003c\/li\u003e\n\u003cli\u003ePush side mount is the standard regular-arm configuration for push-face installation\u003c\/li\u003e\n\u003cli\u003eFull cover included for a clean, professional appearance on the finished side\u003c\/li\u003e\n\u003cli\u003eAluminum painted finish (689) blends with common commercial door frame finishes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style surface door closer for commercial and institutional doors requiring Grade 1 hardware with a push-side regular-arm mount configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed door hardware installer or commercial locksmith in accordance with the door manufacturer specifications and applicable building codes.
