Sized at Size 4, this unit mounts to the door frame header or soffit and engages a shoe on the door itself, physically limiting travel at the selected hold-open or stop position. It carries an aluminum painted finish and is non-handed, meaning a single unit works on either a left-hand or right-hand door without modification. This type of hardware is standard in commercial and institutional construction where durable, reliable door control is required.\u003c\/p\u003e\u003cp\u003eSurface overhead stops are commonly specified in commercial interiors including offices, schools, healthcare facilities, and government buildings where wall-mounted door stops are not practical or code-compliant. A Size 4 unit is appropriate for heavier commercial doors and wider door widths where smaller stop sizes would be undersized for the load. Installation is performed by finish carpenters, door hardware installers, or general contractors during the door and frame finish-out phase of a project.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHeavy duty construction rated for demanding commercial door applications\u003c\/li\u003e\n\u003cli\u003eSurface-mounted overhead stop design protects frames, walls, and adjacent hardware\u003c\/li\u003e\n\u003cli\u003eSize 4 classification suitable for heavier commercial-grade doors\u003c\/li\u003e\n\u003cli\u003eAluminum painted finish for a clean, professional appearance\u003c\/li\u003e\n\u003cli\u003eNon-handed design installs on left-hand or right-hand doors without modification\u003c\/li\u003e\n\u003cli\u003eStop-only function provides positive door travel limitation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation surface overhead stop for commercial door assemblies requiring a Size 4 non-handed unit with an aluminum painted finish.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a qualified door hardware installer or finish carpenter following the door manufacturer and hardware manufacturer template instructions.
