Used when standard armature positioning does not provide proper alignment between the door holder and armature plate, these extension bars allow precise positioning for optimal magnetic contact and full holding force. Available in four lengths to accommodate a wide range of door frame configurations, wall depths, and mounting requirements in residential, commercial, and public area access control applications. Always confirm the required extension length by measuring the gap between your door holder and armature plate before ordering.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eExtension bar for precise armature positioning on SECO-LARM door holders\u003c\/li\u003e\n\u003cli\u003eAvailable in four lengths to accommodate varying mounting configurations\u003c\/li\u003e\n\u003cli\u003eEnsures proper magnetic contact between door holder and armature plate\u003c\/li\u003e\n\u003cli\u003eMaintains full 33 lb holding force when properly installed\u003c\/li\u003e\n\u003cli\u003eCompatible with DH-151SQ and DH-171SQ magnetic door holder assemblies\u003c\/li\u003e\n\u003cli\u003eVerify required extension length prior to purchase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eModels and Variants\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDH-100E-07SQ\u003c\/strong\u003e - 3\/4 in (19mm) extension bar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDH-100E-10SQ\u003c\/strong\u003e - 1 in (25mm) extension bar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDH-100E-40SQ\u003c\/strong\u003e - 4 in (102mm) extension bar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDH-100E-70SQ\u003c\/strong\u003e - 7 in (178mm) extension bar\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Family:\u003c\/strong\u003e DH-100E series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Armature extension bar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Lengths:\u003c\/strong\u003e 3\/4 in, 1 in, 4 in, 7 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e SECO-LARM DH-151SQ and DH-171SQ magnetic door holders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e SECO-LARM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New, genuine OEM part\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConclusion\u003c\/h3\u003e\n\u003cp\u003eFor magnetic door holder installations requiring additional armature offset, SECO-LARM DH-100E extension bars provide factory-spec positioning and proper alignment for consistent magnetic engagement.
