Sdc EHR3A Extension Rod 3 Inch Chrome Door Closer

Product Description

The SDC Security Door Controls EHR3A is a 3-inch extension rod finished in chrome, designed to extend the reach of compatible door closer arms. It is used when standard arm lengths are insufficient for proper door closer installation, allowing technicians to achieve correct geometry between the closer body and the door or frame. The chrome finish provides corrosion resistance suitable for interior and light commercial applications. Installation is handled by locksmiths, door hardware technicians, or commercial general contractors working on door closer systems.

The EHR3A is applicable in commercial and institutional settings where door closers require additional arm extension to meet the required backcheck or sweep geometry. It is commonly used in retrofit situations where existing door frames, transoms, or door widths fall outside the range of a standard closer arm. This accessory fits into the door closers and holders product category and is sold as an individual unit.

Installation Notes

Installation is performed by a licensed locksmith or qualified door hardware technician. Before servicing or replacing door closer components, ensure the door is held open safely and the closer is depressurized or disengaged per manufacturer instructions. Standard hand tools are typically sufficient for rod attachment and adjustment. Verify final arm geometry and sweep speed after installation to ensure the closer operates within building code requirements.
