SDC EHCPA Replacement Armature Catch Disk | For EH Series Magnetic Door Holders

The SDC EHCPA is a high-quality replacement armature catch disk (catch plate) designed specifically for the SDC EH Series electromagnetic door holders. This precision-engineered component is the essential solution for door restoration when an existing armature plate becomes pitted, magnetized, or lost. By providing a clean, flat surface for the electromagnet to grip, the EHCPA ensures your fire doors remain held open with maximum efficiency, making it a vital solution for commercial door security and life safety compliance.

Precision Performance for Life Safety Systems

The SDC EHCPA is the "contact point" of your door control system. It acts as a proactive solution for door surface repair by restoring the mechanical connection between the door and the wall-mounted magnet:

• Maximum Holding Power: Designed to work with SDC magnets to achieve full holding force (ranging from 35 to 40 lbs for standard units). The smooth finish ensures no air gaps, which are the primary cause of holding force failure.
• Swivel Alignment Technology: The disk features an integrated swivel base that allows the plate to self-align with the magnet face. This compensates for door sag or wall misalignments, ensuring a flush, professional solution for door restoration.
  
• Durable Materials: Constructed from high-quality steel with a corrosion-resistant chrome powder coat finish (689/US28) to withstand the constant "hit and release" cycles of a busy commercial corridor.
• Failsafe Release: Works in conjunction with your fire life safety system. When the fire alarm is triggered and power is cut, the EHCPA releases instantly, allowing the door closer to shut the door and prevent the spread of smoke and flames.

Versatile Installation and Benefits

The SDC EHCPA is a field-installable component that simplifies the maintenance of your facility's fire-rated openings:

• Universal EH Series Fit: This catch disk is the standard replacement for all SDC EH Series models, including EH10 (Flush), EH20 (Semi-Flush), EH30 (Surface), and EH40 (Floor Mount) units.
• Easy Retrofit: Designed to mount directly to the door or to an SDC EHRA extension rod if extra reach is required to bridge the gap between the door and the wall.
• Secure Mounting: The base assembly is designed for stability. For high-traffic or hollow-metal doors, it is recommended to use heavy-duty thru bolts to ensure the plate remains rigid and secure over years of operation.
• Optimized Alignment: When used as a solution for door restoration, this plate helps eliminate "magnet hum" caused by poor surface contact, leading to a quieter and more efficient environment.
