DynaLock 2864 Armature Extension 2

Optimize door security installations with the DynaLock 2864 armature extension rod — a practical solution that gives installers extra reach to accommodate offset frames, deep jambs, and uneven door conditions. This armature extension rod is engineered specifically for use with DynaLock 2800 Series electromagnetic door holders (Mfr. P/N 2864), providing seamless compatibility with systems that accept tri-voltage inputs (12V DC, 24V AC/DC or 120V AC). By extending the armature position, the 2864 reduces field modifications and accelerates retrofits for single and double door applications.

Built to perform in commercial and institutional environments, the extension supports installations paired with standard holders (30–45 lb holding force) as well as high-security models used where greater magnetic retention is required. Its durable, low-profile design preserves the visual integrity of monitored entrances while improving reliability for access control, security monitoring, and surveillance-focused door systems. Ideal for schools, hospitals, office buildings and retrofit projects — add the DynaLock 2864 armature extension rod to your next job to streamline installation and enhance door security.
