Openers & Closers 54E21 Electric Strike 12V DC Reversible Narrow Profile TSV Surge Protection

Product Overview

Elektrozaczep Openers & Closers 12V DC rewersyjny z wyślizgiem (54E21) is an electric strike used for access control on narrow-profile doors in commercial and institutional settings. The unit operates on direct current (DC) at 12V, features a radial and symmetrical design for flexible installation, and includes TSV surge protection for improved electrical safety in modern access systems.

The primary advantage of this SKU is its reversible action with a 13 mm latch cut, enabling compatibility with multiple lock types and reducing site-specific procurement risks for installers managing both inward and outward opening doors. Its continuous DC operation of less than one minute and integrated surge protection make it particularly suited for high-turnover entryways in commercial offices and institutional buildings where reliability and protection against power fluctuations are critical.
