R-4 Short Electromagnetic Strike 24V Symmetrical Universal Aluminum 22x30x69mm

Product Overview

Zaczep elektromagnetyczny R-4 is a compact, symmetrical electromagnetic strike designed for two-leaf doors, access gates, and doorphone systems in residential, commercial, and outdoor environments. Manufactured from corrosion-resistant aluminium alloys with a powder-coated finish, it complies with directive 89/336/EEC and installs in a 22x30x69 mm socket. Its 24 V operating voltage and regulated tongue adjustment provide reliable function even under variable conditions and misaligned frames.

The key differentiator of the R-4 is its symmetrical form factor, which enables installation on both left- and right-handed doors without additional hardware or complexity. This reduces procurement risk and installation time, especially for contractors managing bulk installations or refurbishments in multi-unit dwellings and access control projects. Particularly recommended for access control and intercom systems where versatility and compactness are required.
