R-4 Electromagnetic Strike Release Short 12V Symmetrical 3mm Latch Adjustment

Product Overview

The Zaczep elektromagnetyczny R-4 krótki 12 V is a compact, symmetrical electric strike release designed for securing and remotely unlocking gates, double-leaf doors, and intercom system doors. Constructed from corrosion-resistant aluminum alloy with a powder-coated finish, it is suitable for indoor and outdoor installation in access control and intercom environments, provided it is protected from direct flooding. The device complies with Directive 89/336/EEC for electromagnetic compatibility.

Its key distinguishing feature is the 3 mm adjustable latch tongue, which allows for fine-tuning to eliminate play between the strike and door latch, greatly minimizing pressure on the locking mechanism and ensuring reliable operation even with warped frames or misaligned doors. This makes the R-4 model well-suited for integrators managing retrofits or installations where door or frame deformation might otherwise compromise lock reliability, and for bulk procurement by installers serving both left- and right-handed doors.
