R-4 Reversible Electric Strike Short Type 12V 3mm Adjustable Latch 300kg Capacity

Product Overview

The Zaczep elektromagnetyczny R-4 short 12 V reversible electric strike is intended for use in access control and intercom door systems, including gates, double-leaf doors, and entryways frequently found in residential and small commercial environments. Manufactured from aluminum alloys with a powder-coated finish, it is corrosion-resistant for outdoor installation provided it is protected from direct flooding or overpainting. The product conforms to the 89/336/EEC directive for electromagnetic compatibility.

A key differentiator for the R-4 is its 3 mm adjustable latch tongue, which compensates for misalignment between the electric strike and door latch. This adjustment helps reduce pressure on the strike mechanism, ensuring consistent operation even with warped doors or frames. Its symmetric, compact design supports both left- and right-hand door installation, making it a strong choice for security system integrators managing varied retrofit or new-build access projects.
