BIRA OK-P4 electric strike mounting plate, OK-P4, BIRA

The BIRA OK-P4 is a galvanized steel mounting plate designed for use with electric strikes, especially with the HARTTE S/XS series. With dimensions of 250 × 25 × 3 mm, it provides a solid and stable base for installing a strike in metal or aluminum door frames. The plate is suitable for doors and gates where a reliable mounting surface is required.

Main features

Technical characteristics

The mounting plate is made of galvanized steel, providing strong corrosion resistance and long-term durability. Its 250 mm length and 25 mm width offer sufficient surface area for secure fastening of the electric strike, while the 3 mm thickness ensures rigidity and stability even in frequently used doors.

Installation and compatibility

The OK-P4 mounting plate is installed together with the electric strike, acting as a reinforcing base or an adapter between the strike and the door frame. It is suitable for metal and aluminum profiles and is ideal for retrofit projects where the original frame cut-out does not match the new strike dimensions. The plate can be drilled or adjusted on site for precise installation.
