Product Overview

The dormakaba OGRO Base-4 Lever-Knob on long plate is a stainless steel handle set designed for fire-rated and smoke-control doors in commercial and institutional buildings. It features a right-hand configuration, 72 mm cylinder spacing (WB), and a reinforced 9 mm spindle approved for installation with cylinder lock inserts. Certified to EN 1906 (class 4), DIN 18273, and EN 179, this hardware achieves high corrosion resistance and is tested for 200,000 cycles, making it suitable for demanding environments.

What distinguishes the OGRO Base-4 set is its 9 mm spindle, which enables fire and smoke door certification per DIN 18273 and EN 1906 with documented performance from MPA NRW (certificate 123001163-01). This eliminates compliance risk for locksmiths, facility managers, and OEM buyers needing hardware for regulated fire-protection installations. The product is especially well-suited for bulk procurement in fire-rated commercial projects, public-sector buildings, and professional security upgrades.
