dormakaba OGRO Base-4 Lever-Knob Set Long Escutcheon INOX EN 1906 Class 4 Right 8mm

Product Overview

The dormakaba OGRO Base-4 lever-knob set with long escutcheon (72 WB, 8 mm spindle, right, INOX) is designed for installation on doors equipped with a cylinder lock (PZ profile), including those requiring fire safety compliance in commercial and institutional environments. Manufactured from stainless steel in a satin silver finish, this handle meets EN 1906 (Class 4) for intensive usage and very high corrosion resistance, and is suitable for doors in areas with demanding conditions. Certifications also include DIN 18273 and EN179, supporting use in fire-rated, smoke-control, and emergency exit doors.

This specific variant, featuring an 8 mm spindle, does not carry the fire safety certificate (certified only for the 9 mm spindle variant), but retains high durability and safety compliance for standard and smoke-control door applications. The integrated return spring ensures consistent handle positioning, minimizing maintenance concerns for facility managers. Particularly suited for bulk procurement in commercial construction and retrofit projects requiring robust, corrosion-resistant hardware without mandatory fire rating.
