GEZE OL 90N Hand Lever with Corner Bracket Deep Frame White 170mm Opening

Product Overview

GEZE OL 90N Hand Lever with Corner Bracket (White) is used for manual opening of transom windows, specifically in commercial and institutional building environments where deep window frames or restricted installation space are common. The product allows wide opening of the sash, up to 170 mm, while its concealed mounting screws contribute to a discreet installation. This lever is a fit for offices, schools, and laboratories with custom window requirements.

A notable feature is its compatibility with deep window frames, allowing installation without the risk of clearance problems or adaptation delays.
