Coupling hook for older windows. A traditional variant that works well for connecting windows.

A hole for fixing, then you let the hook step over the screw head of the corresponding sash and lock it that way.

Window lock with hook for outward opening windows. Nickel-plated brass. Screw included.

The eyelet hook is the intelligent window fitting from around 1920 onwards. The eyelet hook is mounted on the sash of a single or coupled window, and has an adjustable screw that allows you to always get the window tight, even if the sash is slightly skewed or the seal uneven. Very suitable for use in combination with Gysinge’s wool sealing strips.
