Brass is an alloy (mixture) of copper and zinc. In Swedish brass (as in our fittings), the copper content is around 70% and the zinc content around 30%, which makes the fittings heavy and solid and the brass color deep.

An elevation plate or spacer plate is often needed when installing a weatherization fitting on inward opening windows. The thickness of the sash and the distance to the window frame can vary and an elevation plate helps to mount in a neat way. Usually there is a difference of about 5-20 mm and then you need to buy corresponding elevation plates to ensure a good installation.

Elevation washers may also be needed when installing weatherization fittings for outward opening windows. For example, when you have stucco or profiles in the window sash or window sill that do not allow you to mount the weatherization fitting where you want.

Window lock with hook for outward opening windows. Untreated 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.
