Frames Put on a Strap

In the case of windows with frames put on a strap, the transparent strap holding the window runs behind the frame. The frame is attached to the strap using two U-shaped guides. This design allows the window to slide smoothly along the strap. Our frames are hot-formed, which ensures excellent shape stability so that the window sits perfectly flat against the calendar sheets.

Type N frames, designed to be put on a strap, can be used with the following types of straps:

date sliders (windows) with rubber band
date sliders (windows) with textile rubber and metal crimps
date sliders (windows) with tied textile rubber
rubberless straps (windows)
