ESSVE Programa Universal key UN-T is intended to fine adjust window and door frames by hand after installation of Programa Frame screws
or Indu-Prog Frame Sleeves. UN-T can also be used for installation/screwing.

The square part is used to open windows and doors without handles. Also provides a good lever during installation/adjustment.

The end with the internal hex key is used for installation, this then grips both the sleeve and screw when screw together. The end which is bored out on the inside is used for adjustment, this only grips the sleeve to screw in or out.
