Base Plate for Alva Self-Closing Patch Fitting
The self-closing Alva patch fitting is fixed to the ground with only two instead of four screws and the aid of a base plate. To make drilling into the substrate as convenient as possible, there is a distance of 1-1/8" (29 mm) between the wall and the first drill hole, leaving enough space for the drilling machine.
- Precise positioning of the door with the aid of four adjusting screws
- Zero position adjustment of up to ± 1/8" (± 3 mm)
- Adjustment of the wall distance with a fifth adjusting screw.
