Spacer plate or knob adapter?
Two parts, two tasks. The spacer plate creates the support at the door. The knob adapter connects the cylinder shaft to the drive of your Smart Lock.

A gap behind the castle?
A spacer plate compensates for the distance between the door or fitting and the mounting plate. First choose your lock and then the profile of your rosette. The plate thickness follows the cylinder overhang; an additional lip does not belong to this dimension.

The drive does not fit on the shaft?
A knob adapter transfers the rotary movement to the existing cylinder shaft. Manufacturer, waveform and dimensions must match the adapter. It does not replace a spacer plate. Depending on the door, you may need both parts.

- Zylinderüberstand: Measure from the support surface of the fitting to the front side of the cylinder. Without attached hardware, the door surface is the reference point.
- Rosette: For a long shield measure the width at the cylinder, for a round rosette the diameter. The height is measured from the door surface.
- Wave: For a knob adapter, match the shape, width or diameter and existing cross holes with the respective product.
Choose the right profile
An EU profile, a long plate and a Swiss round cylinder require different openings. In the Swiss 22, cylinder body and shaft are not on the same axis. Choose the profile based on your door, not just the lock brand.
Check the print run and the measurement lines in the 3D view. The Smart Lock is displayed for installation control and is not included in the delivery. After installation, check with the door opened if the lock locks and unlocks freely.
