Easy to install. Stick on the template, drill the screw holes, and start the hole saw. Important! Drill the screw holes first! The hole saw won't leave much of the self-adhesive template.

Pre-drill the two recesses for the counter ring with progressively larger drill bits and enlarge them to the correct size with a round file.

Screw connection insufficient
The product is good. The installation instructions are also helpful. However, the screw connection is not good. Spax screws are used for installation, which are screwed into the sealing ring. I couldn't tighten the screws enough to prevent water from escaping through the screw seal. The only way to solve the problem was to seal the screws from above with sealant.
