We are moving away from carrying the electronic components that make up the Servo-Drive system. All of our trash pullout cabinets are still drilled to accept Servo-Drive; however, to purchase the actual unit, we recommend ordering it directly from Amazon. They are typically more competitive on price, and if you encounter any issues, returns are straightforward with a Prime membership.
These units can be somewhat temperamental, but once properly set up and adjusted, they are excellent in terms of quality and performance.
On Amazon, search for “Blum Z10NA30UGUS TANDEM SERVO-DRIVE” to find the correct unit.
