## Description

Achkey Siegenia (SI AUBI) Worm Housing Screw Replacement Part Screwable for Window Gears and Balcony Door Repair Gear Lock for Series Favorit Trial Gearbox 3 & 23 (Pack of 2) with HauSun Upgrade

## Features

- Replacement part Siegenia worm housing: repair replacement housing for defective gears fits many Siegenia gearboxes from the Favourit series.
- Three-piece gear with screws: These are original gear locks, which are converted by us into a repair kit.
- Tool: the gear shells are connected with metric PH screws (PH1). So you only need a PH1 bit or screwdriver (not included).
- Suitable for windows and balcony doors: the gear lock has an adjustment lock, which breaks during the first operation and releases the gearbox.
- Please note: the hole bar can still be used in the gear. If it is heavily worn, the gear can no longer grasp it properly and move it reliably.
