Adjustable beard comb 3–7 mm
This replacement comb fits the listed prewave shaver models and provides an adjustable cutting length from 3 mm to 7 mm. It is designed for owners of the BT3236, BT3237, BT1217/70 or MG series trimmers who need a new guide comb. The part supports wet and dry use for shower grooming or dry trimming.
Snap-on installation
The comb clips onto the shaver head without tools and locks into the length adjustment mechanism. Misalignment during fitting can prevent the comb from seating fully, which may cause uneven cutting or the comb to detach during use. Rinse the comb and shaver head under running water after each session to avoid hair build-up that stiffens the slide.
Fixed length range
The comb only delivers lengths between 3 mm and 7 mm, so users wanting stubble shorter than 3 mm or a full beard longer than 7 mm cannot achieve those results with this accessory. It is a single-piece guide with no interchangeable spacers, limiting styling flexibility to the built-in adjustment steps. The part is intended solely as a direct replacement for the original comb supplied with the compatible shavers.

Questions about this item
How do I verify the comb is cutting at the right length after attaching it to my shaver?
Trim a small test patch and measure the stubble; it should fall between 3 mm and 7 mm if the comb is seated correctly.
What comes in the package and do I need any extra parts to use it?
The box contains one adjustable beard comb; no additional accessories are required for installation.
Which comb version should I pick for my MG3721 shaver?
This single adjustable comb fits the MG3721 and all other listed models, so no separate version choice is needed.
