7 mm bi-directional comb for Bodygroom shavers

This 7 mm black plastic comb snaps onto compatible Bodygroom models to set a fixed cutting length for beard or body grooming. The bi-directional teeth feed hair evenly whether you move the shaver with or against the grain. It is a direct replacement part for the original comb that shipped with the device. Wet and dry use is supported for shower grooming and simple rinsing.

Replaces a lost or worn original comb

When the factory comb cracks, warps or goes missing this part restores the 7 mm cutting length without buying a new shaver. The upgrade is worth it if the existing comb no longer clicks securely or its teeth are bent enough to pull hair. Models covered include BG3017, BG3027, BG5020, BG5021, BG5025, BG9040 and SBG315 plus the 5025/40, 5025/49, 5021/15 and 5020/13 variants.

Fixed 7 mm length only

The comb locks the trimmer to a single 7 mm setting so it cannot produce shorter stubble or longer beard lengths. Buyers who want adjustable lengths or multiple guard sizes need a different accessory system. The plastic construction is not designed for heavy impact or high-temperature sterilisation beyond normal shower use.
