9-13mm Adjustable Beard Comb

This adjustable beard comb attaches to compatible shavers and lets you select cutting lengths between 9 and 13 millimetres. It fits the BT3125, BT3207, MG5730, MG5735, MG5740, MG7770/15, MG7770/28, MG5750, MG7796/40 and MG8000 models. The comb is designed for wet or dry use. Buyers needing lengths outside the 9-13mm range or a comb for other shaver series cannot use this part.

Wet and Dry Shaving Compatibility

The comb supports both wet and dry operation, so it can be used in the shower and rinsed clean under running water. Its plastic construction tolerates moisture without corrosion. No electronic interface or powered mechanism is involved; the comb simply clips onto the shaver head. Users who require a vacuum-assisted trimming system or a motorised length adjustment will not find those features here.

Simple Clip-On Installation

Installation consists of aligning the comb with the shaver head and pressing until it clicks into place. The package includes one comb unit. The most common issue is selecting the wrong model number, which prevents the comb from seating correctly. Forcing a mismatched comb can damage the mounting tabs on either the comb or the shaver.
