Adjustable Beard Comb 3-7 mm

This replacement comb attaches to compatible shavers and lets you set the cutting length between 3 mm and 7 mm. It works with wet or dry shaving, so you can use it in the shower and rinse it clean afterwards. The black comb is supplied as a single piece and fits the listed prewave models as well as the MG7991, MG7796, MG9730, MG7791/40, MG9000, MG9730/40, MG7791, MG7791/40, MG7796/40 and MG8000 shavers.

For owners of the listed shavers needing a spare

Buyers who own one of the compatible models can replace a lost or worn comb and keep their current length settings. Anyone whose shaver is not in the compatibility list will not be able to attach this comb. Users who need cutting lengths shorter than 3 mm or longer than 7 mm should look for a different accessory.

Adjustable length range 3-7 mm

The comb slides to any setting from 3 mm up to 7 mm, and that range decides whether it matches the beard style you want. If your grooming routine calls for a different minimum or maximum length, this comb will not cover it.

Questions about this item

Which shaver models does the 3-7mm adjustable comb fit?

The comb is compatible with MG7991, MG7796, MG9730, MG7791/40, MG9000, MG9730/40, MG7791, MG7796/40 and MG8000 shavers.

How do I attach the comb to my shaver head?

Align the comb slots with the shaver head tabs and press firmly until you hear a click; the step users miss is not pressing hard enough to lock it in place.

When should I replace the adjustable comb?

Replace the comb if the teeth become bent, cracked or no longer click securely onto the shaver head, as worn teeth cause uneven trimming.
