Prewave 12-21mm 10-Position Guide Comb

This Prewave guide comb attachment provides ten distinct cutting lengths ranging from 12mm to 21mm for compatible Wahl shavers. It is designed for men who need precise beard and hair trimming options with a single accessory. The comb supports both wet and dry operation for use in the shower or easy rinsing. Buyers with incompatible shaver models listed in the specifications cannot use this attachment.

Wet and Dry Use With Simple Maintenance

The attachment is built for wet and dry use, allowing operation in the shower and straightforward cleaning under running water. No thermals, noise metrics or power draw figures apply to this passive plastic comb accessory. It adds no electrical load or sound to the shaver itself during normal grooming sessions. Users seeking active cooling or motorised adjustments will not find those features here.

Questions about this item

How do I attach the 12-21mm guide comb to my Wahl shaver without it coming loose?

Align the comb's slots with the shaver head clips, press firmly until you hear a click, and verify it sits flat before trimming; the most common error is stopping at the first resistance instead of pushing to the second click.

When should I replace the 10-position guide comb attachment?

Replace it if the length selector clicks become vague, the comb teeth bend or crack, or hair starts catching between the comb and the blades during wet or dry use.

What limits the cutting length range during a long grooming session?

The comb locks at 10 fixed settings from 12mm to 21mm in 1mm steps, so you cannot trim shorter than 12mm or longer than 21mm with this attachment.
