10-Position Guide Comb for T-Blade Trimmers

This prewave guide comb fits Wahl high-performance trimmers equipped with a near-zero-gap DLC T-blade. It provides ten adjustable cutting lengths from 12 mm to 21 mm in one-millimetre steps. The attachment is designed for wet or dry use, so it can be used in the shower and rinsed clean afterwards.

Sustained wet-and-dry operation

The comb maintains its position securely during extended grooming sessions whether the trimmer is used dry or under running water. Its construction resists moisture and allows easy cleaning between passes without the attachment loosening or shifting. This stability supports consistent length results throughout a full beard or hair trim.

Replaces fixed-length combs for T-blade owners

The single attachment replaces a set of individual guide combs for users who want variable length control from 12 mm to 21 mm. It is not compatible with standard square blades or the listed Wahl models such as 5621, 8900, 9900 and others. Buyers needing shorter stubble settings or compatibility with square-blade trimmers will need a different accessory.

Questions about this item

Does the 10-position guide comb add any noise or heat to the trimmer during long sessions?

The comb is a passive plastic attachment with no motor or electronics, so it does not increase noise, heat or power draw.

Which trimmer must I already own for this 12-21mm comb to fit?

It fits Wahl high-performance trimmers equipped with the near-zero-gap DLC T-blade or extreme-precision T-blade; it will not fit standard square-blade models such as 5621, 5622, 5623, 8040, 8064, 8900, 9300, 9307, 9326, 9878, 9900, 9906, 9910, 9916, 9918, 9920, 9925, 9940, 9961, 9962, 9966, 9971, 9985 or 9990.

Can I keep using my older Wahl square-blade trimmer with this comb?

No — the comb is designed only for T-blade stainless-steel or extreme-precision T-blade trimmers and is explicitly listed as incompatible with square-blade models.
