Wahl Stainless Steel Attachment Combs Kit for Detachable Blades is a set of color-coded combs with eight cutting lengths for a 1/8” to 1” cut. These combs should be used with the Wahl Competition Series #30 blade set for best performance, but can also be used with any #10, #15 or #30 blade. Wahl’s Stainless Steel Attachment Combs are effective for grooming pets and coats of all types. They are made to glide through coats, leaving a smooth finish and no clipper marks. The snap-on feature gives a secure, four-sided fit to help prevent clipper accidents.
