Wahl’s Standard Adjustable Replacement Blades are for use on the Wahl U-Clip®, Deluxe U-Clip®, Pro Ion®, Show Pro® Plus, and Iron Horse™ clippers. The adjustable taper lever on the side of the clipper makes it easy to adjust to the desired blade size. Available in both a standard and an extra wide size that adjust between cutting lengths #30, #15, and #10. Need additional cutting lengths? Wahl has two Replacement Guide Comb sets that provide additional cut lengths that let you keep up to 1 inch of hair. The guide combs are easy to attach to your Standard Adjustable blades and glide effortlessly through coats, leaving a smooth finish and the length you need.
