Hey pet groomers! This WAHL stainless steel attachment comb is exactly what you need for professional-looking pet haircuts. It gives you a perfect 3/8 inch cut length (that's about 10mm) every time, and the dark blue color makes it easy to identify quickly. The best part? It snaps right onto your Wahl clippers - compatible with SS-Pro, KM 2, KM 5, KM 10, Power Grip, and KM Cordless models. For the smoothest cuts, use it with Wahl's #30 Ultimate or Competition Series blades, though it also works with #15 or #10 blades. Just a heads up - don't use it with the #40 blade series. Made from durable stainless steel that'll last through countless grooming sessions. If you need different lengths, Wahl offers other combs separately ranging from 1/8 inch all the way up to 1 inch. Whether you're a professional groomer or just keeping your own pets looking sharp, this attachment makes achieving consistent lengths so much easier. It's one of those simple tools that seriously upgrades your grooming game!
