In a sea of orange smocks, the Hilti store-within-a-store format at many Home Depots had injected a splash of red-shirted Hilti sales reps.

That color combination is fading to black, as Tulsa, Okla.-based Hilti’s “Proshops,” as they are called, are pulling out of the world’s largest home improvement retailer.

The Hilti Proshops had been a fixture at Home Depot for about 13 years. Hilti products will continue to be available online through the Atlanta-based retail giant.
