12 years ago, the Model 501 was added to our standard line of belts to offer more comfort and back support with our 3“ belt without the added weight of extra nail pouches. Now, the new Premium 501 model has all the attributes of the original 501 but has Premium added features, such as industry requested Drill Clip holders located above each of the hammer loops, and small tool-bit holders to keep the versatile trades person equipped for every situation. If you are looking for a front-buckle, back-wearing apron/belt without the added weight of extra nail pockets, this is the model for you!
