Yep. Not a problem. However in my opinion you are wasting good $$$. THee so called "Rack Blocks" are over priced. A great mix that works just as well and is only a fraction of the cost is a mix of plain salt, dicalcium phjosphate and a high calcium "dairy" cattle supplement. You can get 50# of each for about $45 (150# total). Hand mix 1-1-1, and put it out 25#/spots.
