This blue color-coded left block adds convenience to your blocking routine, making it easier to find the right block. An added measuring line provides efficiency and convenience to the use of liquid and powder adhesives. This line eliminates the need to use a separate mixing cup, saving you both time and money. The added thickness to the block helps ensure the cow will not stub the injured claw on any potential farm obstacles throughout the healing process. Angled toe design helps eliminate the block catching on potential farm obstacles that would peel the block away from the hoof prematurely. Coarse points of contact allow for advanced adhesion. UltraBlock offers an optimal fit and support to prevent tendon damage and enhance the healing process for treated cows.
