I'm looking to find out if the dip attachment is compatible with the impulse half rack. Understanding the compatibility is crucial for our setup, so any details on how they work together would be appreciated. Additionally, could you please provide the pricing for the dip attachment? It would be great to know if there are any discounts for bulk purchases or if there are any special offers currently available. Thanks for your assistance!
