Key Features

• Direct compatibility: Designed as a replacement for 2105300125A and stens 355-101, so it fits many Hyper Tough and Dype decks with an oval center hole.
• Standard dimensions: The 20in length, 2-1/4in width and 0.125in thickness match original equipment sizing for a predictable fit and cutting geometry.
