The Slammer Hammer squeegee comes with a 4.5" Sledgehammer (93 Durometer) insert blade.

This squeegee is very convenient to use due to its lighter weight, and is a great alternate choice to the main handle squeegee for all side door windows and even on the back windshield.

TheRigid and durable Sledgehammer  blade is infused with slip additives, which makes the Slammer Hammer Glide like silk while removing maximum mounting solution.
