This rubber block is extremely handy on the bench, for filing, hammering and other uses. Made of tough, firm, vulcanized rubber, it measures 4"x4"x3/4" to give you an excellent work surface.
It allows you to remove dents and straighten metal without the fear of scratching or distorting. It can also be used to secure items for filling. Another great thing about this block is that it's sound absorbing, try placing your regular steel bench block on top while you're working.
