This compact pry bar adaptor head is designed to allow any 3/8" Drive breaker bar or ratchet to be used for prying and lifting. The low profile design, combined with the 8 point (double square) drive, allows for it to be used in a wider variety of positions than a traditional fixed head pry bar and ideal for use in hard to access areas. The double square drive allows you to position it precisely. Ideal for use in tight spaces. Manufactured from SCM440 steel for strength (hardness 40-44), with a nickel plated finish.
