it's glued in and mine is not square with the pins anyways so it can't be level and the pins run straight with the string. I canted the housing to make it work. You could try and heat the glue. Then again mine is a few years old and they may have changed them to a removable one, AND ADDED STAINLESS STEEL SCREWS INSTEAD OF STEEL ONES (for anyone from cp who maybe reading this)[:@]
