Baltimore Street Irons Front and Back Springs for Lining — Three Size (Thickness) Options

Baltimore Street Irons gives us quality and precision with their Lining Front and Back Springs. The Springs are cut while completely submerged, so there is no heat transfer to the metal during the process. This allows for no loss of temper in the steel. These lining springs come in three sizes (thicknesses): 0.020g, 0.018g, and 0.015g. The thin spring measures 34mm long, while the fatter spring measures 45mm long. The tabs are sent flat, allowing you to use O-rings if you choose.
