The MyLock 554D is part of the Sailing Line Range and comes fully threaded ready to use with 4 cones of white overlock thread. The feed dog number on the Sailing Line models has doubled to 8-pieces, improving the feeding of various types of fabric. The new style overlock foot gives the user a clear view of the upper knife cutting the fabric; grooves under the foot are for added prevention of fabric slippage; the longer length at the front of the foot with less curve up gives smoother feeding of thicker fabrics and feeding multiple fabric layers.
