The Baby Lock Serger Swing Guide fits models: BLES8, BLETS8AE, BLETS8, BLCS, BLCS2, BLP6, BLC4, BLE8, BLE8W, BLE8W-2, BLS8. This adjustable guide acts as a platform for many of the Baby Lock serger attachments when the attachment is secured to the swing guide. With the attachment in position simply swing the guide away from the machine to easily position the fabric in the attachment. Move the swing guide toward the machine and the attachment and align it with the needle. In just a few steps the attachment is ready to use. Note: The Swing Guide works with the Overlock Table – BLA-OLT. For Ovation models without the two sets of positions on the flat sewing table, BLES8-CST will be needed to use this attachment.
