Product Details

The B1511-773-0A0 presser foot is a replacement work clamp attachment for 781-style industrial buttonhole sewing machines. It is designed to hold the garment securely during the buttonhole sewing sequence, helping maintain stable fabric positioning and consistent buttonhole formation.This buttonhole presser foot is compatible with Juki LBH-781, LBH-771, LBH-772, LBH-780, LBH-782 and LBH-783 series machines, as well as Jack JK-T781, Taking TK-781 and Zoje ZJ-781 models according to the supplied compatibility information.If your existing work clamp or presser foot is worn, damaged, or no longer holding fabric firmly, this replacement can help restore reliable clamping performance.Why Choose This Buttonhole Presser Foot?Buttonhole machines depend on secure fabric clamping throughout the sewing cycle. If the work clamp does not hold the material properly, the fabric can shift and affect the appearance and positioning of the finished buttonhole.The B1511-773-0A0 is designed as a direct replacement for the applicable 781-style work clamp arrangement. Its firm clamping action is useful for repetitive garment production where buttonholes must be made consistently across multiple pieces.The smooth underside also helps reduce unnecessary contact marks, pulling, or snagging when working with suitable garment fabrics.Key FeaturesPart Number: B1511-773-0A0Alternate Part References: B15117730A0 / B1511-773-AType: Buttonhole presser foot / work clamp attachmentPack Quantity: 1 pieceHigh-precision fabric clamping during buttonhole sewingLarge-size work clamp configuration for applicable buttonhole applicationsWear-resistant steel constructionSmooth finished undersideSuitable for repetitive industrial garment productionDirect replacement design for compatible 781-style machinesMachine CompatibilityThis replacement presser foot is intended for the following buttonhole machine models:Machine Type CompatibleJuki LBH-781 YesJuki LBH-771 YesJuki LBH-772 YesJuki LBH-780 YesJuki LBH-782 YesJuki LBH-783 YesJack JK-T781 YesTaking TK-781 YesZoje ZJ-781 YesOther 781-style buttonhole machines Verify before purchaseImportant: Please verify the shape and measurements of your existing presser foot or work clamp before purchasing, especially when using a machine model outside the listed compatibility range.Best Fabric TypesThe B1511-773-0A0 is suitable for common woven garment materials used with industrial buttonhole machines.Cotton: Suitable for shirts, uniforms, workwear, and other woven cotton garments.Denim: Suitable for applicable denim buttonhole operations where the machine setup and needle system are appropriate for the fabric thickness.Polyester: Suitable for many woven polyester garments and uniforms.Suiting and formalwear: Useful for dress pants, suit jackets, formal shirts, and similar garments requiring accurately positioned buttonholes.Heavy-duty apparel: Can be used for suitable outerwear and heavier woven materials when the buttonhole machine is correctly configured for the fabric.For unusually thick, coated, stretch, or delicate materials, confirm that the machine setup, needle, thread, and clamping arrangement are appropriate before production.What Does the Presser Foot Do?The presser foot functions as part of the work-clamping system that keeps the garment positioned during buttonhole sewing.
