- Designed for compatible 761-style industrial buttonhole machines.
- Suitable for shirts, blouses, trousers, uniforms, outerwear, knitted garments, and light-to-medium apparel fabrics.
- Direct replacement design for the compatible work-clamp arrangement.
- Supplied as 1 piece.
Use Cases
This work-clamp attachment is suitable for:
- Garment manufacturing factories
- Shirt and blouse production
- Trouser and dress-pant manufacturing
- Uniform production
- Outerwear manufacturing
- Boutique tailoring
- Professional tailor shops
- Industrial buttonhole-machine servicing
- Replacement of worn or damaged work-clamp components
Benefits
Firm Fabric Control
The work clamp holds garment layers securely during the buttonhole cycle, helping prevent unwanted fabric movement while the machine performs the stitching sequence.
Controlled Needle and Knife Clearance
The inner cutout provides working clearance around the needle and knife area, supporting consistent positioning during buttonhole formation.
Durable Industrial Construction
The hardened alloy-steel construction is designed to withstand repeated mechanical clamping and contact in industrial buttonhole production.
Smooth Fabric Contact
The polished base provides a smooth contact surface that helps minimize unnecessary catching or marking when working with finer garment materials.
Direct Replacement
The component is designed as a replacement for the compatible 761-style work-clamp arrangement, making it suitable when the existing attachment is worn or damaged.

How To Use
First, switch off the buttonhole machine and raise the work-clamp mechanism before removing the existing component.
Next, remove the existing work-clamp/presser-foot attachment and clean the mounting area.
Then, position the B1511-761-0A0 correctly on the compatible clamp-holder arrangement and secure it in the original mounting position.
Finally, move the clamp manually to check its movement and needle/knife clearance, then sew a test buttonhole on scrap fabric before returning the machine to production.
FAQs
Is B1511-761-0A0 compatible with Juki LBH-761?
Yes. B1511-761-0A0 is specified for the Juki LBH-761 industrial buttonhole machine. It is listed as a work-clamp/presser-foot component for the LBH-761 mechanism. Compare the existing component and part number before ordering to confirm the replacement configuration.
Does B1511-761-0A0 fit Juki LBH-762?
Yes. The supplied compatibility specification includes Juki LBH-762. Because the work-clamp mechanism contains several closely related components, matching the existing part number and physical configuration is recommended before replacement.
Does this part fit Jack 761-style machines?
It is specified for compatible Jack 761-style buttonhole machine variants. Clone machines can use similar mechanical layouts while having differences in individual components, so the machine model, existing work-clamp shape, mounting arrangement, and part number should be checked before purchase.
What is this component used for?
The component functions in the work-clamp/presser-foot area of an industrial buttonhole machine. Its primary job is to hold the garment material in position during the buttonhole cycle while providing the required working clearance around the needle and knife mechanism.
Can this be used for shirts and blouses?
Yes. It is suitable for garment materials used in shirts and blouses, as well as trousers, uniforms, outerwear, knitted garments, and other light-to-medium apparel applications. Proper machine adjustment remains important for maintaining clean buttonhole formation on different materials.
Can this work clamp be used for knitted fabrics?
Yes. The supplied fabric applications include knitted wear. The smooth base provides controlled contact with the garment while the clamp holds the material during the buttonhole sequence. Machine settings should still be matched to the thickness and stretch characteristics of the particular fabric.
What happens if the work clamp does not hold the fabric properly?
Insufficient or uneven clamping can allow the garment layers to move during the buttonhole cycle, which can affect buttonhole positioning and appearance. Check the work-clamp attachment, clamp-holder mechanism, spring condition, and machine adjustment before assuming that the presser foot itself is the only cause.
Is the B1511-761-0A0 supplied as a complete machine?
No. This listing is for 1 piece of the B1511-761-0A0 work-clamp/presser-foot component. It does not include the complete buttonhole machine or the entire work-clamp mechanism unless specifically stated in the product listing.
Does this product include the work clamp arm?
No. The product is supplied as the specified work-clamp/presser-foot attachment. The work-clamp arm, bracket, springs, holder, and other surrounding mechanism are separate machine components.
How do I install this replacement?
First, switch off the machine. Next, remove the existing component and clean the mounting area. Then, install the replacement in the same orientation and secure it correctly. Finally, manually check clamp movement and clearance before performing a test buttonhole.
Does the part require machine adjustment after installation?
A replacement should always be checked after installation. Confirm that the clamp moves correctly and that there is adequate clearance around the needle and knife. If the machine has been disturbed during replacement, further mechanical adjustment may be required before production sewing.
How can I confirm that I need this exact part?
Check your machine model and the number printed or referenced on your existing component. The supplied part number is B1511-761-0A0 / B15117610A0. Also compare the physical shape and mounting arrangement because the 761 buttonhole series contains several separate work-clamp components.
