Keep your guitar secure with the confidence that comes from professional-grade hardware. The Jim Dunlop J1031N dual-design straplock system features hardened steel construction and a sophisticated groove-and-ball mechanism that provides complete 360-degree rotation whilst maintaining an unbreakable connection between your instrument and strap.
This robust system incorporates a four ball lock mechanism with wide flange button design, ensuring your strap stays exactly where it should be during performance. The recessed lock plunger adds an extra layer of security, whilst the interchangeable strap button design means you can use this system across multiple guitars in your collection.
Built to withstand extreme conditions, these strap retainers have been rigorously tested to 363 kilograms and simply won’t come loose when you need them most.
