Jim Dunlop Straploks – Black Oxide SLS1033BK

The Professional Standard for Instrument Security

For over 30 years, the Dunlop Straplok System has been the top choice for touring professionals. The SLS1033BK Dual Design features a specialized 360-degree groove-and-ball mechanism that allows your strap to rotate freely without catching or binding. Whether you’re moving across the stage or spinning your guitar, these locks provide the ultimate “set-and-forget” security.

Dual Design Versatility

The “Dual Design” button is what makes this system so popular. It features an extra-wide flange, meaning you can still use your guitar with a standard strap (without the locking attachment) in a pinch. The button acts just like a high-quality, oversized strap pin, providing more security than standard factory buttons even when the locking mechanism isn’t engaged.

Built for Extremes

Crafted from case-hardened steel skin, these strap retainers are built to survive a lifetime of abuse. Dunlop subjects every Straplok design to rigorous testing, and the SLS1033BK is rated to withstand a staggering 362 kg (800 lbs) of pull force before releasing. The recessed plunger design ensures that the lock won’t accidentally disengage if you bump it against your body.

GuitarBuddy Tip

This is our #1 recommendation for heavy guitars like Gibson Les Pauls or Fender Precision Basses. If you’ve ever had a strap slip off mid-song, you know the heart-stopping feeling of nearly dropping your guitar. Installing these takes five minutes and provides a lifetime of security!
