Looking for a way to not only fasten your products in style, but also truly secure them mechanically? This unique roller buckle features a practical roller for smooth tightening and a special pin with an eyelet. This allows you to thread a padlock or security cable through it, locking the strap firmly in the desired position.

  • Security on the go: An essential solution for motorcycle bags, backpacks, or travel luggage, where a lock through the pin eye helps protect contents from opportunistic theft.
  • For specialized applications: Thanks to its ability to be securely locked, this buckle is an ideal choice for premium BDSM collars and harnesses, where elegance meets functionality.
  • High durability: The stainless steel version in particular stands out with exceptional strength, offering a breaking load of up to 150 kg.
  • Recommended tools: For precise hole preparation in the strap, we recommend using the oval punch #3778-09.

Expert's opinion

Craft isn't just about feel – it's about understanding the material and the process. If it works in my workshop, it'll work in yours.

This buckle is a technical standout. The eye on the pin works as an excellent mechanical safety feature – even without a lock, the pin sits much more securely in the strap hole thanks to the eye. Its full potential, however, comes into play when paired with a small padlock.

Keep a few details in mind during production:

To ensure the pin eye passes smoothly through the strap, we recommend using an oval punch. It’s the ideal choice for easy fastening without unnecessarily stretching the material around the pin.

Also note that once fastened, the entire eye of the pin must extend above the material so a lock can be threaded through it. We recommend leather with a thickness of around 3 to 3.5 mm. If the material is too thick, the eye will sit too deep and you won’t be able to pass the lock through.

For the eye with an inner diameter of 4.8 mm, choose a padlock with a shackle thickness of up to 4 to 4.5 mm to ensure sufficient clearance.
