I wanted additional strap loops for my new Ortlieb Dry-Pack to keep the straps nicely organized.

The ones that came with the bag slide around freely and I keep them close to the buckle. This model includes a small bump in one ring to lock onto the strap at a specific position and keep the dangling end of the strap out of the way.

The rings are 20 × 2.5 mm rectangles, with 3.5 mm circular bumps.
Sliding it onto the strap the first time is pretty tight due to the bump but then it stays nicely in place with some wiggle room on the hole.
