DMM Wallis Grommet

The DMM Wallis grommet is a small keeper that holds a carabiner in a set position on a device, eye, or sling. It stops the carabiner from rotating and ending up loaded across the gate, a common problem on climbing setups.

Why a keeper helps

Carabiners like to move. On a rope wrench tether, a lanyard eye, or a device attachment point, a loose carabiner can rotate until the load sits on the minor axis or against the gate, where it is much weaker. A keeper such as the Wallis grommet holds the carabiner in place so it stays oriented the right way.

It is a small part, but it makes your system more predictable and saves you from checking carabiner orientation every time you move. Fit one per connection where the carabiner should not move.

Fitting and checks

Small accessories like this are easy to overlook, but they change how your hardware sits and loads. Fit it the way the maker shows, then check that the carabiner gate still opens, closes, and locks freely and that nothing rubs on the rope.

Inspect it with the rest of your kit and replace it when it splits, stretches, or no longer holds the connector in position. It is an aid, not a strength component. Life-support gear must meet the applicable standard (ANSI Z133 and the manufacturer's instructions), be inspected before every climb, and be used only by trained climbers.
