If you are refering to mounting gloves on the glove-ring, then this is known issue among Ultima DGS owners. While some have some sort of natural wizardry (
@MaxBottomtime and
@Deep South Divers) that permits them to easily use the stock o-rings to mount their gloves, the rest of us struggle tremendously with the stock glove retaining o-rings.
The solution is simple...toss the stock o-rings and pick up a pack of 341 x 70 durometer o-rings from Amazon or your favorite o-ring supplier.
The 341x 70 durometer o-rings make it super easy to mount gloves like the Showa 720/660/495/etc without any sacrifice in the o-rings' ability to retain the glove on your rings.
Here is a link to the o-rings I purchased.
