Rogue’s USA Aluminum collars use hinged nylon levers and internal rubber linings to clamp Olympic bar sleeves. The supplied pair weighs half a pound, with each collar occupying 1.5 inches of sleeve.
The lever closure is the reason to choose them over spring clips. They complete an Olympic barbell order without adding much weight or sleeve width.
The drawbackStandard Olympic sleeves are the intended fit. Specialty bars and loadable handles can use other diameters, so those dimensions decide whether this pair is suitable.
PRIME’s RO-T8 pair combines palm-shaped supports with swivelling cable connections. The handles work independently on cable exercises or with the separately sold RO-T8 Short Bar.
The RO-T8 Short Bar connects two compatible handles to one cable, with attachment spacing from 9 to 18 inches in one-inch steps. This purchase supplies the bar alone.
