Vac-U-Lock® Accessories – Knuckle Up

The Knuckle Up is a handheld Vac-U-Lock grip designed for users who want direct, precise control during use. The brass knuckle-inspired frame fits naturally between the fingers — four finger loops distribute grip evenly across the hand, eliminating wrist strain and giving you a stable, locked hold at any angle.

Where suction cup bases work best on flat surfaces, the Knuckle Up works best in your hand. It converts any Vac-U-Lock compatible dildo into a handheld toy with a grip that does not slip, shift, or require readjusting mid-use. The compact frame adds no significant length — the dildo sits directly above the grip, keeping the experience as natural as possible.

Compatible with all RealCock Toys dildos and any Vac-U-Lock® attachment worldwide.
