This is a Cross Frame Assembly Kit – Nitro Rollator
Main metal frame (black)
Tubular steel/aluminum construction.
Cross-brace design for strength and folding support.
Plastic housing or hinge locks (circled, left)
These are usually the pivot/locking sleeves that attach to the rollator frame arms, allowing the folding mechanism to function.
Rubber or plastic caps (middle row)
Likely end caps or bushings that fit into the frame to secure joints or reduce friction.
Hardware set (circled, bottom)
Includes bolts, screws, and washers—these secure the frame assembly to the main rollator structure.
The blue coating on threads indicates thread-locker to prevent loosening.
Drive euro-style walkers are built with three main principles. These are safety, comfort, and ease of storage for their users.
