Covered rims are most indicated when the user requires what for hand contact with rims?

• A. Eliminates need for assist.
• B. Requires assist for adequate grip or friction when hands contact rims.
• C. Improves friction without contact.
• D. Prevents any hand contact.

Answer: (B)

Covered rims are used to make the hand-rim interface grip safer and more controllable during propulsion. They’re most indicated when the user needs more friction at the point surfaces contact the rims—for example, when grip is weak or unreliable and assistance would otherwise be needed to achieve a secure hold. The covering increases surface area and texture, reducing slip and giving the user a firmer, more stable push. It doesn’t aim to eliminate all assistance or to function without any contact, and it wouldn’t make friction occur without the hand actually contacting the rim.
