The Curt 20001 Trailer Ball Wrench is designed specifically for installing and removing trailer ball nuts. The dual-ended design fits the two most common hitch ball nut sizes, providing the leverage needed to properly torque your trailer ball.

• Two wrench sizes: 1-1/8" and 1-1/2" openings
• Fits hitch balls with 3/4" or 1" diameter shanks
• 15-1/2" length provides excellent leverage
• 6-point hex design for solid grip on nuts
• Forged, hardened steel with chrome plating
• Prevents rounding of trailer ball nuts

Tip: Use the 1-1/8" end for 3/4" shank balls and the 1-1/2" end for 1" shank balls.
