Made from high-strength stainless steel, it resists rust and road wear so you can swap coupler sizes quickly at the trailer or yard. It’s intended to match the original GTW rating of the 2\" tow ball — it does not increase towing capacity — and fits a wide range of standard tow balls for dependable, temporary conversions.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I install the Clamshell adapter on my 2\" tow ball?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward and requires no tools beyond your hands. The two-piece clamshell design opens around the tow ball and clamps shut to form a secure 2-5\/16\" connection surface.

Use the tow ball and hitch manufacturer’s GTW rating as the governing limit; the Clamshell’s capacity matches typical 2\" ball ratings. This keeps towing safe and compliant when converting coupler size.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdapter equals the original 2\" tow ball’s GTW rating, not higher.\u003c\/li\u003e\n  \u003cli\u003eCheck vehicle, hitch, and tow ball ratings before towing heavy loads.\u003c\/li\u003e\n  \u003cli\u003eNot intended as a permanent method to bypass capacity requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and durability features does the Clamshell offer?\u003c\/h3\u003e\n\u003cp\u003eThe Weigh Safe Clamshell is crafted from high-strength stainless steel chosen for mechanical strength and long-term corrosion resistance.
