Draw-Tite Trailer Coupler Lock for 2-5/16 in Couplers - Gorilla Guard

In this review the Draw-Tite Gorilla Guard trailer coupler lock is assessed for owners who need a straightforward, heavy-duty deterrent against theft and tampering. The bottom line: this lock is best for trailer owners with a standard 2-5/16 in coupler who want a no-fuss security device that installs without tools and stands up to weather. The reviewer found the build durable and the fit snug when the coupler width and lip dimensions fall within the stated limits, making it a sensible security upgrade for stored or parked trailers.

Key Features

• Heavy-duty steel construction: The solid steel body provides robust resistance to casual tampering and the elements, increasing peace of mind when a trailer is stored outdoors.
• Universal fit for 2-5/16 in couplers: The design fits most 2-5/16 in trailer couplers and seals over the lip rim to block access to the hitch ball housing.
• Easy installation: No wrench or special tools are required, so one person can fit or remove the lock quickly when preparing a trailer for storage or transit.
• Weather protection: Built to withstand harsh weather exposure, the lock is suitable for long-term outdoor use without rapid corrosion when maintained.
• Includes two keys: Two keys are supplied so there is a spare available for a second user or as a backup.

Who It's For

This lock is aimed at recreational and light commercial trailer owners who use a 2-5/16 in coupler and need a simple, physical deterrent against theft while parked or in storage. It suits those who prefer a low-maintenance device that mounts without tools and can tolerate a heavier, bulkier lock for added security.

Those who should look elsewhere include owners with coupler widths over 4-1/8 in or coupler lip heights greater than 5/16 in, since the lock will not fit correctly. Similarly, buyers requiring an electronic or alarmed solution should consider alternative products that offer active alerts.

Pros & Cons

• Universally sized to work with most standard 2-5/16 in hitch balls, simplifying replacement or shared use between trailers.

• Includes two keys so a spare is immediately available.

Cons

• Not suitable for couplers that exceed the specified maximum width of 4-1/8 in or lip height of 5/16 in, limiting compatibility in some applications.
