Best Puck Lock for Trailer Reviews

1). Trimax THP3XL Hockey Puck Trailer lock

If people call this the best puck lock for trailer, it is partially because TRIMAX has a reputation for making high-quality products with innovative designs. Their internal shackle door lock is the perfect counter to bolt cutters.

The re-keyable lock hides the shackle. This will frustrate criminals who favor bolt cutters because the lock doesn’t offer apparent targets for them to cut. Not only is the lock easy to use, but the body is thick, solid, and resistant to extreme weather.

In other words, you can use the lock within any outdoor setting that suits you. It works on trailers, gates, and even trucks. The heavy-duty security hasps can take quite a bit of punishment before they give way.

2). Trimax THP2XL Keyed Alike Trailer Lock

Trimax has spent the last two decades making high-quality security locks for various industries. People use their products on trailers, towing trucks, RVs, bicycles, and more.

Therefore, it won’t surprise you to learn that their THP2XL trailer lock is one of the better locks on the market, weighing just 2.2 pounds. The silver lock was made from Alloy Steel. It has enlarged opening covers and strong hasps that won’t surrender in the face of severe punishment.

The shackle is the weakest part of most locks. Once you break or cut it, you can remove the lock. But that concern is non-existent here because the lock doesn’t have a shackle. To be more specific, the shackle is hidden.

Criminals cannot access it, which means that they have nothing to cut. This tells you that your trailer is safe from bolt cutters and saws. Without the shackle, the only other option is to cut through the body of the lock.

But that isn’t a feasible option because the lock has a thick, solid steel body. Therefore, you can trust this product to resist intruders.

3). Proven Industries Puck Trailer Lock 400XL

This US-made lock uses Aircraft Grade 6061 Solid Aluminum. The body is resistant to corrosion, and intruders cannot break it with standard tools like bolt cutters.

Each lock comes with two identical keys. The cylinder is resistant to conventional lock picking tactics. Before you ask, the shackle is fully shielded. Criminals will have a difficult time accessing or prying it open. The manufacturer took every feasible measure to make the lock a nightmare for intruders.

The openings are 1/34th of an inch long and 7/8th of an inch high. The depth is 1 ¼ of an inch. The weight is 3.29 pounds.

4). Proven Industries Lock model 2516 for Trailer

This is probably the strangest-looking lock you have ever seen. The manufacturer settled on this design after investing 200 hours into research and development.

The trailer lock fits a specific frame coupler. If you visit their manufacturer’s website, you will see pictures of the three frame couplers compatible with the lock. If you cannot find your frame coupler on the website, they encourage you to reach out to them.

They have a variety of locks that fit different coupler designs. You don’t have to limit your options to this one. The manufacturer is confident that the other locks in their catalog will match your needs just as efficiently.

If their lock can accommodate your coupler, don’t let the design fool you. It is surprisingly easy to install and secure. Boasting ¼-inch All Steel Construction and a black powder coat finish, the lock has defenses against bolt cutters. In fact, the lock is bolt cutter proof. It weighs 10 pounds.

5). NU-SET 2-7/8 Inch Hockey Puck Padlock

This heavy-duty lock can be trusted to stand the test of time because the manufacturer used chrome to make the product rustproof. Even in an outdoor setting, the lock will last a while.

The steel shackle is hidden, making it more difficult to pry open or break with bolt cutters. The 2-7/8-inch-wide steel case repels violent attacks. The 6-pin tumbler cylinder is the perfect answer to lockpicks. Even though it looks incredibly thick, the lock is just 2.14 pounds.

Best Puck Lock For Trailer Buying Guide

How do you find the best puck lock for trailer? You can’t just make a random selection. Use these factors to guide your decision:

1). Consider Puck Lock Material

What materials did the manufacturer use? The materials determine the strength and durability of the lock. Many people flock to locks made from low-cost materials because they are inexpensive. But a cheap lock is pointless. It creates the illusion of security, but you can’t trust the lock to keep your valuables safe.

Look for locks made from stainless steel and other high-quality materials. If you have no other choice, aim for zinc. Zinc is not the best, but it is better than many cheaper alternatives.

2). Brand

The brand matters. Some companies have a reputation for making high-quality trailer locks. Others make junk. Listen to the public. What are people saying about your brand of choice?

Do they like the locks they have purchased from the company in the past? Do those locks last? What sorts of complaints have they raised? The public will not buy trailer locks from an untrustworthy brand. Where trailer locks are concerned, you should follow the masses.

3). Ease of Use

Naturally, you must pay close attention to the security considerations. For instance, how thick is the shackle? How much of the shackle is exposed? Can you pick the lock?

These questions are important. However, they are not as relevant as the ease of use. No one will use a trailer lock that is difficult to install, no matter how solid and secure it is.

Try to find a lock that balances all these factors, that is, a thick item with a solid construction that is also easy to install and use.


Finding the Best Puck Lock For Trailer is not easy because the demand for decent Puck Locks is high, so manufacturers have flooded the market with trailer locks.

Unfortunately, most of them are substandard. But that is why this guide was created. Rather than making a blind selection and wasting good money on a poorly designed lock, use one of the options listed above to give your trailer the protection it deserves.
