Features to know about

Ultimate Trailer Security: Wraparound Cam Door Latch

If you've been searching for a reliable way to secure your trailer doors, whether for a side or rear application, look no further. The cam-action feature—or the "Cam Door Latch"—is designed to provide peace of mind by preventing tampering during your travels. With its narrow, wraparound keepers, this latch ensures a firm lock, letting you cruise with confidence knowing your cargo is safe.

Durability on the Go: Zinc-Plated Steel Construction

When exposed to the elements, inferior materials can rust and weaken, but this door latch has you covered with sturdy zinc-plated steel construction. This makes it tough enough to handle rain, sleet, or snow, and provides long-lasting durability through many adventures. It’s built to withstand the rigors of road life, keeping your gear secure mile after mile.

Smooth and Easy Operation: Double-Action Handle

Road vibrations can often jar trailer doors, but with the double-action handle, this latch goes above and beyond in ensuring security. It's designed to make latching and unlatching smooth and simple, so you can secure your doors with minimal effort. Plus, it features a black vinyl covering for a comfortable grip.

Customize Your Fit: Versatile and Reversible Design

Whether your trailer requires a left-hand or right-hand door application, this cam-action lock adapts easily to meet your needs. Its reversible hinge system allows for a tailored fit to your particular setup, so you don’t have to worry about compatibility issues—it's customized convenience at its best!

Perfect for DIY Projects: Simple Bolt-On Installation

Installing new hardware on your trailer can be daunting, but this latch makes it straightforward with its simple bolt-on installation. And while the necessary mounting hardware isn't included, sourcing what you need locally means you can tackle this project with minimal fuss. Just grab a 3/4-inch diameter pipe to complete your setup.

Precision Fit and Finish: Spec-Packed Design

For those who value specifics, this latch has exact dimensions to ensure everything fits perfectly. The hasp is 5-1/8 inches tall x 1 inch wide, while the keeper is 5-1/8 inches long x 1-3/8 inches wide, keeping things consistent and providing a precise, tailor-made fit for various trailers and small trucks.

  • Recommended Handle Latch Kit for Barn Door on Dump Trailer
    For the barn door on your dump trailer, I recommend looking at the Cam-Action Lockable Door Latch Kit # 383200. This is a nice steel cam-action door latch with a 1 inch wide hasp that can be installed flush on doors with a 3/4 inch offset. It features a bridge-type hasp that will help to prevent accidental opening and secures a safe latching action. This will use a 3/4 inch diameter pipe that you can source from a local hardware store. This will be a simple bolt-on installation. I have...

  • Recommendation for Making a 45 Inch Cam Door Latch
    I have a solution for you, but it will require you to supply your own 45 inch long 3/4 inch inside diameter pipe. You will want to get the Universal Cam-Door Lock for Enclosed Trailers # 383200. Some welding is required for installation of this kit. I would use regular steel because it is easier to weld then galvanized materials.

  • How Do the Cam Ends of the Redline Universal Cam-Door Lock # 383200 Install
    Are you sure the pipe you have has an inner diameter of 3/4 of an inch? The cam ends of the Redline Universal Cam-Door Lock, # 383200 should fit tight into the pipe. However, since you already welded the handle to your pipe you could weld the cam ends so the pipe. You will want to make sure the outer diameter of the pipe isn't bigger than 1-1/8 inches.

  • Do Cams Need to be Welded to 3/4" Pipe to Install the Polar Cam-Action Lockable Door Latch Kit
    Yes, the cams (as well as the handle) need to be welded to a 34" Schedule 40 Plumbers Pipe with a 1.06" outer diameter for proper installation of the Cam-Action Lockable Door Latch Kit # 383200. To keep the pipe from dropping down when the door is opened you will just need to install one of the retainers just below the handle as you can see from the attached photo a customer sent in.

  • Universal Cam-Door Lock Recommendation for Toy Hauler that the Door Does not Close all the Way
    I believe I know what is happening. It sounds like your door latches are at the middle of your door which leaves the top of the door slightly open. You could use a Universal Cam-Door Lock for Enclosed Trailers # like what you referenced. I would run it across the top lip of your trailer ramp so that it will secure the top of the door as well. Depending on the setup you might consider leaving your current latches and then install a # 383200 as well. Or, you could move your current latches...

  • Recommended 33-1/4 Inch Cam-Door Lock for Enclosed Trailer

The Universal cam-door lock with 1 inch keeper # 383200 will allow you to create a bar lock assembly of 33-1/4 inches. With this item you supply the 3/4 inch inside diameter pipe to make a custom door lock. Some welding will be required for installation of this kit. If you needed one with a larger keeper, I have linked all the cam-door locks to this page for you to check out. I have...

  • Replacement Rear Cam Door Lock Recommendation for a 2012 Voltage 3900
    If you have a bar style door like the part # 3057-55 that you referenced on your trailer you could pretty easily replace it with the # 3057-55. The hinges may match up but we don't know that for sure. You can check out the picture I attached that has all of the dimensions of the lock for you to check out as well. If you wanted to provide your own pipe so that the lock you get matches the same length as what you have you could use the part # 383200 instead. You would need a pipe with a...

  • Availability of a 55 inch Cam Lock Door Lock for Enclosed Trailers
    You would need to use the Universal Cam-Door Lock for Enclosed Trailers, item # 383200, to create a bar lock assembly of 55 inches. With this item you supply the 3/4 inch inside diameter pipe to make a custom door lock. Some welding is required for installation of this kit. Due to shipping restraints we do not have a Side-Door Bar Lock Assembly longer than 36 inches at this time.

  • Does Pipe Get Welded to Cams on Universal Cam-Door Lock for Enclosed Trailers
    The cams for the end of the pipe for cam-door lock # 383200 basically are compression fit into the end of the pipe you use (not included). They can be tacked if need be but welding is not required.

    Cam-Action Lockable Door Latch Kit w/ Narrow Hasp for Small Enclosed Trailers - Zinc-Plated Steel # 383200 will have the lug for the cam driven in and secured with a weld bead. You can alternately use a fastener as you described, but for the best function welding is recommended.

This will allow you to customize your length using a 3/4 inch pipe which is not included. This style of lock normally doesn't need to be within an inch, so I also have attached another style of lock that may be what you are looking for. It is the Cam-Action Lockable Door Latch Kit w/ Narrow Hasp for Small Enclosed Trailers - Zinc-Plated Steel # 383200. This...

  • Can a Universal Cam-Door Lock for Enclosed Trailers be Used in the Horizontal Position
    It is possible to use the cam-door lock, # 383200, horizontally but it would need to be placed up higher than the midway point to reduce the amount of stress on it when the door is closed. Take a look at the picture I have included that shows this type of set up. For a lock you could use # BLDL-80.

  • Does a 3/4 Inch Pipe Get Welded to the Upper and Lower Brackets of Universal Cam-Door Lock
    No, you wouldn't weld the bar to the mounting brackets for the universal cam-door lock, # 383200. The bar needs to be able to rotate and welding it would prevent it from moving. Only the handle would be welded to the pipe. I have included a link to a video review of this part for you.

  • Door Lock Recommendation for a Ramp Style Trailer Door
    If you have a ramp style door that swings down and becomes a ramp what I recommend you do is purchase 2 separate 36 inch Lock Side-Door Bar Lock Assemblies, part # 305736, and mount one on either side of your door. This way you will get a handle and hinge on either side of the door like you want.

  • Cam Door Lock For Use On Workshop Doors
    A cam-door lock will work great for what you are building. The 55" Lock Side-Door Bar Lock Assembly, # 3057-55, will only give you a portion of the assembly you need. I recommend the Universal Cam-Door Lock for Enclosed Trailers - 1" Keeper, # 383200, for your application. This will give you everything you need other than the 3/4" inner diameter pipe. That will allow you to customize the locations for the cams to best fit your doors. These locks do not come with the bolts to secure...

I instead recommend looking at the Polar Cam-Action Lockable Door Latch Kit # 383200. This steel cam-action door latch is a more universal design that does not include the 3/4 inch inner diameter pipe. This will allow you to use this kit with a pipe that features a length of your choice, as...
