We love it. I can't imagine anybody being able to get that off the tongue.

If you’re running a heavy utility trailer with a Curt, Ram, or etrailer cast 2-5/16-inch coupler, theft is a real concern these days more and more equipment trailers are being targeted when left parked on jobsites or lots. That’s where the ICON AL48DQ lock comes in. I like how it wraps over the coupler and makes it nearly impossible for someone to hook up and pull away quickly. This thing is nearly impossible to break into.



by:

If you’re pulling a livestock trailer with a Buyers Products coupler, hauling equipment on a Demco cast coupler, or running a heavy work trailer with a Wallace Forge setup, you already know those couplers are built for hard use. The ICON AL98DQ lock is made to match that same toughness. I was impressed by how heavy and solid it feels, it’s a solid block of cast steel with a design that makes grinders and saws practically useless. The unique half-moon key system is harder to pick and won’t freeze up, and the stainless cap keeps out mud and grit when your trailer’s sitting in a pasture or parked at the jobsite.



by:

I was impressed when I saw the ICON AL58DQ lock tested against standard tools, the cast steel body barely showed a mark, and the lock core design makes it really tough to tamper with. For a contractor hauling with a Buyers Products cast 2-inch coupler, the real risk isn’t just the trailer, it’s the skid steer, mini-excavator, or tools sitting on it, and I like that this lock was built to protect all of that. I love the weather-sealed cap because jobsite trailers sit out in the rain and dirt, and you need the lock to work every time you hook up. For work crews depending on a cast-style coupler, this lock makes the trailer a much harder target and keeps the expensive gear safe.



by:

I like the lock. It's large and heavy and looks like it would be difficult to cut off. The lockpicking lawyer had a similar one on his show and liked it. The only downside I can see is that someone could just unbolt my trailer coupler and swap it out. For me the lock is worth the money for the extra peace of mind.



by:

I’ve handled plenty of trailer locks that look strong but don’t hold up once an angle grinder hits them, so I wasn’t sure what to expect when Altor showed up with their ICON lock. Seeing it tested with real power tools changed my mind. The heavy cast steel and fin design force a grinder to fight through layer after layer before it ever gets close to the core. The lock face itself is built to spin under a drill bit, which just wears out the tool instead of the lock. I also like that the keys are made so duplicates can’t be cut at the corner hardware store, adding another layer of security. With its stainless body and sealed cap, it’s built to handle rain, dirt, and long storage outdoors. Overall, it feels like a serious step up from the average coupler lock, and when you think about the value of the trailer and everything sitting on it, investing in something this tough makes a lot of sense.



by:

I’ve seen plenty of trailer locks that look tough but could be taken off with an angle grinder in no time, so I’ll admit I was skeptical when Altor brought their ICON lock into the shop. After watching them actually go at it with power tools, I came away pretty impressed. The design uses thick cast steel with these raised fins, so even if you start grinding, you’re chewing through layers before you ever touch the core. They also built the lock face to spin if someone tries drilling, which just eats up the bit instead of the lock. On top of that, the keys are unique enough that you can’t just run to the hardware store and make extras. The stainless body and weather-sealed cap mean it holds up outside, which is huge for trailers that sit in lots or barns for months at a time. To me, it feels like a real step above the typical coupler lock and considering what you’ve got riding on your trailer, this is one of those cases where a tougher lock is worth it.



by:

I’ve come across plenty of trailer locks that look tough but are no match for an angle grinder. So when Altor brought their ICON lock into the shop, I wasn’t sure it would be much different. They proved me wrong. I watched them slice right through a well-known coupler lock with a grinder during their demo here. I will not call out the brand, but you can see it in my video. When it came time to test the ICON, the grinder barely made progress. Its solid cast steel build and finned design make it extremely difficult to reach the core. On top of that, the lock face spins when a drill bit hits it, which just wears down the tool instead of opening the lock. The keys are designed so they cannot be copied at the hardware store, and the stainless body with its weather-sealed cap keeps out rust, dirt, and moisture. After seeing it in action, I walked away convinced this lock is a real upgrade over the typical coupler locks, and if your trailer hauls valuable equipment, the added security makes a lot of sense.



by:

I was impressed by how solid the ICON AL38DQ lock feels when it’s in place. I love that it completely covers a Buyers Products or Wallace Forge cast 2-5/16-inch coupler, making it extremely tough for anyone to hook up and drive off. I like the weather-sealed cap too, because it keeps out dirt and water so the lock stays reliable even after sitting outside. The unique key system is designed so it’s harder to pick or copy, which puts it a step above standard coupler locks. For public works crews with service trailers full of tools, or really anyone hauling valuable equipment, this is a smart layer of security to keep the job moving. Just make sure you’ve got a Buyers or Wallace Forge cast coupler, since this lock is custom-fit — and if you run a different coupler style, ICON has plenty of other options to match.

See what our Experts say about this Altor Locks Trailer Tongue Lock

  • How Does ICON Trailer Coupler Lock Compare To Master Lock 379DAT?
    Derek, great question. The Master Lock # 379DAT works fine as a deterrent, but it can be defeated with basic tools. The ICON # AL63DQ takes it several steps further: it’s cast from a single block of hardened steel that’s as tough as any saw or drill bit, and it has an anti-drill lock face that just spins if you try to bore it out. In real tests, it shrugs off sawzalls, sledgehammers, and 5 inch angle grinders. This ICON lock is for couplers with a rather large, flat lip on the coupler....

  • Do Alter Icon Trailer Coupler Locks Add Tongue Weight To Trailer? How Much Do They Weigh?
    Olivia, each ICON weighs around 20lbs depending on the model. That heft is what makes them tough to tamper with. You’ll notice the weight when you lift it, but once installed on the coupler, it doesn’t affect anything. And it gets removed obviously when you tow the trailer, so it won't be adding tongue weight or anything like that (unless you throw it in a tool box at the front of the trailer or in the bed of your truck behind the rear axle - then it would count towards tongue weight). Do...

  • What Makes Alter ICON Trailer Coupler Locks Better Than Other Options?
    Pam, good question. The big differences are: patented radial fins that block grinders up to 5", one-piece hardened steel (not welded), an anti-drill face that spins drill bits, and a disc-detainer key that’s almost impossible to pick. It’s the only trailer lock lineup designed to resist power tools, not just hammers and bolt cutters. All in all, I'd spend the money on this bad boy if you have an expensive trailer with expensive equipment in it, or just want to make sure you have the best...

  • Can ICON AL38DQ Cast Coupler Lock Work On Rolled Lip Coupler ?
    Dale, the Cast Style Lock # AL38DQ is only for cast housings -if you’ve got a rolled-lip coupler, it may work, but it depends on what you mean exactly by rolled lip. Some cast couplers do have a little bit of a rolled lip, such as the bulldog # 3370091562. If your coupler lip is actually long and flat like # DM13203-52 then you'd instead want the Flat Lip Lock # AL63DQ. Do you know if your coupler is flat-fronted or more rounded?

  • Is The ICON Trailer Coupler Lock Hard To Install?
    Troy, some ICONs are snug because they’re precision-cast, but that’s part of their security. The # AL43DQ slides on pretty smoothly over the Hit-N-Hitch profile. The lock core uses a disc-detainer “outdoor profile” key that's designed to resist picking and survive in the elements. I've attached a demonstration video for you, but basically you'll unscrew (by hand) the metal cap covering the key hole, then unlock it and slide the pin down, place it on in your coupler and latch it in place,...

  • Coupler Lock That Fits Big Tex Equipment Trailer With 2-5/16" Bulldog Cast Coupler
    Greg, the # AL38DQ was designed for cast couplers just like yours. Bulldog and Buyers cast styles can be tricky to secure with universal locks, but the ICON hugs them tight. Since your trailer hauls heavy equipment, you’ll appreciate that this thing is made from a single piece of cast steel - hit it with a sledgehammer, you might knock a chip off, but it’s not coming off the trailer. Do you keep your Big Tex parked at jobsites overnight? For anyone with cast-style couplers, this model...

  • Do Icon Locks Hold Up To Job Site Theft On Big Tex Dump Trailer with Bulldog Coupler?
    Dave, yes - this is where the ICON # AL38DQ 2-5/16" cast style lock shines (also available in flat lip style 2-5/16" # AL63DQ). It’s made from a single piece of hardened steel, strong and bulky enough to shrug off sledgehammer hits, and the anti-drill face just spins a drill bit if you try to drill it out. Most “jobsite thefts” happen fast but ICON forces a thief to spend 20+ minutes with power tools, which usually sends them packing it up and moving to an easier target. There's also some...

  • Is ICON Trailer Coupler Locks For Flat Lip And Cast Couplers Universal Or Custom Fit?
    Alan, it comes down to coupler geometry, not universality in the traditional sense. The # AL63DQ covers the flat-lip coupler crowd which is common on travel trailers, while the # AL38DQ secures the cast-style coupler crowd which is more common on equipment trailers, but these are not concrete and can be found on others as well. Both are equally secure - they share the patented fins that block angle grinders and the anti-drill core. The flat lip has, well, a flatter more pronounced lip around...

  • Which Heavy Duty Lock For Equipment Trailer With Demco Cast 2-5/16" Coupler?
    Marcus, Demco makes both cast and flat-lip versions. If yours is cast (chunkier body, rounded nose), then the # AL38DQ is the match. The # AL63DQ is for flat lips - it likely wouldn't seat right on a cast. Both share the patented fins that stop 5" grinder wheels from getting in. Want to snap me a picture of your coupler? You can reply to this email if you'd like. But since you say you have demco cast coupler, the cast version is what I'd go with!

  • Should Trailer Dealers Order ICON Coupler Locks For Hit-N-Hitch Couplers Or Standard Couplers Onlyl?
    Tony, I'd say so! The Hit-N-Hitch style has grown in popularity on mid-size RV and livestock trailers. Generic locks usually don’t fit them right, so having the # AL43DQ gives you a true solution to point customers toward if they have that coupler. If you don't already carry the more common standard ones, I'd recommend ordering some of the flat-lip # AL63DQ and cast # AL38DQ models. Those will likely be more popular for the average customer, unless they have the specific Hit-N-Hitch coupler...
