Video Transcript for Master Lock Quantum Steel Cable Lock Review

Today we're going to take a look at Master Lock Quantum 30 Armored Steel 6 feet long cable lock, part number 8218DPS. This hardened steel cable lock easily secures one or more items and features a strong, corrosion resistant construction, the heavy duty cable lock, deters theft, and the braided steel cable resists cutting and sawing. The hardened steel sleeve over the braided cable provides additional security. See our 6 foot long cable lock here which has a nice lock cylinder that the cable secures nicely into. It is vinyl coated so it's going to protect any surface that you're going to be mounting it to such as a generator on a trailer or a motorcycle wheel here as we're going to show. It has an extra steel braided construction on the inside and it can articulate so you're going to be able to wrap it around whatever you need. It does have four keys.

You go ahead and stick the key in there, rotate it, and it will unlock. For this application, we're be securing our motorcycle here and we'll deter theft since the cable lock will go through the front wheel and it won't allow it to turn. Go ahead, feed it through, up around the forks, back into itself. Lock it. Now your wheel is secured around your forks. It's not going to allow your wheel to turn.

This nice vinyl coating protects your paint when it's sitting on your fender. The nice thing about this cable lock is it does articulate so you can go ahead and wrap it up, store it in one of your storage compartments on your bike if you have saddlebags. Or if you're storing it in a trailer, you can go ahead and just put it in your front compartment of your trailer or even throw it in your truck, depending on the application you're using it for. That'll do it for our look at the Master Lock Quantum 30 Armored Steel Cable Lock, part number 8218DPS. .

So far this lock has been exactly what I needed, the durability has been excellent the locking feature has been effortless and flexibility is perfect when storing as well as locking around different objects. I can't be more happy with the Master Lock Quantum 30 cable

- 8218DPS

Overall this is a very good product. The only reason for not giving five stars is that the lock mechanism is finicky and can be a pain in the neck sometimes.

- 8218DPS

I am VERY pleased with this purchase -- this lock will serve me well for years to come, and the price was a bargain!! Thank you!!

Excellent product!

- 8218DPS

This is still working very well. We started out using it on our fifth-wheel hitch and now use it to lock our bikes. It is very flexible, yet still very secure.

- 8218DPS

I purchased this lock to secure my ATV to the trailer while at the motel etc. The cable is substantially bigger than most giving added security and peace of mind, it appears well made.

- 8218DPS

Just received our Masterlock Quantum 30 and cannot get it open. Looks like either they sent the wrong keys or the lock mechanism is defective. Very Frustrating.

I use this to lock my tandom trailer wheels together when parked. Works great.

  • How to Lock Generator to Stromberg Carlson Bunk Platform Adapter
    Easiest way to lock a generator to the Stromberg Bunk carrier part # CC-255 would be to run a cable lock like the part # 8218DPS around the base of the bunk and then through the handles of the generator.

  • Can Go Power Portable Solar Panel System be Locked to Camper Trailer to Deter Theft
    That's an interesting question and there is an option to add some security to the Go Power Portable Solar System with Digital Solar Controller # 34282730. What you an do is use a cable lock to secure one of the legs of the solar panels to, for example, a leg of one of the jacks on your camper. Most theft is really based on opportunity so if someone sees a heavy-duty cable lock around the solar panels, they are going to keep right on going. I strongly recommend a Master Lock cable...

  • Locking Options for Malone MicroSport MPG462G2 Trailer for 4 Kayaks
    The trailer doesn't include locks, which is typical, as trailers don't usually include them. The good news is that there are tons of locking options available, and usually using more than one locking option at a time will deter all but the most determined thief. The Malone MicroSport # MPG462G2 trailer uses a typical 2 inch channel tongue coupler. At a minimum, I'd use a coupler latch lock like part # e98890. I even use these while towing, to prevent the latch from coming open or...

  • Will a Cable Lock Keep My Bikes Safe or Can Someone Just Cut It Off?
    Honestly, it would be pretty easy for someone with bolt cutters to cut through the cable lock you mentioned, # e98891. Locks in general are not a guarantee against theft, but a deterrent. If someone is determined to take your personal belongings, a lock is not going to stop them. But, if you have entwined a cable lock through your bikes, a thief will most likely move on to an easier target rather than fiddle with unwrapping your cable lock. If you are looking for a sturdy cable lock,...

    The only way to lock the Rhino Rack J-Style Kayak Carrier part # S512 to your roof rack would be if you used a cable lock like the part # 8218DPS. You would have to route the cable through the rack and around the crossbars.

  • Bike Carriers for Recumbent Bike and Recumbent Trike Carried on Yakima Rack and Roll Trailer
    The total weight capacity of the Yakima 66-Inch Rack and Roll Trailer # Y08106 is 250-lbs and this is enough for the combined weight of your various bikes and carriers. The I.C.E. VTX recumbent trike has a base weight of 29-lbs and up, depending on options. The Bacchetta Strada weighs 28-lbs without pedals. The Burley Tail Wagon pet trailer weighs 23-1/2-lbs. So in all, the three "vehicles" weigh about 80-lbs total, well within the trailer capacity. For the Strada I suggest the Yakima...

  • Available Locks for Kuat Sherpa Hitch Bike Rack and Rola Cargo carrier
    The Rola Dart hitch-mount cargo carrier # 59550 comes with a threaded non-locking hitch pin that steadies the carrier in your hitch but does not lock it. For this cargo carrier no locking pin is available, but you can easily secure the carrier to your hitch simply by installing a cable lock that can be routed through the carrier and the safety chain loops on your hitch. We have many such cable locks, such as 10-foot # e98891 and 6-foot armored cable # 8218DPS which uses keys and # 8122D...

  • Recommended Cable Lock to Deter Theft of a Honda 2200 Generator on Rear of Travel Trailer
    The 10' Long Cable Lock # e98891 is a versatile cable lock to secure your Honda 2200 Generator to your travel trailer. There isn't a cable lock that can deter a motivated thief, but the Master Lock Quantum 30 Armored Steel Cable Lock - 6' Long x 1-3/16" Diameter # 8218DPS is my recommendation to make them reconsider their choices. I'd also route the cable through the safety chain loop of the hitch.

  • Motorhome Scooter Carrier for Class C RV to Carry 474-lb Suzuki Burgman 400 Scooter
    Your Suzuki Burgman scooter has a substantial curb weight of 474-lbs. This means you will need a hitch-mount scooter carrier such as the motorhome-approved Ultra-Fab Carrier # UF48-979033 which is rated for up to 500-lbs. You'll also want to check the safety sticker on your RV hitch to ensure that the hitch itself is rated with enough capacity for the combined weight of the scooter and the 50-lb carrier. Your hitch must be rated for at least 500-lbs of total tongue weight. Since scooters...

  • Availability of a 3/4-Inch Thick 10-Foot Cable Lock
    The majority of cable locks we offer are substantially smaller in diameter than the 3/4-inch size you are looking for. We do offer various lengths of 3/8-inch diameter cables (some on their own and others with locks) such as the Master Lock # 8256DAT. This is the largest diameter we offer in 8-foot or greater length. We also offer the Master Lock Quantum 30 Armored Steel Cable Lock # 8218DPS which is a substantial 1-3/16-inches thick but this part is only 6-feet in length. Perhaps two units...

We have the 10-foot Deadbolt # e98891 that you referenced which has a 5/16-inch cable, the 15-foot Master Lock cable (padlock not included) # 72DPF which has a 3/8-inch diameter cable and the super heavy duty Master Lock Quantum # 8218DPS which is 6-feet long and a beefy 1-3/16-inches in diameter! You can see all our able locks on the linked page. I recommend you use the heaviest cable that is long enough to reach between your generator's...

  • Locking Hitch Pin Recommendation for 23x56 Rola Dart Cargo Carrier # 59550
    The 23x56 Rola Dart Cargo Carrier, # 59550, has a solid shank with a threaded hitch pin hole for use with it's anti-rattle hitch pin. A locking hitch pin is not available for use with this style of hitch pin hole. In order to secure the carrier to your vehicle, I recommend using a locking cable like the Master Lock Quantum 30 Armored Steel Cable Lock, # 8218DPS. This cable can wrap around the carrier and your hitch to deter theft.

  • Lock Options for SportRack Upshift Deluxe Roof-Rack-Mount Bike Carrier
    The SportRack Upshift Deluxe roof-rack-mount bike carrier does not have a built-in lock mechanism to secure it to your roof rack, but it does have a lock for your loaded bike. If you prefer a bike carrier with both bike and rack locks you can use the linked page to see all options. You also have the option of adding a cable lock like 15-foot # FCLK150100, 10-foot # e98891 or 6-foot # 8218DPS to the Upshift Deluxe which you could simply run through the bike wheels and frame to secure...

  • Can I Open Trunk On 2016 Subaru Impreza With Trunk Mount Bike Rack
    The Thule Passage 2 Bike Carrier part # TH910XT uses the hatch of the 2016 Subaru Impreza Sedan to attach to the vehicle so you would not be able to open the hatch with the bike rack on the vehicle. Once you open the trunk the metal hooks are not going to have a solid surface to grip on and it could lead to the bike rack falling off and the extra weight from the bike rack could also damage the trunk's lid if you open it. If rear cargo access is important to you while you are out and...

  • Method to Secure 2012 Scion iQ in Toy Hauler Trailer
    The MaxxTow Adjustable Wheel Chock # MT70075 that you referenced does bolt to the trailer floor with included hardware but this is intended for motorcycles and is not suitable for your Scion. Also, you would need to go through the process of unbolting it each time its used (meaning crawling under the trailer). The same is true for their Self-Locking Wheel Chock # MT70271. If your transport is a one-time or occasional event you might instead consider a pair of basic rubber chocks like...

    We do have a spare tire mount campatible with your Taskmaster 4.80-12, # TTWAS12B45WSHP, spare tire. I recommend the Fulton Hi-Mount Spare Tire Carrier, # FSTC1000301. This mount will bolt onto your 5x8 trailer to accomodate that full size spare. It will fit trailer frames up to 3 inches wide and 4 inches high. This mount will give you plenty of ground clearance and will not corrode with its zinc plating. I also recommend the Master Lock Quantum 30 Armored Steel Cable Lock - 6' Long...

  • Falcon 2 Tow Bar Keeps Falling Out of Stored and Latched Position
    It sounds like there is problem with the storage latch on your tow bar. I recommend making sure all the nuts and bolts are tightened because if something has gotten loose over time then that could be the problem. If you think there is a problem with the latch itself we have replacements; # RMB001353. There isn't a special device made to hold up the tow bar arms (other than its own latch) so the best solution would be to use a cable lock such as # 8218DPS. The benefit of using a cable...

    For use on both your 2012 Honda Pilot and your 2016 Kia Sorento, the Yakima KingJoe 3 Bike Trunk Mounted Rack is a confirmed fit but is no longer available. I recommend the very similar Yakima HangOut 3 Bike Rack - Trunk Mount - Adjustable Arms # Y02638. It has a 6-strap system that holds the rack securely in place. It is easy to install with quick-trigger hub. It also has StableCradle that holds bikes firmly in place. I also recommend the Hollywood Racks Over-the-Top 3 Bike Rack...

  • Can the Rola Roof Mount Cargo Basket Be Locked to the Crossbars
    The best way to secure the Rola cargo basket # 59504 to the crossbars would be to use a cable lock like # 8218DPS or a locking strap like # LS901. Rola does not make locks specifically for the cargo basket. If it were me, I would go with the strap because it is shorter and there are no keys to worry about. I have linked a video review of the locking strap for you.

  • What Folding J-Style Carrier do You Recommend for a 95-Pound Kayak on a 2013 Buick Encore?
    I have a solution for you. Unfortunately, the only folding j-style carrier that can accommodate your 95-pound kayak on your 2013 Buick Encore is the Rhino-Rack J-Style Kayak Carrier - Folding - Universal Mount # S512. The Rhino-Rack J-Style Folding carrier is compatible with your Rhino-Rack Vortex Aero crossbars and comes pre-assembled for easy installation on your roof rack. The only downside to the Rhino-Rack J-Style Carrier is that it does not have the capability to house lock cores....
