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


just installed it. so far its good

well its still on the back of my trailer, works great
-- comment by: russell - 02/11/2014


My trailer has been out in the weather for a year and this product shows no sign of wear as tear.


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.


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.


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 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.


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!

  • How to Lock ROLA Dart Cargo Carrier 59550 to Trailer Hitch
    The ROLA Dart Cargo Carrier 59550 has a different thread count than any of the other carriers we have (I don't know why everyone avoids a universal solution) so to lock your carrier to your vehicle you'll need to use a cable lock like the Master Lock # 8218DPS and thread it through the carrier basket and the safety chain loops on your hitch receiver.

  • 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,...

  • How to Lock the Rhino Rack J-Style Kayak Carrier part # S512 to a Roof Rack
    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.

    You can get 2 of the DeadBolt cable locks, # e98891, keyed alike but not 2 of the Master Lock cable locks, # 8218DPS, keyed alike. To order 2 DeadBolt cable locks keyed alike simply select the keyed alike option from the drop down menu on the product page and then enter the number of locks needed into the quantity box.

  • 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....

  • 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.

  • 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.

  • Is There an Anti-Rattle Hitch Pin Lock for a Rola Dart Cargo Carrier
    I have an option for you but unfortunately the Rola 59550 cargo rack has a threaded anti rattle hitch pin which is going to be unique to that rack so the Threaded Anti-Rattle Hitch Pin Lock for etrailer Cargo Carriers # e99047 will not work. We have contacted the manufacturer about this issue in the past and you have two options for locking that Rola carrier to your hitch. The first and more unlikely option is to find a pad lock that is 1/8" thick to fit through the hole the cotter pin...

  • 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 lock,...

  • 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 lock...

    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 these...

  • Recommended Steel Mount For Spare Tire With 12 Inch Wheel And 5 On 4-1/2 Inch Bolt Pattern
    We do have a spare tire mount campatible with your Taskmaster 4.80-12, # AM30660, 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 x 1-3/16"...

  • 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...

  • Does the Swagman XTC-2 Two Bike Platform Bike Rack Have Locking Frame Hooks
    The frame hooks on the Swagman XTC-2, # S64670, do not have a locking mechanism, but you will be able to use Trailer Coupler Lock, # e98884, in the available holes on the hook housing. These locks will work unless you have two bikes with the same frame height. If so, you will be able to use a cable lock if you have one. If you need a cable lock, I recommend the Quantum 30 Steel Cable Lock by Master Lock, # 8218DPS. Just secure this lock from the bike to the safety chain loops on the hitch...

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...

  • Does Cable Lock Warranty Cover a Stolen Bike
    The warranty for the etrailer Cable Lock # e98891 is for a manufacturing failure of the product and doesn't cover something being stolen due to the lock or cable being "beaten" or damaged. For something a bit more beefy I recommend checking out the Master Lock Quantum 30 Armored Steel Cable Lock # 8218DPS (which has a 1-3/16" diameter cable) or the The Club Compact Utility Lock # WIUTL801. The warranty on theft would be the same for any lock though as given enough time, talent, and the...

  • Recommendation on a Bike Rack to Carry One Bike on a 2007 Kia Spectra5
    We carry both hitch and truck mounted bike racks that will work on your 2007 Kia Spectra 5. If you have a hitch on your Kia, then I recommend the Curt 2 Bike Rack for 1-1/4 and 2 Inch Hitches, # C18029. The bike rack can carry up to two bikes with a total weight of 90 lbs. The bike rack uses large anti-sway cradles to prevent bike-to bike contact. For a trunk mounted rack, I like the Saris Bones EX 2 Bike Carrier, # SAR83FR. This rack can carry up to two bikes with a weight of 35 lbs...

    If your transport is a one-time or occasional event you might consider a pair of basic rubber chocks like the # 337WC8127 for stabilization along with a cable lock to secure the vehicle by its axle. We offer the Master Lock Quantum 30 Armored Steel Cable Lock # 8218DPS that is 6-feet by 1-3/16-inches thick. This could wrap around an axle and be secured to a simple bolt on D-ring like # LRB1 (hardware is not included). This arrangement would allow the cable lock to serve other purposes when...

    Yes, the Hollywood Racks # HR37FR 3-Bike trunk rack is be a confirmed fit for your 2015 Toyota RAV4, and designed not to damage your rear spoiler. I have attached a link to the rack. If any of your bikes are Women's Step Through frames, or other alternatives, you need the Hollywood # HRBA-PRO Adapter Bar. This attaches between the handlebars and seat without damaging the bike. I have included a link to the product page and to a demonstration video. To protect your bikes and rack I recommend...

  • 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...

    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...

  • 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 some...

    I reached out to the biggest suppliers of trailer hitches, and neither Curt or Cequent (the maker of draw-tite, reese and hidden hitch) have a fit for your 2014 Mercedes Benz E350 Coupe. So, unfortunately I don't have a trailer hitch receiver that is a confirmed fit for your vehicle. If I can help you with a trunk mounted bike rack or a roof rack to meet your needs, please let me know and I'd be happy to make a recommendation.
