Video Transcript for Master Lock Solid Body Padlock Review

Today we'll be taking a look at the Master Lock covered solid body padlock. That's part number 131D. This is a really nice lock. It will help guard your gear against any theft. It's got a really nice hardened steel padlock to it. The lock has got a nice scratch resistant vinyl coating.

It also offers a 4-pin tumbler security to deter any lock picking. It also includes a convenient color-coded key so as you see here it matches with the actual padlock itself. Also comes with two keys so either if you misplace one or if you are giving it to a spouse or a significant other, they'll be able to have that too. It just pops right open like that as you can see. It is also corrosion resistant. It's got this nice hardened steel construction which insures strength and durability. It's kind of a nice stylish thing that will go with any of your things such as a bag at the airport, or locking up your fence, going to the gym and taking this and locking up your gym locker.

Today we're actually going to show you an application on a trailer. We're going to go ahead and put these on some wheel chocks so let's go ahead and grab those. We're here at our trailer. We've got our wheel chock in place already. We have these in place just to make sure that the trailer doesn't maybe roll down the hill or maybe if someone might roll off of there without you knowing. We're going to go ahead and take our Master Lock slide it into place and pop it on just like we would any regular lock that we have.

It is now in place and as you can see with that now in place, we won't be able to pull up on this and with one of our two keys just slide it into place whenever we're ready to move our wheel chocks. Just like a lock on your luggage, it will pop right off. That will complete today's look at our Master Lock Covered Solid Black Padlock, part number 131D. .

Ask the Experts about this Master Lock Padlocks


  • Recommended Hasp And Lock For Enclosed Trailer That Deters Theft
  • The closest we have to the dimensions you mentioned is part # PLR158-102-A which measures 4-inches hole to hole. If that will not work for you and you have to drill a new hole for the hasp I recommend part # PLR158-102-SS. This measures 3-3/4 inches center to center for the mounting holes. I do have an alternative for you. I recommend a lock like part # 720DPF. The mounting hardware is hidden under the covers and it is difficult to pry off. It is made of hardened steel and uses a padlock...

  • Hitch Lock Recommendation for a BikeWing Bike Rack on a 2017 Chevy Bolt EV
  • The drawbar would only be used if you were towing a trailer and the 2017 Chevy Bolt EV is not rated for towing so you would not need the drawbar. I checked your order notes and it looks like you ordered the BikeWing # B01311. This rack has a threaded hitch pin which provides anti-rattle abilities. To lock it you can use padlock # 131D through the hole at the end of the threaded hitch pin.

  • What Size Padlock Can be Used with the Curt Cargo Bag # C18210
  • If you check out the attached review video of the Curt Cargo Bag # C18210 (about the 2:00 mark) our video team member already measured the zippers to have a hole that is about 3/8" diameter so you will just need a padlock with a shackle diameter smaller than 3/8" to use with the bag. The Master Lock Laminated Steel Padlock # ML101 has a shackle diameter of 5/16" so it should work just great for your application. If you would like a smaller diameter shackle then I recommend the Master...

  • Swagman XTC2 Versus XC2 Bike Rack Comparison
  • If I had to choose between the two, I would choose the XTC-2, part # S64670. Not only does the XTC2 have rubber straps to better secure the wheels, but the wheel hoops themselves are much stronger and are slightly raised for better ground clearance. The rack includes a threaded hitch pin, but I would also recommend the locking hitch pin, part # S64029. With the addition of two padlocks like part # 131D, your bikes would be secured to the rack.

  • Fit Looks Tight for Reese Pull Pin Lock Plates for 5th Wheel Trailer Hitches # RP58093
  • Thank you for the photo of your 5th wheel base rail and mounting pin and clip. The Reese Pull Pin Lock Plates # RP58093 you referenced are intended to be used with a pad lock to secure your hitch mounting pin. In order to use these on your 5th wheel you will need to replace your mounting pins (or at least one of them anyway) with a new pin that has a notch in the end. We offer part # 6020PIN. Given the tight fit around your base rails installing these may be easier with a helper on...

  • Can the Swagman Platform-Style Bike Rack 64663 be Installed on a Trailer Hitch
  • Yes, you can use the Swagman Platform-Style 2 Bike Rack # S64663 with a 2" receiver, like the Curt # E-100 that you referenced, or with the bumper mount that comes with the bike rack. To ensure that this fits your application you can measure 6-3/4" from the front end of your bumper as that is about where the rearmost cradle will sit of the Swagman bike rack. If you would like to add locks to this bike rack then part # S64027 will lock the bike rack while 2 of the padlocks # 131D...

  • Replacement Lock Assembly for SportRack Aero XL Rooftop Cargo Box
  • Thank you for providing a photo of your SportRack Aero XL cargo box for which you are looking for a complete replacement lock assembly. I shared the photo with my contact at Thule (parent company of SportRack) and unfortunately they do not have a replacement lock. The original mechanism was, according to my contact, riveted in place and there is no user-replaceable part. However, you can still add a lock to the box with a little bit of creative modification. You will need to drill new...

  • Does the Curt Bike Rack C18065 have an Anti-Rattle Hitch Bolt
  • The Curt Bike Rack part # C18065 does include a threaded hitch pin bolt that will tighten the shank of the rack to the hitch that the rack is installed in. For a lock that you could run through the end of the bolt after it is installed you could use the # 131D.

  • Recommended Options To Securely Lock Cargo To 24x60 Curt Cargo Carrier for 2 Hitches
  • For an option to use with your Curt Cargo Carrier, # C18153, I recommend using an enclosed box like the DeeZee Specialty Series Storage Box - Chest Style - Poly Plastic - 3.6 Cu Ft - Black, # DZ6535P. This box is 35" long x 14" wide x 13" tall, and will require locks like the Master Lock Shrouded Padlock, # 37DAT, along with a cable lock or permanent mounting solution. Another option is the etrailer Cargo Bag w/ Mounting Straps - Weatherproof - 20 cu ft - 59" x 24" x 24", # 988501,...

  • How to Prevent Yourself from Getting Locked in a Trailer that has a Cam-Door Lock
  • You would just need to lock the latch shut after you opened the trailer. That way the only way someone could close the door and lock it would be to first unlock the latch. Most likely you were planning on using a padlock to lock the door closed like the part # 131D, so when the door is open you would just need to put the padlock back on the latch and you would prevent the latch from getting shut while you are in the trailer.

  • Recommended Bike Rack to Use on a Class A Motorhome and Toyota Corolla With a Class I Hitch Receiver
  • Since you are wanting to use a bike rack on a Class A RV you will want to go with one that has been tested and approved for use on an RV. The Swagman Chinook 2 Bike Platform Rack # S64683 that you referenced has not been approved for use on an RV. A similar bike rack that is made by Swagman and is rated for use on an RV is the Dispatch 2 Bike Platform Rack # S64684. This has pretty much all of the same features as the Chinook minus the tilting feature. The reason why there are certain...

  • Lock Recommendations for a Reese Titan Fifth Wheel Hitch
  • I was able to find your order notes so I was able to determine that you bought the Reese 16 Slider fifth wheel hitch part # RP30075. For a lock to secure the hitch to the rails of your truck you would want the part # TR63254. I attached a review video for more info. For a small padlock to lock the handle of the hitch you would want the part # 131D.

  • Recommended Cargo Carrier and Lighting for 2014 Acura MDX
  • Everything looks perfect! Starting with the wiring harness, the Tekonsha T-One Vehicle Wiring Harness # 118628 that you referenced is confirmed to fit your 2014 Acura MDX and is exactly the harness that I would recommend. This custom-fit harness will install by connecting directly to the built-in port behind the driver side trim panel. This will give you a 4-Way at the rear of your MDX to connect with and power a trailer's signal lights. I have attached an installation video on your...

  • Replacement Lock Core And Keys For Sears Cargo Box
  • If you have a lock with a replaceable lock core on your Sears cargo box, then you can use a lock core like part # THLOCKN070. This would replace the lock core on your roof box. You would then need to order the replacement key to match. That is part # THKEYN070. The lock you asked about, part # SR03807 is not a replacement lock for your carrier. If the lock is riveted in place on the roof box, the lock cannot be replaced. You would need to remove the lock and use a hasp lock like...

  • Will the Swagman RV and Motorhome Bike Rack Part # S64663 Clear the Spare Tire on My RV
  • To determine if the Swagman RV and Motorhome Bike Rack, part # S64663 will clear your spare tire, you will need to take some measurements. If you already have a receiver at the rear of your RV, measure rearward from the hitch pin hole to determine the distance needed to clear the spare tire. An easy way to to this would be to stand a long, straight piece of lumber like a 2 by 4 flush against the rear of the spare. Then measure the distance between the 2 by 4 and the hitch pin hole.

  • How to Lock Bikes for Security When Using the Swagman Pick-Up 2 Bike Carrier # S64702
  • The Swagman Pick-Up Truck-Bed-Mounted 2 Bike Carrier # S64702 comes with an integrated lock for the rack itself. If you would like to lock your bikes as well you will need to add a cable lock like part # CAB-10. You can also add some extra security to the adjustment lever by installing a padlock like part # 131D. If you would rather have a truck bed bike rack that has integrated locks for both the rack and your bikes then the Swagman Patrol # S64701 is what you are looking for. This...

  • How to Lock the Curt A25 OEM 5th Wheel Trailer Hitch 16066
  • The only way I can see fit to secure the Curt A25 5th Wheel Trailer Hitch part # C16066 to your 2019 GMC Sierra 3500 would be by replacing the security pins with padlocks as you mentioned. The correct size padlock for you is the Master Lock Padlock part # 131D. The nuts that hold the legs to the feet could be removed with an open ended wrench (crescent is likely too bulky) but they would also need a pair of pliers to remove the cotter pin and they would have to do this for all four sides....

  • Is It Safe to Use Older Husky 5th Wheel Hitch
  • As long as a 5th wheel hitch has been well taken care of and is in good working order there is no reason to doubt that it is safe to use. Unless you were to exceed the weight capacity I see no reason to be concerned. Husky is known for making quality 5th wheel hitches so unless something doesn't look right I'd say you are good to go! If you would like to add a lock you can use the Master Lock Covered, Solid Body Padlock # 131D which has a 3/16 inch diameter shackle.

  • Can Padlocks be Used to Lock Bikes to Swagman XTC Bike Rack
  • I went out to our video studio to take a look at the XTC-2 and found that the padlock hole that can be used to secure the frame hooks of the Swagman XTC-2 Bike Rack, # S64670, into position measures right at 1/4 inches. With this measurement, I recommend going with the Master Lock Covered Solid Body Padlock with 3/16 Inch Diameter Shackle, # 131D. This lock is sold individually.

  • Can Dead Bolt Spare Tire Lock # 4324 Be Used With Smittybilt SRC Oversize Tire Carrier Part 2743
  • According to my contact at Smittybilt their SRC Oversize Tire Carrier Part 2743 can be used with a lock, but it has to be a standard padlock with a U-shaped shackle. Dead Bolt Spare Tire Lock # 4324 will not work. You can use a padlock such as Master Lock # 131D or Roadmaster # RM-305, which has a extra long shackle.

  • Recommendation For Replacement Lock For SportRack AERO XL Roof Cargo Box
  • I did some research and Unfortunately there is no replacement lock available for you SportRack Aero XL cargo box. If you are interested in fashioning a replacement option then you could use a silicone caulk like Item # LT37467 to seal up your lock holes and then drill new holes for a new lock. You could install a simple single-hinged Master lock like Item # 720DPF and then use a padlock like Item # 131D to keep it secure. I have attached a video for you to check out. Contact...

  • Padlock Recommendation for ToyLock Toolbox Mounted Retractable Cable Lock
  • To lock the ToyLok Toolbox Mounted Retractable Cable Lock # LC337118-337117 you can use a padlock with up to a 3/8 inch diameter shackle, like the Master Lock # ML40D. I recommend this lock because of the shielded shackle. If you are looking for a more traditional-style padlock, the Master Lock covered, Solid Body Padlock # 131D is a great option. This padlock has a 3/16 inch diameter shackle. I've attached review videos for both of these locks for you. Also linked you will...

  • Will the Swagman Pick-Up Truck Bed Mounted Bike Rack Fit on a 2007 Ford Ranger w/o Stepside Bed
  • The Swagman Pick-Up Truck Bed Mounted 2 Bike Carrier # S64702 will fit your 2007 Ford Ranger without the Stepside Bed. This bike carrier will snap right into your bed and will adjust to fit the width of your bed. While the Integrated push-button lock secures the rack to your truck bed, you can add a padlock similar to part # 131D on the telescoping arm lever for added security. I attached a review video of the truck bed rack you may want to check out.

  • Recommended Trailer Hitch and Adapter to Use a Yakima 2 Bike Rack With a 2010 Kia Soul
  • There are adapters available like part # HTAD to convert a 1-1/4 inch hitch opening to a 2 inch opening. However, using any adapter will cut your hitch capacity in half, so you will need to ensure that the weight of the bike rack, bikes, and any items in your rear cargo area will not exceed 100 pounds total. The hitches available for your 2010 Kia Soul are class I, with a 200 pound tongue weight rating. When you add the adapter into the equation your hitch capacity would drop to 100...
