  • How Long are the EZ Grip Bungee Cords when Stretched Out
  • I went out to the warehouse and pulled EZ Grip Bungee Cord, 32 Inches, # 3031DAT, and the 24 inch model # 3030DAT, to measure them for you. The lengths listed are the unstretched lengths. When stretched out, each model can be as long as twice the original length. About 64 inches for # 3031DAT and 48 inches for # 3030DAT. I made a short video showing the elasticity of the bungee cords for you.

  • How To Prevent Trailer Theft Beyond Hitch and Coupler Locks
  • One easy way to prevent someone from removing the ball would be to use a ball mount that has the ball attached (welded) to the shank. That way you won't have to weld a ball to a shank that isn't meant for that type of modification. Some examples include # 45325 or something adjustable that locks like # DTALBM6600. A Wheel lock such as # RA-25 would also be a good idea. The trailer would not be able to be moved with a wheel lock like this on it. And the ball mount/ball may be enough...

  • Combination Reset for Master Lock Safe Space Portable Storage Box with Combination Lock
  • In order to reset the combination on the Master Lock Safe Space Portable Storage Box # ML5900D, you will need access to the inside of the box. The reset lever is a small, light gray lever on the top left hand side of the combination dial. You will need to push the lever to the right while setting a new combination. I have attached a photo showing the location of this lever for you, as well as a product review video that may help. If the box is closed and the combination is forgotten,...

  • Electric Winch Recommendation to Raise and Lower a Pop Up Camper Top
  • The Master Lock Electric Trailer Winch # 2953AT that you referenced only has a power load in function. So you would be able to raise the top of your camper but not be able to lower it in a controller manner. For a winch that can power in and out that would work better for you check out the part # 1220210. For pulley blocks you might also be interested in the part # SW2229A.

  • How to Reset the Combination on a Master Lock Gun Trigger Lock
  • If the Master Lock Gun Trigger Lock # 94DSPT is locked and you have forgotten the combination you will have to reset the combination. To change the combination you will need to set dials to combination (combination is preset to 0-0-0 by factory). With dials set to combination, move release lever to open, or up, position. Pull apart the two sides of the gun lock. Next, you will need to use a pen to press and hold the reset button that is on the left side of the lock and select a...

  • Any Way to Reset Forgotten Combination on Master Lock Backpack Lock
  • There's no way to reset it, but you might be able to hack it. Set the three wheels so they all read 0. Then, as you're pushing on the shackle begin turning the last wheel slowly backward from 0 to 9, 8,7, 6 etc until you feel resistance on the dial. It's important that you keep pressure on the shackle as you're doing this. Do the same thing for the middle wheel and the first one, turning the dials backwards from zero until you feel resistance on the wheel. If this doesn't do the trick,...

  • Recommended Trailer Locks for Rented U-Haul Trailers to Secure When Connected and Disconnected

This kit will give you a hitch pin lock for your ball mount, the trigger lock for the trailer when connected or disconnected from you vehicle, and the coupler lock to secure it when disconnected.

  • Coupler Lock With 1/4 Inch Diameter Pin Recommendation
  • For our hitch receivers, we offer hitch receiver locks that have either 1/2 inch or 5/8 inch diameter pins. Depending on what you intend to use the locking pin for we do have other options available. We carry locking coupler pins that may work for you. The first lock I recommend is the Master Lock Adjustable Trailer Coupler Lock, part # 2847DAT. This is a 1/4 inch diameter pin that has a keyed lock and is adjustable to fit lengths of 5/8 inch, 1 inch, and 2 inch. Another coupler lock...

  • How to Correct Frozen Hitch Lock 1480DAT That Will Not Open
  • After a long period in place a lock mechanism can stick and make it tough to get the key in it, or to get the inserted key to turn. There are a few suggestions I can offer to you to get your lock # 1480DAT open. You can spray a bit of aerosol white lithium grease into the lock. Do not use powdered graphite as it will eventually harden. A small amount can also be applied to the key before it is inserted. The keys themselves sometimes will benefit from a bit of fine (500 grit) sandpaper...

  • Can the Masterlock Electric Trailer Winch Be Used in Reverse to Pay Cable Out of the Winch
  • For powering loads in and out I would recommend the Superwinch LT2000 Electric Utility Winch, 2,000 lbs, item # 1220210, which also includes a freespooling clutch for fast payout. The Master Lock Electric Winch,Trailer Winch, item # 2953AT, is designed for power load in only. I cannot recommend any modification or alternate use of the winch other than what the manufacturer recommends.

  • Extra Long Locking Trailer Hitch Pin for 2015 Toyota Tundra
  • The factory installed hitch on the Tundra is wider than a typical 2 inch receiver, so a normal 2 inch hitch lock won't fit. We offer an extended length lock, part # RH5-XL. Multiple locks are available keyed alike, use the drop-down box on the product page. We don't carry a lock with the part number you mentioned, so I tried looking it up online and found no result. I'm not sure where you'd be able to get a longer pin for your particular lock.

  • Replacement Hitch Pin for Thule Bike Rack
  • Your Thule bike rack uses a threaded hitch bolt, both for security and to hold the shank of the bike right tight up against the side of the receiver tube to prevent the bike rack from wobbling around. Because it uses a proprietary threaded bolt, you unfortunately wouldn't be able to use the Master Lock # 1470DAT lock you mentioned as the threads would prevent the hitch pin from working. If you lost the threaded hitch bolt as well as the lock itself, you'd need part # THSTL2. If you're...

  • Recommendation for Electric Winch To Pull 24 Foot 3300-Lb Grady White Boat on to Trailer
  • Because of the length of your boat I would recommend the Dutton-Lainson StrongArm Electric Winch, part # DL25200. This DC-powered winch is designed for boats up to 4,000 lbs and includes a wiring harness for easy installation. I am including a link to the installation instructions on the winch. The Master Lock Electric Trailer Winch, part # 2953AT, you have referenced, has a maximum boat weight capacity of 5,000 lbs , but only a maximum boat length of 18 feet. I would not recommend this...

  • Which Coupler Lock Set is Best for Use with Atwood Trailer Coupler 81911
  • The Atwood Trailer Coupler 81911 that you have on your A-frame trailer can be locked in two ways, by securing the latch and by blocking entry of a hitch ball. The latch mechanism on the top can be locked with an item like the Dead Bolt # 7690. (This latch lock is one of the two locks included in part # 7685, which is our reference for the CT Johnson part RHC32.) But please note that this latch lock has a center span of only 1/2-inch; the coupler latch on your # 81911 requires a latch...

  • Coupler Lock for Vintage Coupler on 1949 Airstream
  • Thank you so much for the photos and for your 2" coupler I recommend the Master Lock Trailer Coupler Lock # ML389DAT.

I have added links to a pair of video reviews for you to take a look at as well.

  • To set the lock passcode for the MasterLock Safe Space Box part # ML5900D that you referenced you will need to hold the passcode set lever above the dial while you change the code to your desired passcode. When you release it will be set. To get the lever to release the passcode will have to be entered into the box. Since yours doesn't want to move now that you changed it that would indicate that it is set to the last passcode that you entered. Check out the review video I attached...

  • Recommended Keyed Alike Trailer Coupler Locks For Multiple Trailer Application
  • For your keyed alike trailer couplers, I recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers, # DT25013KA. This lock secures your coupler from the top and bottom. It is a noticeable theft deterant and it has a tube key lock cylinder to provide better security. It has an anti-drill pin and bolt blocked locking system prevents prying open the lock. Fastway has been shown to work on the most different styles of couplers. Other options for keyed alike...

  • Best Coupler Lock Options for a 2015 Ranger Trail Boat Trailer
  • We have a few different universal options that I recommend choosing from. The Master Lock Trailer Coupler Lock # ML389DAT is a great option because it has a bright red color to draw attention to the fact that there is a lock on the trailer. Since the idea behind a lock is to deter theft, drawing attention to the lock will help to intimidate a would-be trailer thief. One of the most popular options is the Fastway Trailer Coupler Lock # DT25013KA. You can order this lock keyed alike...

  • Superwinch LT2000 Winch Wiring and Installation on 2010 Polaris Sportsman 500 HO
  • I attached a set of the installation instructions and attached a picture that I pulled from them that shows where all of the wiring connections will need to made. I do not have specific written installation instructions for your 2010 Polaris 500 Sportsman but I did attach a video of this winch being installed on a very similar 2012 Polaris 500 Sportsman that will detail how we did it for that ATV. The process would be basically identical for you.

  • Recommended Coupler Lock that is Keyed Alike

It features an anti-drill pin to discourage attempts to drill out the lock and a bolt-blocked...

  • Trailer Coupler and Wheel Locks to Deter Trailer Theft
  • master Lock trailer coupler lock # ML389DAT would be a bit more secure than lock # 377DAT in my opinion because it would be a little more difficult to pry off. When it comes to locks the best solution is redundancy. In other words more than one lock. You may want to consider also adding a wheel lock such as # RA-25 or # WI490. If a thief sees a coupler lock and a wheel lock they are likely going to move on to an easier target.

  • Can the Master Lock Trailer Coupler Lock # 377DAT be Rekeyed
  • The Master Lock Coupler Lock, # 377DAT, is not rekeyable. Master Lock does not offer replacement lock cores for this particular lock. If you know the key number that was stamped on the original keys, you can order replacement keys using the Replacement Key for Master Lock Coupler Locks, # MLK1. If you do not have the original keys and the lock is stuck on your trailer, you can drill out the lock core to remove the lock, but you would need a new coupler lock to secure the trailer. If...

  • Tips for Unlocking a MasterLock Coupler Lock that Won't Release from a Trailer
  • I would try hitting the locking mechanism with some WD-40 or a similar spray lubricant. Most likely if you get some lubricant on the portion of the lock that moves you will get it to brake free. If there is any tension on the trigger portion of the lock that could cause it to bind up and not release either. Also, make sure you have the position of the lock all the way in the unlock position so that it will release.

  • Can 12 Volt DC Trailer Hitch Wiring From a 7-Way RV Connector be Used to Power a Winch
  • The wiring in your hitch is not rated for use with the Master Lock Electric Trailer Winch # 2953AT. The wiring could overheat and cause damage to the hitch wiring, the winch, or even your vehicle. You will need to wire the winch separately. I recommend the Winch Trailer Wiring Kit # SW1520. The kit contains properly sized wiring and connectors to make use of the winch easy and removable.
