Expert Answers about Master Lock

  • Does Master Lock Backup Camera 4843DAT Provide a Mirror Image View?
  • The feed displayed on the monitor for the # 4843DAT would look the same as if you were looking straight out of the back of the vehicle. The image will not be a reversed or mirror image, as the camera function is to assist with navigating your vehicle while in reverse.

  • Will Trailer Hitch Receiver Lock with Integrated Cable Fit a Curt Class III Trailer Hitch
  • The Class III Curt trailer hitch # 13534 uses a 5/8 inch diameter hitch pin. The Trailer Hitch Receiver Lock, # 1470DAT, has a 5/8 pin and a 1/2 inch pin so it is compatible. So the 1/2 and 5/8 inch you are seeing is the diameter of the pins and consequently these are the 2 most common hitch pin hole sizes.

  • How Parts of Coupler Replacement Latch Kit Go Together
  • The Shelby class II coupler which uses the # CP02-050 repair kit is very similar to the Master Lock # 2833AT coupler you mentioned. I have provided an exploded drawing showing the individual parts of the # CP02-050 and the order that they are installed. Although the coupler shown in the diagram is different than the # 2833AT you have, the latch for your coupler should be pretty similar.

  • What Brake Lock Will Work With a 2012 Honda Shadow Spirit With Spoke Front Wheel
  • To determine if the Master Lock 3 Inch Disc Brake Lock, part # 8304DPS will fit your 2012 Honda Shadow Spirit you will need to take a couple of measurements. The lock pin has a diameter of 0.40 inches or slightly less than 7/16 inch, so you first need to measure a heat dissipation hole on your rotor to see if you have an opening that will fit a 0.40 inch pin. Next, measure the distance from the outside edge of your rotor to the center of one of the heat dissipation holes and if that measurem

  • Can a Trailer Winch be Plugged Into an AC Power Outlet at the Back of a Vehicle
  • We do have some AC powered winches but the Master Lock Electric Trailer Winch, # 2953AT, is a DC powered winch so it cannot be plugged into an AC power outlet, even on a vehicle unless you do like you said and hardwire it. Otherwise you would attach it to the vehicle battery or to an alternate car battery if it is not feasible to attach it to the car battery. I have added a link to the AC powered winches we do carry.

  • Will Master Lock Boat Trailer Anti-Theft Alarm # 4840DATSEN Reset Itself After Being Triggered
  • After speaking to my contact at Master Lock, I have found the alarm on the Master Lock Sentry Boat Trailer Anti-Theft Alarm System # 4840DATSEN resets itself 30 seconds after being activated. The alarm can be triggered if the trailer is disconnected from the tow vehicle or if the wires are cut. It will also detect when a light has been burned out. The trailer lights can be disconnected via a remote while the trailer is under water.

  • Recommendation of Trailer Coupler Lock to Fit a Titan 2-5/16 Inch Coupler
  • The Master Lock Universal Trailer Coupler Lock, part # 379DAT, you have referenced will fit a 2-5/16 inch trailer coupler.

  • Availability of Hitch Lock and Cable To Lock Hitch and Bikes on Yakima DoubleDown Bike Rack
  • To lock your bikes to your Yakima DoubleDown bike rack and to lock the bike rack to the hitch I would recommend the Yakima DeadLock Hitch Lock and Cable, part # Y02411. This part will attach to your existing Yakima hitch bolt to lock the bike rack to the hitch and includes an integrated cable that installs in the bike rack arm and secures the last bike to the rack so none of the bikes can be removed from the rack. The locking cores are keyed alike and can be changed out if needed to match other

  • Solid Blue Screen and Blinking Light on Master Lock Backup Camera on 2012 Chevrolet Silverado
  • In-car and headset bluetooth devices operate on the same 2.4 GHz frequency, so your experiment would be similar to your truck if you had the bluetooth searching or connected as far as the various components are concerned. The main difference between your experiment and the installation on a vehicle is the distance between the transmitter and the monitor. The signal quality will improve by placing the transmitter closer to the monitor, even with devices that could cause interference. I verifie

  • Backup Camera Recommendation for Mounting on a 27 ft Trailer
  • I believe the best possible solution I can recommend for you would be the HindSight Wireless Backup Camera # 67300. This camera is wireless so you will not need to run wires from your vehicle to your trailer, and it has a very impressive range. I spoke to my contact at Tow Ready once before and they told me that the unobstructed range of this camera is 300 ft, and that in most situations where there are obstructions it has a range of 100 ft. With this system you have the option of adding additio

  • How Tight Will Master Lock Universal Trailer Coupler Lock # 379DAT Fit on 2-5/16 Inch Demco Coupler
  • The Master Lock Universal Trailer Coupler Lock, part # 379DAT, is designed to work on all three hitch ball sizes, 1-7/8 inch, 2-inch, and 2-5/16 inches. Since it fits all three sizes it will not be able to be very tight, but you will want to make sure to slide the body of the lock up against the coupler as far as possible when attaching the lock to the coupler. As long as the lock cannot be removed after you lock it to the coupler it will work just fine in keeping somebody from connecting to

This lock is designed to fit all 2 inch trailer hitches and is also designed to work with OEM trailer hitches that have limited clearance for a hitch pin because the hitch pin hole sits close to the hitch crosstube.

  • Trailer Alarm Recommendation
  • The best recommendation I can offer you is the Master Lock Alert Toolbox and Tool Security System with Remote # 8254DAT. This 100-decibel alarm can mount to virtually anything, including your trailer, and once armed it will go off if a sudden jolt or movement is sensed. This product is intended for toolbox lids but there is no reason it would not work on your trailer. I would recommend you install it somewhere hidden and as much away from the elements as possible.

  • Can the Master Lock Wireless Backup Camera be installed on the Back of a Boat Trailer
  • First, the Master Lock wireless backup camera, # 4843DAT, can transmit 125 feet so the distance from the back of the boat to the truck will not be a problem. You could hardwire the transmitter directly to 12 volt power but it would be on all the time. I recommend hardwiring it into a running light circuit on the trailer so it comes on with the running lights like it is made to do. Make sure any wire connections are water tight by using shrink tubing or liquid electrical tape, # SWC50122. And

  • Will the Master Lock Pedal to Wheel Vehicle Lock work on a Large Truck
  • I spoke with my contact at Master Lock and found that the Pedal to Wheel Vehicle Lock, # 256DAT, measures 30 inches from inside hook to inside hook when fully extended. If the brake pedal in your rig is more than 30 inches away from the steering wheel, then this lock will not work. I have attached a photo showing this measurement. Depending on the inner diameter of your steering wheel, you could look into a steering wheel lock like the Titanium High Security Steering Wheel Lock, # 263DAT

  • 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.

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 winch

  • Portable DC powered 12 Volt Vehicle Winch Recommendation for a 1999 Toyota RAV4
  • There are several things to consider when choosing a winch. If you are looking at having to potentially use the winch to retrieve the 1999 Toyota RAV4 then you need to consider the incline, terrain, angle, and total load. For example a winch rated for 2,000 pounds pulling a rolling load on level ground can pull much more than that 2,000 pounds. On a 10 percent slope for example it can pull 10,050 pounds. But a steeper incline will reduce the capacity. If you foresee yourself in all sorts of d
