Neffco Security Products:
Protecting Your Most Important Asset

Trust the "Dawg" for Truck & Trailer Theft Prevention

We don’t have to tell you that theft in the commercial trucking industry continues to grow, both in the number of instances as well as the average cost for
stolen trucks, trailers and the cargo. It’s not just the value of the stolen assets but also the time, anxiety and frustration that comes with filing theft reports,
dealing with your insurance company and most importantly, getting back on the road, making money. Whether you own a fleet of trucks or you are an
independent driver, finding security products that work and are easy to use, is critical to protecting your investments.

Neffco Security Products have been designed and manufactured in the USA, to be sturdy and dependable deterrents to theft. However, security products are only effective if they are used every time. The easier they are to install and use, the more likely your drivers will always use them. The WatchDawg, JackDawg
and LugDawg are products that install easily and will be used, providing the security you are looking for.

Neffco Technologies theft security devices are easy to install and even easier to use. The easier they are to install and to use, the better it is for transportation companies and their drivers. With that in mind, Neffco Technologies began in 2003 with the WatchDawg parking brake lock. It was a better and easier solution to securing the brake release. Since then, we have added the JackDawg landing gear lock and the LugDawg truck wheel lock for even more security against theft for the commercial truck industry.

The LugDawg Wheel Lock is a wheel theft prevention device. It is a lug nut cover for all hub piloted wheels with M22x1.5 studs. It conveniently covers the existing lug nuts.

Construction includes a durable aluminum outer housing and plated steel inner hub nut. A 3/4″ hex bit is required to install and remove the hub nut of the LugDawg. Once installed, a lock cylinder obstructs the hex socket preventing removal. The aluminum housing simply spins freely and will not loosen the LugDawg.

Tips to Help You Prevent Truck, Cargo & Trailer Theft

No one thinks that truck or cargo theft will happen to them, but it seems the number of stolen trucks and the amount of lost cargo increases every year. Thieves are looking for the easiest targets so the best way to reduce your risk is to make sure your semi-truck, trailer or other types of commercial trucks are the ones that pose the strongest obstacle to theft. Thieves will want to move on to easier targets.

The following ideas are meant to help you plan ahead to reduce the risk of truck theft, trailer theft and cargo theft. Some of this information will probably seem like common sense measures to prevent theft and damage to commercial trucks but it is still worth talking about.

Semi-trucks, trailers, dump trucks, deliver trucks and other types of commercial trucks are all highly visible targets for truck theft. Having an awareness of what you can do ahead of time such as planning your route, pre-determining safe locations to stop and rest, as well as having security devices installed on your truck and trailer, can bring some peace of mind that you are prepared to protect your assets and your cargo.

Leaving Your Truck Un-Attended

When you leave the cab of your truck, always lock the doors and keep your windows closed.
This is probably the most obvious, no-brainer statement we can make but think about how any times, you jump out of your truck to
make a quick pit stop and you don’t bother to lock up or even roll up the windows. You just created an easy target for truck theft. Just
take a moment and secure the cab of your truck.

Don’t leave the keys in the truck or in the ignition.
Whether you hide the keys or not, you don’t need to make it easier for a thief to steal your semi-truck and get away with the cargo on board. Truck security and theft protection begins with simple steps like taking your keys with you.

Park in well-lit areas whether at a truck stop, rest area or at the terminal.
Protecting your semi-truck, trailer and other commercial trucks means being aware of your surroundings and that begins with parking in a well-lit area of the terminal yard, truck stop, rest area or any location where you must leave your truck un-attended. Obviously, thieves do not want to be detected so they are much more likely to go after commercial trucks that are not as visible to lights, security cameras or traffic going by.

Anti-theft devices make it obvious that it’s not going to be easy to steal your commercial truck.
We are big believers in using visible Anti-theft devices such as WatchDawg air brake lock and JackDawg landing gear lock. Not only do these anti-theft devices work to protect your truck and cargo, but they are visible warnings to a thief that it won’t be easy to try.
Some other common and visible anti-theft devices include:

  • Steering wheel lock
  • Steering column collar
  • Wheel locks
  • King Pin locks for trailers

Vehicle alarms work.
Having an alarm going off when a thief tries to break into your semi-truck or trailer will fend off most thieves. Having an alarm system is great but clearly displaying decals or stickers so a thief can see that your truck is protected with a security alarm system will many times keep them from even trying to steal your cargo.

Tracking Systems are still a good investment.
So what happens if your semi-truck or trailer is stolen despite your best efforts to protect your property? Even the best plans and truck theft protection devices sometimes are not enough to keep a determined thief from taking your truck or stealing the trailer off of the truck. Having a GPS tracking system installed is a good idea. If the worst does happen, it could help you to locate your stolen truck much sooner and recover your asset. There is no guarantee, but it could make a difference and help to limit your loss.
