Trailer Security by SAS
So, you’ve got yourself a shiny new trailer on your driveway, and doesn’t it look lovely! …But you might not be the only one who thinks so, trailer theft is a big problem in the towing world, and it is only getting worse. Thankfully SAS stock a huge selection of security accessories, dedicated to keeping your trailer safe and secure when you’re not keeping a watchful eye on it.
Trailers that aren’t secured correctly represent an ideal opportunity for a thief; they can be coupled up and towed away in seconds. You will likely find that adding the correct security measures will reduce the insurance for your trailer due to its better protected status. Trailer security accessories can come in many different forms, with a large range of shapes & sizes. We will take you through a few of the must-have trailer security items that SAS recommend, all of which are insurance approved!
SAS Wheel Clamps
SAS have developed a huge variety of wheel clamps for trailers. These are great accessories to fit when you are storing your trailer for longer periods of time. They are simple to use and very effective at stopping the trailer being towed away. Just use our handy SAS Wheelclamp Selector Guide to find the right wheel clamp for your wheel. The SAS Wheel Clamps provide an excellent level of protection from thieves by stopping the rotation of the wheels of the trailer. High-quality wheels locks, like many from SAS, ensure the wheel nuts are also covered to make it impossible to remove the wheel of the trailer in an effort to tow it away with a replacement wheel.
SAS provide wheel clamps that are suitable for both single axle and dual axle trailers. One downside to wheel clamps is their size. Although their size can be reduced for storage, and some are supplied with carry case to make them easier to use if they need to be transported often. We would recommend an SAS wheel clamp as a security device that is fitted where the trailer is stored for days.

SAS Hitch Locks
SAS Hitch Locks are an extremely effective way to stop your trailer being hitched up to another vehicle. SAS hitch locks cover the hitch coupling of your trailer and stop thieves from tampering with the hitch and the bolts surrounding it*. A hitch lock is not only effective at stopping your trailer being hitched up, but also stopping it being unhitched from your vehicle, adding an extra level of protection that stops any damage occurring to your trailer. SAS hitch locks such as the SAS Fortress Range are effective when coupled and uncoupled.
Hitch locks are a great deterrent to thieves due to their robust design, requiring a substantial amount of force to break them. All of the SAS Red Range hitch locks are insurance approved, meaning they have had to pass various security checks, this ensures they are of the highest quality. Hitch locks are a great accessory to take with you on any journey as they are small enough to be transported easily, while remaining highly effective against any theft attempt.
Use the SAS Hitchlock Selector Guide to find the right one for your hitch coupling.
*Please note not all Hitch locks cover the hitch coupling bolts.
SAS Chains & Padlocks
Chains and padlocks are a more traditional way of securing your possessions. But just because they are slightly more old school doesn’t mean they are any less effective. When it comes the chains and padlocks, size matters! SAS chains, such as the SAS 14mm Heavy Duty Security Square Chain & Padlock (2m), have hardened steel chain links measuring a whopping 14mm in diameter, they are tough! Chains are a great way of securing both trailers and any other items you might have that you don’t want to go wandering overnight. All the SAS chains have been designed to be extremely tough, they are covered in protective cloth sleeve material to making it even harder to cut through, while also stopping the chain damaging your trailer or equipment while you are using it. Chains are a fantastically useful security mechanism as they are highly versatile in their use, and very easy to transport.
SAS Ground Anchors
What is the use of these chains if you have nothing to connect them to, this is where ground anchors come in. SAS Ground Anchors give you an extremely strong point to lock your chain to. SAS Ground Anchors provide an immovable anchor point, with built-in (concrete-in) options with cross brace pins to stop them being pulled out of the ground, or bolt-down versions with anti-tamper ball bearings to stop the removal of the ground anchor. Although you must either concrete-in the ground anchor or bolt to secure masonry, once done, you will have a safe and secure locking position for years and years!
SAS Security Posts
The SAS Security Posts are another great option to block your trailer in, if you are keeping it in a specific place most of the time. With the optional towbar accessory you can hitch your trailer to the post and lock it with a SAS hitch lock too.
If you have a wider area to secure, this can be done using a combination of the different variants available. There are fixed, removeable and folding security posts options.


Investing in the correct security accessories for your trailer is a sensible idea, we would always advise doing so on day one of your trailer ownership – before it’s too late!
Security today for a safer tomorrow!
Security accessories will give you peace of mind when you are leaving your trailer outside, and normally result in a lower insurance premiums due to their recognised security advantages.
