10mm diameter high tensile chain

Although the
stainless steel shield is an important part of the 4wd Wheel Clamp. Its the 10mm diameter high tensile chain that secures the stainless steel shield to the leaf springs or tubular frame, most caravan chassis.
high tensile chain wraps around the leaf springs

Or another part of the chassis if the vehicle has coil springs and / or piston suspension.

why did we choose to design 4wd Wheel Clamp using 10mm diameter high tensile chain
I, William Flynn have no idea when the first modern wheel clamp was first designed and manufactured.
but what I do know is
In August 2005 when I decided to re-design the wheel clamp, all other wheel clamp brands are made by one of three methods and still are today February 10, 2025.
- 3 arms that wrap around the width of the tyre, Klamp It Wheel Clamp
- a clamp that goes through the wheels rim, Haigh Wheel Clamp
- a rod that goes against the wheels rim, Ark Wheel Clamp
Klamp It Wheel Clamp

Haigh Locking Wheel Clamp

Arc Wheel Clamp

other wheel clamp brands
- from our research all but two wheel clamp brands are made in China including the above three brands
- most wheel clamp brands only fit one diameter wheel or tyre width properly
- some say their wheel clamp will fit a 165 - 175mm width tyre but as you must realise it will only fit the 175mm wide tyre properly
this means before purchasing a China made or other imported wheel clamp brand you have to measure the diameter of the wheel, the width of the tyre you want to protect and how far the wheel hub protrudes from the face of the wheel then find a retailer that sells the size you require - cannot use the wheel clamp on another vehicle with a different diameter wheel or tyre width
- only wraps around the tyre and does not wrap around the vehicles leaf springs, tubular frame or another part of the chassis when the trailer has coil springs and / or piston suspension
- some wheel clamps can be removed by deflating the tyre
august 2005 my mission was
To design a wheel clamp that not only wraps around the width of the tyre, it also had to be
secured to part of the vehicles chassis
such as
The leaf springs or tubular frame (most caravan chassis) or another part of the chassis if the vehicle has coil springs and / or piston suspension.
that is what I did
after almost 12 months of
Designing and testing various methods to secure one wheel on vehicles in my factory in Kelmscott, Western Australia.
january 2007
I finally had a unique designed wheel clamp and a unique method to fit it to a wheel compared to all other wheel clamps sold world wide.
march 2007
We sold our first Australian made 4wd Wheel Clamp to a purchaser in Sydney to protect his trailer that had both coil springs and a piston suspension.
how this 4wd Wheel Clamp fits all size wheels
The stainless steel shield and a single length of 10mm diameter high tensile chain and one of two high security locks based on if you purchase the Enforcer 4wd Wheel Clamp or Supreme 4wd Wheel Clamp.
Place the high tensile chain through the holes in the stainless steel shield then wrap the chain around the wheel and leaf springs, tubular frame (most caravan chassis) or another part of the chassis if the trailer has coil springs and / or piston suspension.
note
10mm diameter high tensile chain cannot be cut with a bolt cutter no matter how long the bolt cutter is.

how to stop thieves stealing your valuable towable vehicle
We could have included thin 4mm or 6mm diameter mild steel chain, most people use for security, with each 4wd Wheel Clamp.
If we did both Enforcer 4wd Wheel Clamp and Supreme 4wd Wheel Clamp would be about 52% less to buy but there was no reason to do so.
why
The 4wd Wheel Clamp would be just another visual deterrent wheel clamp as other imported wheel clamp brands.
plus
For about five dollars at Bunnings, Mitre 10 or any other hardware shop a thief can buy a short 12 inch long bolt cutter to cut thin 4mm or 6mm diameter mild steel chain and your $10,000 to $90,000 or more vehicle is stolen.
if you believe
A cheap imported wheel clamp made from thin mild steel or about 0.2mm mild steel tube is going to stop thieves stealing your $10,000 to $90,000 or more vehicle then think again.
as the saying goes
you get what you pay for
think about the following
If your towable vehicle was stolen what would it cost you to purchase a new one of the same type, quality including all the extras you purchased for it over the years ?
Now you have calculated the replacement cost will the insured value buy you the same if stolen, we doubt it.
how much out of pocket
will you be if your vehicle is stolen
let us face facts
No matter the insured value and how reliable your insurance company is, if your vehicle is stolen and you make a claim the insurance payout
will never cover
the full replacement value
plus
Your next insurance policy will increase in cost, they always do after a claim.
note
No matter if you are insuring your camper trailer, caravan, boat, jet ski or house the main purpose of insurance should be for problems out of your control such as
but not theft
about 95% of theft is preventable
- having a high security wheel clamp such as the 4wd Wheel Clamp fitted to one wheel on your camper trailer, caravan or boat trailer when its not being towed
- installing security screens on your house windows and a security door in front of the front door
