BLOCKSTEM is a P3 Thatcham-approved anti-theft advice for tractors and earth-moving machines, made from C4 steel with hardener, which is applied to the steering ram on full lock.
BLOCKSTEM is approved and endorsed by all major underwriters and by JCB Insurance, who offer up to 40% discount on premiums.
BLOCKSTEM is an innovative anti-theft device designed for vehicles with RAM operated steering.
The lock is very easy to apply and can be in place in minutes.
It’s very simple. The device is placed round the RAM and locked into place with an individual key, specific to that lock only.
Because it is made of hardened steel, it’s impervious to mechanical attack.
BLOCKSTEM has been thoroughly tested, approved and accredited by Thatcham.
The theft of agriculture vehicles is increasing to the extent of over £1 million per week.
BLOCKSTEM is a mechanical device. It is not dependent on electronic systems that are increasingly vulnerable to sophisticated theft devices.
It also has the added economic advantage that the lock can be used on other machinery with the same dimensions.
