Fullstop Nemesis Ultra Wheel Clamp

Availability: In Stock


Purpleline ultra high-security Nemesis wheel lock.

Weighing just over 3kg and being smaller than a shoebox, this caravan wheel lock is easy to install: locate, lock and go.

The unique feature of the patented design nemesis ultra is that the clamp locks to a universal wheel bolt and the clamp itself goes through the wheel as opposed to around it as with a traditional wheel clamp. To use the clamp, you must ensure the wheel bolt is tight; use a wheel bolt indicator to check this.


  • Free handy storage bag
  • Lightweight slimline design for easy storage
  • Prevents wheel rotation and removal
  • Suitable for most caravans
  • Receiver type security with sold secure approval
  • Fitted in seconds
  • This Is For Caravans Only.

Easy to fit and ultra secure

Very high quality product which I was able to install in around 5 minutes on my Pennine folding camper. Plenty of foam backing to protect the alloy wheel. 5 year warranty. Very simple to operate - so much easier than my old rusty wheel clamp. You can literally fit it with one hand in seconds. Also totally prevents removal of the wheel or other tricks of thieves.

Security in Seconds

Whilst getting the clamp initially "set up" took a little while, once this had been achieved the fitting and removing takes just seconds. Great product.

Nemesis Ultra

Good product. Confusing fitting instructions regarding use of washers and no reference to fitting of alternative bolts of different length. Achieved 20% discount on insurance premium by fitting it.

Nemesis Ultra

Ordered this wheel clamp after reading good reviews and found this site to be the best value. Very speedy delivery and I found the clamp very easy to fit to the van. It does require the fitting of a special wheel nut, but that is a once only task. The clamp is nice and light, pops into position very easily, so will make it more likely that I will use it even for short stops such as motorway services.

Arrived promptly and well packed. Fitted to our caravan Bailey Pageant Monarch series 6 (2008) in less than 10 mins. You can remove it in seconds and it fits back onto the wheel in a heartbeat. Best price available. It's a full 5*****'s from us. Highly recommended.

Great bit of kit.

I bought this wheel lock to replace a bulky bulldog wheel lock, this nemesis is so much easier to use and a lot lighter without losing any of its strength. I should of bought one years ago.

nemesis ultra and customer service

The wheel clamp looks like a first rate product - however it didn't fit my Coachman. Sadly the brake drum diameter was greater that the allowed travel of the looking arm that needs to go through the ally wheel. Full marks for your help in telephone conversations and speedy refund when the product was returned thank you - I'm off to hunt for an alternative security device

Nemesis Ultra

Please ignore the rather crap installation video on the Purpleline web site, this product is very good and deserves a far better tutorial video. Please read the instructions that come with the clamp, and contact Purpleline before purchase to establish if this unit will fit your caravan. Caravan Tech Services provided a very fast delivery and at a cost less than the rrp.

Fitting a Nemis Ultra

Good price and fast delivery. I would not describe fitting as straight forward but there is a good Dutch video on YouTube. I experienced several difficulties with installation which took me an hour but once fitted it does take seconds to put on and take off. Points to be aware of: current new Alco chassis have a broad brake drum which made it difficult to install through the alloy wheel of my van and coverin most of the wheel bolts. This means some of them are exposed, however, with security bolts fitted this will not be a problem. Secondly, test the locking mechanism and WD40 spray it as I experienced problems is undoing the lock to remove the device, furthermore, tighten the barrel lock when in place with the alen key otherwise it will simply rotate in its seating and you won't be able to unlock it. The instructions are not clear. Hope these points help as I am delighted with the product

This is my 1st caravan (a Knaus Tab 320) and I was unsure if it would fit. Looks a dit daunting to make up but a quick read of the instruction and it was fitted. It is very well made and so easy to fit and remove. Perfect product in my opinion. The service from Caravan Tech sales was outsatanding and a great price too. Chuffed!

Nemesis ultra

Very pleased with the buying process, the wheel clamp arrived the day after I ordered. The nemesis ultra seems very well put together and works as described. Interestingly, before I ordered, I emailed Purpleline to ascertain the suitability of my caravan, didn't get a reply. I have given them the benefit of the doubt and assumed the emails didn't get delivered, (I did get an automated delivery receipt). My advise use the telephone, I have a speech problem, so didn't.

full stop nemesis wheel clamp

Arrived next day delivery. not as easy to fit as you would have thought. This could be more about technique than anything else. Otherwise once on does as it says on the tin

nemesis ultra wheel-lock

Very easy to fit, and much easier to use than my old heavy rusty wheel-lock. Arrived quickly from supplier with clear instructions. Very pleased.

Nemesis Ultra

Smart looking - Good Engineering and top quality finish/appearance. Well packaged and presented. Easy to fit once fiddly initial installation is done. Seems to jamb when grub screw tightened but this can be overcome by tightening and loosening grubscrew when fitting or removing. Overall 9/10 for a top quality security device. Easiest to manage by far than available competition. Stows easily and compactly in van.

I have to park my caravan against a wall. (Nose in) With the Al-Ko Wheel Clamp 9 times out of 10 I had to jack up the van to move the wheel. NOW No Problem!. I stop the van when the hitch just touches the wall then fit the Nemesis Clamp. The time taken to fit is the time it takes to turn the key!!! At a guess '3 seconds'

Having the Alko wheel lock which is difficult to fix I wanted a secure lock that was quick and easy but also very secure. I found it in the Nemisis, a great lock!
