When I fitted the Bulldog DC400 Auto Clamp the first few times I struggled a bit, but once it was on I was very pleased with it. It fitted well without damaging the wheel or the bodywork. After a few goes I found a really simple way to fit it onto our Elldis Autoquest, and now I can get it off and back on in a very short time without much effort. As we have a false grass hard standing, kneeling to fit it is no problem, but I will need to take a mat or similar for use away from home. The design and quality seem very good and the bright yellow colour can be seen from the road, hopefully adding to the deterrent value.

We purchased a motorhome earlier this year and store it on our driveway. As there is a significant risk of passing traffic and pedestrians the level of security contained within the motorhome was adequate but we wanted to be showing a visual deterrent to the opportunist would be thief.

The large bright yellow highly visible product was in our opinion the most effective under all heading.

The only problem with the wheel clamp that we are experiencing is the awkward positioning of the feed bar into the locking area. We have tried several methods or fixing the wheel clamp into the correct alignment to achieve being able to lock into position, but we still have four or five attempts before being successful. We are thinking that as the item is large and cumbersome...it has to be to fit the wheel size that is as it should be. Apart from the above delighted with the item and the level of service and advice we received from the supplier.

Thank you.

Having struggled to get a security device large enough to fit the wheels of my Peugot Boxer Van Conversion I was pleased to come across this. It is a little bit tricky to fit / remove until you get the knack! Then it is dead easy - on or off in about 15 seconds. Very solid and a great visual deterrent. Storage could be an issue as it is a little cumbersome but then what do you expect from a solid piece of engineering like this. I would be very happy going away with it in the van and then immediately putting it in place on the vehicle when not camped up. So what's the issue!

High Quality. Well Made. Very Visible. Ideal for when parked on driveway.

Takes a lot of space when stored, not easy to take in with you in a motorhome. Does not fold flat. But then, it is built like a tank. Heavy. A bit to big to take on holiday so have a smaller foldable one for that.

Wow! What an excellent product - does exactly what it says on the box. Just what we need while our motor home isn't being used.The Bulldog DC400 really is a strong piece of kit and well worth the money spent. We now have complete peace of mind when away from the van. Just on it's visability alone, should deter any would be thief. I would thoroughly recommend purchasing one of these and, in fact, have already been singing its praises to a fellow motor homer who wanted advice on social media, and would do so again and again. Thank you Bulldog..

I thought the product was very well made and strong. It is for securing our large motorhome. It is very easy to put on and take off (which is ideal when on a campsite) once you know what you are doing. I feel that due to the secure way of fixing onto wheels and the weight of it it would be quite difficult for someone to remove it quickly for stealing vehicle. All in all an excellent purchase which was decided on after days of researching into best one for our needs. I would not hesitate recommending it to others.

The Bulldog DC400 is well built and just the job for me. My Motorhome is parked on our driveway alongside the footpath and is easy to see. The clamp on the front wheel is highly visible and a great deterrent. It is so sturdy that anyone trying to get it off without the keys is going to wake the neighbours. It’s easy to assemble to fit the size of wheels and reasonably easy to fit in place but it is quite heavy, that’s why eae of use inly gets 4 stars. The delivery from Safe was on time as promised and I’d use them again.

The clamp is well made and once fitted deters anyone who tries to steal the vehicle. I would recommend it for use with most vehicles without difficulty, but did have trouble with my Landrover Discovery four. It was some time before I could get the clamp onto the wheel as the Y-shaped part would not click into the straight yellow part. I eventually managed to fit the device by taking off the two studs on the Y segment, when it could just connect with the last hole on the Yellow part. I emailed SAFE afterwards and asked if the studs had to be in place. They quickly replied with the answer that the studs could be left off and they asked me to send measurements of the wheel to them. I am sure they will have taken note of this and will make the necessary changes to the clamp to ensure there is no struggle in the future.

This clamp is very sturdy and well built. I wanted a clamp that looks like it will be difficult to tamper with and this fits the bill.

I use this clamp every day as it is fitted to a working vintage van that has no security . It is quite heavy so some people have difficulty putting it together.

The main issues we have are getting clamp over tyre with very limited room in wheel arch and then lining up the key bolt with one of the holes in the other side . Could have done with some markings as this is the hardest thing to do.

You are supplied with two keys but I got extra which is easy to do.

All in all a good purchase.

It does what it says - sturdy and strong. A great deterrent. Takes a bit of getting used to when putting on but it gets easier. Easy to take off.

A very solid and well made wheel clamp, straight forward to assemble from new, but a little tricky to line up when fitting.

Once on it is a very obvious deterrent to thieves and looks the part.

Very pleased.

Exactly what was needed for the job. Very solidly built, easy to install and unistall, fits well to the wheel and provides a strong visual deterrent to anyone thinking of trying to steal our vehicle. Would certainly recommend this product to secure and protect your car or motorhome.

Having tried and failed to convince a well known high street auto supplier that the product came in 3 variants, Safe supplied the correct version on line aand delivered to the door in minimal time. The product is professionally manufactured and simple to use. I would recommend the DC400 to any Motorhome user and Safe to any potential customer.

It was a little tricky to fit at first but now I’m used to it’s quite easy to use. I purchased it to protect my motorhome that I park on my drive. An excellent deterrent, and very sturdy construction gives me peace of mind.

Strong, robust deterrent on my motorhome. Find it a bit heavy and awkward to fit by myself but with the wife helping it’s not a problem. Old mans problem rather than product fault probably
