Our school wants to let 300 cars to use 4 curb ramps each time. Is it strong enough? How to connect 4 curb ramps? Do I need to buy mounting sokets?

Yes they are easily strong enough. Each ramp comes with two bolts and two nuts to connect them side by side so you do not need to buy mounting sockets.

You may need a ramp extension added depending on the height of your van threshold. Pinning isn't usually necessary if you have a good fit and the angle is well within the recommendations. Ramps are very well constructed and not as EASY to move as the lighter less strong ones. Pinning will make you feel much more secure and give you peace of mind. We have a Chrysler T&C; and do not need to pin at the side entrance. The rear is just enough higher that it would need pinning. Ours would be utterly easy to do.

So I think the weight needs to be spread out. If there are 4 wheels then it can probably handle the weight. The thing I wonder about is width and control. The ramp is edged and the bed of the ramp is only 13" wide. Also, I think it would be pretty steep - could you keep control? I would take a tape measure and measure out the length, and then hold it up to the back of your truck and look at the steepness of the slope.

Very easy. If you only want to install two curb feelers, put one on the right front wheel well and one on the right rear wheel well just in front of the tires. Use Phillips screwdriver to tighten screws and adjust feelers out enough so they are lined up with the street curb.

Yes, you need four of these to anchor the base completely. You might get by with just two opposite of each other in less windy areas. Remember, this is designed for a specific base type, having edges that extend along the ground surface and long enough to fit under the edges of the wedges. That said, it is very wind-durable... from what I've seen, wind will more likely bend the umbrella pole before it blows over these weights!

I know others have said you could use them for a trike, but I can't see how! You need a third ramp for the front wheel if the two back wheels will use the separated ramps described here since only two come in a box. Each rated at 750lbs, though, and if putting more wt. than that, they may bend like others have described.

You have to be strong enough to lift your SUP over your car. With the handle on the SUP, you can put the nose of the board a on rack and slide it forward in order to avoid scratching the car. There is no easy way is your not strong enough.

I have found that a single unit is fine. In fact, it is much easier to install just 1 unit than trying to get 2 of them even (level) with each other. Just line it up with one of the front tires, and stick. Since most people are used to "feeling" for a cement block / curb with their tire, you can feel it when you rest up against it. I have 19 inch tires on my car and feel it with no issue, and also had no issue feeling it with our SUV. If you had a monster truck or something with really knobby tires, you might have an issue but otherwise its fine. I still love these things!

Hi Vega - The ramparts are just one part of the system. They attach to whatever material you want to use for the ramp. They're designed for dimensional lumber and this particular series suggests 2 x 8 lumber if I recall correctly (note - you need to confirm their recommendation and loading capacity). So....depending on your application you could use plywood depending on the load you will be applying to the ramps. I don't know what you're need is but I wouldn't feel comfortable with anything more than a push lawn mower or similar load. YMMV Good luck

It is very strong. I think you would be ok with that amount. For example I loaded 10 green four to six inch diameter twelve foot poles on my Chev Silverado 1500 by putting the butts on the bed against the tailgate and propping the poles up over the cab on the Backrack. I was more concerned about the truck than I was about the rack. Hope that helps.

The same company sells "kits" for building large ramp systems. These are pricey, but it might be the way to go.

The rack that is included with this board is made for a 4 door car. We have a minivan with sliding doors so the rack does not work at all because the straps that wrap around/under the roof of the car obstructs the sliding doors from closing. I had to make some major alterations to this rack and watch some YouTube videos to figure out the best way to put these racks to use, but you will need hard racks or crossbars on the roof of your car in order for this rack to be useful.

I'v got a Dodge 2014 4 X 4 and I use them to load a lawn mower. I'd feel safe loading about anything in the weight range. The adapters have a nonskid grip you attach and if ya look you also have two wholes on the surface to use set screws if you want( I don't think it is at all necessary). Someone also wrote that the boards don't fit. They fit just fine. They may be trying to use unfinished wood. The ones I got from Lowes worked perfectly. These are excellent ramp adapters. The instructions recommend a really long board for the height, but I found that not to be the case for a lawn mower.

I wouldn't think you'd have a problem ... ganged up, the weight disperses to all four wheels. I stack two Fender, 76 pounds each, 4x10 cabinets, and the Ernie Ball casters run smooth as a whistle. So the load easily carries 152 lbs. And, lots of times, I roll one of the 4x10 cabinets stacking my Fender Hot Rod DeLuxe on top... that's WELL OVER 125 lbs. One thing about any casters, though. I always PULL the cabinets (don't push), and when uneven sidewalk slabs come up, help the front wheels over the lip ... don't just push and crash then ... help it with a little lift. Nothing will hold up if you smash them around. My Bassman 135 4x12 cabinet has the same casters, too. I think you're easily good to go.

I don't know exactly how much it will support but it is heavy gauge steel throughout .... I step on the curves often and there is no twisting, it is very solid. And by all means get the one with the lights !!!

Yes. We use this to edge along a curb and have no problem, although you may have to go in one direction only.

I would say yes they will support it. I have never had a problem with these ramps. I use them to load my Honda recon 250...I ride it up in to my truck..I'm not sure of how much my 4wheeler wieghs , but I'm 240 lbs myself and these ramps have never even flexed on me.
