it is necessary to use the brackets? or I can use it for friction?

While it may work using friction, it did fall on my a few times. I highly recommend using the brackets if you are afraid of falling.

yes you can. It comes with all the needed brackets and screws in order to do that.

It should not need brackets since it is quite sturdy when installed in the ground up against a wall, but brackets may be purchased at a hardware store if you wish to do so.

That is a great question. The metal brackets are not thin. I use it to hold my laptop. I wish I could be of more help.

Yep. Just be sure to tighten everything down well before you get started ... those thumbscrews can come loose under vibration.

Hello. Given the intended application, I would not recommend this bracket. It is a great product for to home or office, and it could work well under smooth driving conditions. I can however see a scenario were hitting a large pot hole may mimic the removal action.

I think you can do that. maybe rigging up some extra support using an L bracket

It comes with a pair of brackets....depending if you wish to mount permanently or not.

You will need to purchase brackets separately. They are inexpensive and available here on Amazon.

You don't need bracket. They should be holes predrill to your bumper, use two screw to hold it in place and it shouls be tight.

This unit can be used both ways. If you door mount it you have to purchase the brackets separately.

There is a bracket included to do that but I didn't use it, the bookcase it very stable without it, if I still lived in Southern California I probably would have.

Not sure what you mean by brackets. I didn't get a counter balance weight so as to be able to even out the weight when I put on the shaft. If there is something that the picture shows that you didn't get you should contact Amazon or the manufacturer

Yes you will have to drill holes to use the brackets provided however we did not use the brackets just tightened it I between the doorway like you would a shower rod which doesn't do any damage to the wall and it has worked perfectly and not slipped at all.

I don't believe so. I had to use adhesive to mount mine. I do love it though. I don't quite understand how the brackets work.

It depends on the width of the handlebars. I actually mounted a piece of wood on the wall to span the distance of a few studs, as to not have the positioning of the studs dictate the spacing of the brackets. The you can mount the brackets whichever distance you want from each other, and not sacrifice support.

No, these are used to add a footboard to a frame that doesnt have the brackets already to do so.
