What keeps the tiers from sliding down the tube? Just don't want any accidents!

The tubes lock into the tiers. It is not one long tube but two separate ones. This way you can use just one or all and arrange the different sizes as you prefer.
933806
There is a knob on each of the flat plates that are inserted into the tubes therefore with the knob being wider than the tube it can't slide through.
933807
There are two separate pieces of tube that connect in between, so there's no sliding or height adjustment possible.

The plastic piece does not have a doube sided opening so it serves as a stopper.

There are 5 pieces in total so you have two pieces of the tubing that fits snugly into the tiers so it's solid once assembled

They have plastic tubes that slide into the holes of the tiers. They're sturdy

Go to the pet store and buy 2 bags of aquarium rock and pour it into the rails (they have caps to close it) fill as much as you could and this will prevent the stairs from moving.

The v shaped holders on the bike rack arms prevent any damage to the bicycles cables running under the top tube, so no need to worry. If for some reason it doesn't work well for you, then return it and give it one star lol.

Maybe, these things happen though with this tubing but a little more scary with an arrow in it for sure. Try to wipe off the end with a little alcohol and also put a drop down the end of the tube then rub a q-tip or twisted piece of tissue with the idea being that it will help remove any oils from ones fingers that might cause slippage. The without touching the area you cleaned push the tubing back on. If it is hard put a drop of water (yes, a little spit is just fine. Lol) on the tang to help slide on. If this is going to work it seems you would know right away but perhaps wait 30 minutes or so for the moisture to lessen. Having had quite a few wrist rockets this is an annoying think that happens at times. I figured it would be the case and got a couple heavy duty replacements. These are beefier than the one included. I also think climate play a part in the life of the bands and storage in a plastic bag for something might be best. I think of how a rubber band gets over time. Mine works well and no problem with the band's yet although I have been tempted to swap them out. If going on a trip or walk in the woods an extra band would seem important. Only problem I had was the wisher biscuit started coming out so I used gorilla glue to secure it. I hope this helps you.

As long as you can seal the ends, you can evacuate it and it will not collapse at all. I bought this to replace the glass tube that I used for a physics demo where a penny and feather fall through the evacuated space. I've gotten it down to about 1kPa and had no trouble.

The tubes are cylindrical and friction between the metal tubes keep it from rotating. Mine only rotated during a hard sudden jolt while the gopro was attached to the end.

First, I'd like to say this tube is excellent ! No problem with seatbelt. I had the tube in the back seat and put two fleece pet beds inside the tube. So no gap, no arch . We traveled from Chicago to Toronto on a vacation. I put one more balnket to make sure they didn't feel bumpy. My three cats had no problem at all. Of course, I stopped every two or three hours to let them out for potty and water. At home, I leave the tube in their room, they sleep in the tube too. BTW, strap the tube belt to the head rest for safty reason.

No, this has screens that prevents anything from falling to the next layer. We use ours weekly and absolutely love it!

I have 2 15-17 pounders who use it. One top end of one cardboard tubes did break and I replaced it with PVC, this was fairly early on too, and I broke another myself when I fell and was foolish enough to grab it. So it could break under your smaller guys too if they use it a lot. Mine kind of hang off the platform as they go up and down which strained the tube. The third has been fine but it is jammed in the corner and partly under a small ledge so it has extra support.As for tipping though I have had no problems.

The location should not be an issue because the U-tube normally can swing and can be moved up and down. As long as the size of the unit is not significantly bigger. Roberto

Are you sure you have it properly locked in place at the handles? That's what keeps it from sliding.

The tube is pretty rigid yet flexible, I've done what your saying. You will need one hand on the tube to keep it from flexing under the weight of the 5 gallon can leaning on it

I found that the parts had to be inserted enough distance to stay together, but it was difficult for the tubes to fit into each other. I think I sprayed the tubes with something to allow them to slide together. I haven't taken it apart since then!

Hi! The underside is hollow with a strut in the middle for support. There are rubber pieces on the bottom corners(6 in all ) for non-skid. I have had no problem with our stairs sliding at all and Lewis is a hefty 60 lb. bassett hound. I hope this helped.

I extend the legs first and tighten nuts...this gives the stand some downward weight. Then loosen the turn knob at end of center post and the inner tube should advance freely. Sounds like there may be a dent or crimp in the tubing or a metal burr that's catching. I'd return for an exchange.

There are two rods that slide and lock in beteeen so that balls will not fall. You can travel without issues.

Yes, you would have to put a non- slip material under it to keep it from moving
