Are you able to screw these through the middle to attach them to an item? (I am hoping to replace the existing suction cups on my bird's bath perch).

I guess you could..They are actually on my boat right now, so I can't see them at the moment. But they are probably soft enough that you should be able to put a screw through them. All I know, is that I have bought numerous suction cups over the years, and nothing compares to these are far as the suction..

i doubt it....it may keep the cup from being airtight which could result in a failure to suck

Yes, that's the way I assembled mine. I believe they are screws meant just for this sort of plastic. I've had no issues with mine since installation.

Yes, the are sold here on Amazon, I recommend using some super glue on the suction cups to keep them firmly in place.

I would probably be able to attach them with hardware. If you want them to connect and match perfectly without any work, maybe not. Although, they might line up next to each other. Good luck to you.

Yes. It doesn't come with the hardware for that but you can buy a screw in hook. Very simple :)

That's exactly what I did. Of note: Keep in mind that these are light and move easily. So you'll need to strap them together. There are brackets out there, but I found zip ties did the job for 1/50th the price and you can't see them. Cheers!

Hi Paul, They are already attached. Make sure your window is very clean and that the suction cups are damp (not soaked) and press. It's a great bird feeder!! (deb)

I do not think that would be easy to do. They are designed to be mounted by sliding the unit onto screw heads protruding from a flat surface.

There are no hooks or holes for hooks on these. They are made to push into a hole and hold glass on top, as in glass top coffee tables. No real suction power like a deep dish cup would have.

They are plastic so I'm sure you can. They come with a hole through the thicker end already.

You will need to buy the "S" hooks separately. Here is the link to the ones I bought- they fit and work perfectly (http://amzn.to/1iiupEb)

They work great for holding old glass tube TV's on stands to the wall. It attaches to the item you want to attach to the wall with think adhesive on nylon straps. I dont think they could be depended on to hold onto a smooth glass aquarium weighing a hundred pounds with water. I would not do it. The other end attaches with wood screws in studs. Though it would be better than nothing, I would not trust it.

Yes, they can. I've got mine attached just that way. Make sure your swivels are large enough, must be at least 1" wide.

There are 2 ways to attach these: with screws or with the provided 3M double sided glue tape. So unless you want to use neither and use your own velcro, the answer is no.

The bottom of the shoe mount is female so you would need a 1/4 20 set screw to attach them together.

I haven't tried that. but if they're the same width it should be OK. You might need to tie them together with cord or twist ties, depending on how you're using them.

They have to be screwed in. I would inquire about proper screws for vinyl. Good luck!
