3MBumpon SJ5023 Black Bumper/Spacer Pad - Square Shaped Bumper - 0.81 in Width x 0.3 in Height - 67388 [PRICE is per PAD]

இ Fuzzy Wuzzy's Summary:ѾѾѾѾѾ Highly recommended with warm fuzzies!I have purchased a variety of these kinds of stick-on bumpers for use in a wide variety of applications such as cabinet door bumpers and the back corners of picture frames. The clear "Bumpon" bumpers can be placed underneath crystal and glass objects to cushion the contact points between the glass and the table surface. The "3/10 in. thick x 0.81 in. wide" bumpers that I received were shipped in a clear Ziploc bag with no "3M" brand label on it. When I first opened the Amazon box, my first reaction was that it resembled a bar of dark chocolate :-) and there are 36 tapered squares per pack. For the 3/10-inch-thick bumpers, I have stuck them underneath the rear corners of some portable keyboards to increase the keyboards' tilt, underneath the rear corners of laptops to improve the efficiency of the fan intake vents located underneath the laptop by improving airflow under the laptop, and underneath external hard disk enclosures and other electronics. These bumpers have a pretty good grip on most surfaces so it also prevents the object that it is stuck on from shifting or sliding around the surface.As befits the 3M brand, with their line of Scotch Tapes, these bumpers really stick on tightly and do not loosen up later on. I have previously used adhesive-backed bumpers/feet that either stuck on too loosely, or appeared to stick well initially, but then detached after awhile. When sticking these bumpers on, it is very important to stick them onto a clean dry surface; i.e. no dust, dirt, or fingerprints should be on the surface. So thoroughly clean the surfaces where you will be sticking these on, and be careful and precise when you press them onto the surface so that you do not need to lift them up and readjust them again due to errors in placement.The polyurethane that is used in these bumpers are plasticizer-free, which means that you do not have to worry about having plasticizers leach from the bumpers and possibly staining your walls or flooring.These bumpers are fairly firm in density. If you need rubber bumpers/feet to place underneath loudspeakers, subwoofers, turntables, or other items that need to be isolated from vibrations, a better, but more expensive, solution would be to use the "Sorbothane" bumpers. Sticking four 2.0" Sorbothane bumpers underneath each speaker or subwoofer can especially dampen the bass vibrations that are coming from the speakers and transmitting the sound across the floor. But unlike these 3M bumpers, the "Sorbothane" bumpers do use a plasticizer that can potentially leach onto a surface or flooring and possibly discolor wood as a result. But you can insert a piece of plastic wrap between the Sorbothane bumpers and the surface that they are resting on to prevent any leaching risks.

I have been very happy with these bumpers and have already purchasewd them a second time. I use them mostly as "feet" on the bottoms of electronics and similar sized objects. My primary goal with these bumpers is to prevent the devices from sliding around and scratching whatever table/desk/bench/glass case they may be sitting on. For this function, they work very well. But as one reviewer wrote, these bumpers are fairly hard - with not much cushiony "give". Consequently, such bumpers might be noisier than you would care for in applications -- such as like cabinetry -- where the bumper would be in frequent/daily use as a "stop". You might want to consider something softer if noise could be an issue.At work, we have an older computer that is shoe-horned into a very small space. We had to use a short piecce of 2x4 to prop the rear of keyboard up at an angle in order to it to fit in the space allowed. But it kept sliding off the shelf -- onto the floor. I placed 5 of these bumpers in a line under the rear of the keyboard so that they would all rest on the board. Problem solved. The keyboard stays exactly where we put it.Finally, if you use electronics in areas prone to liquid spills, these little bumpers will lift those devices high enough to stay out of the way of most minor spills.... making these bumpers very inexpensive insurance policies.

Make sure the surface is clean, clean, clean, and they won't come off. The polyurethane material is durable yet soft enough to absorb vibration and keep them from sliding around (on clean surfaces at least). The adhesive is really good, but requires a perfectly clean surface, and a short period of firm pressure to ensure adhesion.

We use this product to mount cash drawers off of the counter so there are no scratches. In our case this item comes with 36 individual (rubber feet). The adhesion, once attached, stays very well. Each square can be purchased in different sizes, and the bigger sizes come in fewer EA counts. The single (foot) once applied sticks very well with the 3M backing removed. This has been a staple in our business for years.

I love these. The adhesive lasts and the bumpers themselves are big enough to hold up substantial appliances. The rubber has only a small amount of flex and isn't sticky to the touch. So far I haven't had any issues with the bumpers sticking to the countertop as with other varieties. These add about half an inch, which for my purposes was critical. I needed enough space for some cooling airflow under the appliance, and smaller bumpers didn't cut it.Remember to clean and dry the area these will be attached to thoroughly. If you have trouble with them sticking poorly, try using some sandpaper to rough up the attachment point, clean, dry, and reattempt.These are great, and you should buy them. Just check the measurements against where you want them to go, because these are larger than what you commonly see on devices out of the box.

These are terrific for providing non-slip, protective feet to various items. I ordered them to protect my desk from a standing-file organizer that didn't come with feet - not only could it scratch the desk, but it also annoyingly moved around when I was using it. These bumpers are extremely protective - and things will NOT slide around. They're not sticky, per se, but they certainly will not slide. I thought I only needed 4 of them for that one item - but very quickly found about 5 other applications for them - might need to order more. The one question I don't see an answer to - will these deteriorate over the years, and leave a residue or mark on wood surfaces? So far - zero issue.

Taller and larger rubber feet to use in place where you deem equipment manufacturer provided rubber feet are too small. Example, MRV LX-1004T terminal servers (small squares), Palo Alto Network's PA-200 (round and short), etc. The glue/adhesive is not strong so don't use your own glue if you require gorilla strength feet. For those wanting feet for Samsung T5 SSDs (no feet provided) these are far too large so those boxes should get small rubber feet :-)
