## Description

Color: BlackWidth: 1 inch, Length: 3.28 feet Actual use length：1.64Kindly Remind: Not mated, The total length of the product is 3.28 inches, which is the length of one piece of material. Because two pieces of material need to be overlapped to use, the actual length used is 1.64 inches, so please compare the length to be used before buying The 3M mushroom buckle is composed of two plastic backing materials. There are mushroom-like plastic protrusions on the backing material, which is the mushroom head. When the two pieces of the mushroom buckle are pressed together, the mushroom heads will lock each other and make a ling sound. Steps for usage: Steps for usage:1. Thoroughly clean the surface of the adhered part, remove oil, water and dust, etc., and wait for it to dry2. Please use scissors to cut two pieces of tape of the same length with scissors as needed3. Use scissors to take two pieces of mushroom buckle, recombine and determine the sticking position, and then tear it apart4. Tear off a piece of buckle release paper and stick it on the surface to be pasted, then tear off another piece of buckle release paper and stick it on the object, pressing back and forth for 2 minutes.5. After standing for 24 hours, reclose the mushroom buckle Note: 1. The recommended working temperature is 20-38℃, and the workin temperature after bonding is -40℃—93℃ 2, 3M double-lock tape is not obvious to the touch after tearing off the release paper. This is the characteristic of 3M glue. It needs a certain amount of force and continuous pressing to release its stickiness. It is recommended to stick it for 24 hours before making it heavy 3. Do not hang valuables, fragile and dangerous items, so as to avoid improper operation and fall to you and cause loss and inevitable.

Review: Great, super grippy tape. I use this to hold a somewhat large hotspot in place in my car. It firmly holds the device in place in an area subject to high humidity and large temperature swings. Yet I can easily remove the device when I need to. I also use it to keep a battery pack attached to the hotspot. One caveat: as good as the adhesive backing is, the grip is perhaps even stronger. So don't use it on drywall or other non-solid surfaces unless you intend to keep the item permanently in place.
Review: A must have. Hold very well. Very useful when you want to avoid screws or nails like in a RV/Motorhome. Super fantastic product from 3M. YES recommend 100%

## Questions & Answers

**Q: What's the difference between this item and 3m dual lock 250/tb3550?**
A: That's a solid question, the difference is that there are slightly different variations of the stem and it's density.  There's also a difference in the adhesives used throughout the 3M Dual Lock. 

My observations are that the clear seems to hold better than the black, especially if you have to reposition it once adhered. That's all I know, hope it helps.

**Q: will this work on a bed rug truck liner?**
A: It would but weatherproof carpet tape or an adhesive tape made for this purpose might suit you better my friend.
You have to remember that two thick pieces of this will raise that area, all weather carpet tape or bedliner tape is fairly thin, and lays perfectly flat.
