4Pcs Bubble Spirit Level RV Standard Levels with Mounting Holes RV Levelers Leveling Tool for RV Camper, Travel Trailer, Camping, Truck, Motorhome (Set-A)

Exactly as described put on both sides of the camper makes it easier to see and use. We got camper level first before putting it on of course

I had the same type levels on my trailer but they finally leaked after thirty years and these were a easy replacement and work great.

I added these to each side of our 2003 Viking Pop-Up camper. The adhesive is very sticky & has been holding up for over a year. They are a great value for the money, are very accurate & function properly. I was impressed with the size as well.

ONLY REASON FOR A 4 STAR IS I WISH THEY WOULD HAVE ADDED A DOUBLE STICK TAPE ON THE BACK. IT IS ALSO MY FAULT FOR NOT READING COMPLETELY.I HAVE ONLY USED THESE IN MY DRIVEWAY, BUT SO FAR I WOULD HIGHLY RECOMMEND

Checked them on a level surface and they all read correctly. Cheaply made overseas, but good value for the money.

I'm using this product for my sluice box to give it the right angle for the recovery of gold.Haven't attached them yet but I will have them setBefore I go out to use my new sluice box..

Came with both screws and adhesive tape.

I ordered these bubble levels to adjust my beehive swarm traps so they draw comb evenly. I mounted them to the swarm boxes and used a 4' long carpenters level to calibrate them. These need to be off level by a fairly large amount before the bubble moves at all. So if you're in need of something fairly accurate or sensitive to small adjustments these are not it. If +/- 10 degrees is close enough for you these will probably work just fine.
