Question: How much do they weigh when filled with water?
Document: Very handy to weigh down the legs of the EZ set up tents. I wouldn't trust the plastic clips to last too long. I used sand and pebbles as I can see if filled with water, it would leak if tipped over.
These have better aesthetics than black nylon weight bags or effective but ugly concrete-filled 5-gallon buckets...Portable tents are subject to cover and frame damage if high/moderate winds &#34;launch&#34; or topple the tent. Filled with water, these weights will help hold the tent down and not take up too much space around the canopy legs.
Absolutely love these tent weights. Got them for my 10x10 canopy I use for craft shows. Filled them up with sand. They weigh about 18 lbs each. Very secure! Had strong winds and crazy weather, and the canopy stayed put! A little heavy when transporting but I think that's a good sign:)
Very easy to use and put away. The beauty of this is that if you weigh them with water, they're really light and manageable once they're emptied to put away.
Not all the weighted feet held water so the tent had to be put up with the normal anchors. Fortunately the ground was sufficiently soft to do this and there was not much wind that day.
We really like these weighted feet for our tent. We have used water so far, but will try sand soon also. They go on so easy and are easy to carry with us. Thank you so much
This is a great way to weigh your gazebo down without looking tacky. This was an excellent buy for me.
I filled them with water and they worked splendidly. They were incredibly useful for my wedding tent and didn't lead to any stubbed toes ;)
Also, we filled ours with sand, not water. I just noticed the price has dropped too, great buy! Say no to concrete filled coffee cans :-)
These things are fricking awesome. Filled with water they held my canopy down nice and looked neat. Like lil booties! Other vendors were asking me where I got them from.
Answer: yes
