Bev - the metal weights that I like and use are homemade.
Here is how we made them.
We had the local steel yard cut two-inch square steel stock into
24-inch sections. Buy eight pieces.
Trim off the sharp edges with a hand held angle grinder.
Purchase heavy eyebolts and nuts from your local hardware store. We
used 0.25-inch bolts. Also, purchase s-hooks to attach weight to
Then using our drill press, we drilled a hole that is a bit smaller
than your eyebolt.
Tap the hole to match the threads on your eyebolt.
Screw a nut on the eyebolt, screw the bolt into the hole, and
tighten with the nut.
Remove grease with soap and hot water. Then if rusty, spray with
duro-extend to convert the rust. Then paint the steel with rust
preventative paint, we used grey Rustoleum.
Attach substantial s-hook to eye bolt by squeezing one end closed
around the eyebolt hole.
I use two weights per corner, suspended on substantial chain, which
is in turn suspended from the upper corner of the tent with a very
To keep the weights from moving after suspended, I tie each one to
the tent leg with one of those elastic cords with a ball on the end.
We used two weights per corner to reduce the amount that I have to
pick up at once. The steel weighs about 1.1 pounds per inch with
2-inch stock so each weight is about 27 pounds.
The bad news is that steel is over a dollar a pound. The good news
is that these do not roll, they do not show much, and they really
weight down your tent. Being so dense, they don't take up a lot of
room in your truck or trailer.
This type of weight was originally available commercially but I have
not seen them in five years.
