Wheels For Storage Cubes
I bought 4 kits of closet-storage cube drawers. Only 1 cube is assembled, and it's been sitting on a dolly for about a year.
The drawers are something like this, except they are single cubes, not the double wide cubes shown in the picture:
I don't have handy the weight of each cube.
The dolly is a metal thing I got at Staples a number of years ago. I don't know what weight rating it is, but it is meant to hold file boxes (paper files). It is expandable, and I have it contracted to as narrow as I can get it. The one assembled cube is sitting on about 2" of metal front and back, but I can't contract the dolly any further, so the left and right sides of the cube are sitting on the front and back of the dolly - the sides of the dolly are not under the cube, they are just left and right of the cube.
One of the reasons I haven't assembled the other 3 cubes, which will stack on the already assembled cube, is that I can't decide on the wheels. Should I leave it on the dolly? I bought a set of wheels marked light duty - I'm not sure if the combined carrying weight of the 4 wheels is 50 lbs or each wheel can carry 50 lbs. The problem with them is that I'm concerned about drilling holes fairly close to the edge of the cube. Both the dolly and the wheels are able to move freely in any direction. I don't really need to move the stack of cubes much. Forward and backward would do fine - I just need to roll it out of the closet about 4 times a year in total to dust under it and to access seasonal things stored to the left and right of the the stack. I've seen self adhesive wheels with a carying capacity of a combined total of 250 lbs. $14.99 seems like a deal considering I don't have to drill. They don't look like they swivel the way the dolly and wheels I bought do, but I don't really need them to.
So, any opinions? Dolly, wheels I bought, stick on wheels?
