Question: Can you buy just the plastic sleeve.
Document: This is not a hard task, but does take several minutes to untie, pull, and retie the sections of line- Not a big deal, but the plastic sleeve comes with a plastic cap attached by a flimsy piece of plastic connector. The cap came off right away and is missing in action. Not a big deal, but poor design on a non-essential piece.Overall, this is a good buy. Functional, and well-constructed.
This Umbrella-style clothesline arrived quickly and in good condition. It was an easy fifteen minute job to dig a hole and mix a bag of Quick-rete (right in the hole) to set the plastic sleeve. Once the sleeve was set aplumb and the concrete dried overnight, the clothesline was slide into place the next morning. The line was ready for use right away.
I used a 15-gallon black plastic tree pot to install this clothesline. I followed the directions as if I were putting it in the ground, put the gravel in the bottom, did the sleeve thing, filled it about 2/3 full of cement, then topped it off with potting soil for plants. It's cute! We actually used a water bottle to protect the sleeve from dirt and water.
Ok, this is one that needs full disclosure. First of all, there is a weight restriction equalling about one basket of wet laundry (what else would one hang on it?). Next there is the matter of securing the sleeve in the ground with concrete (not included). Dig a hole, put in the very nice plastic sleeve complete with cover, pour wet concrete around it and use the dryer the next day.
We decided to make the clothes line more permanent and since we live in upstate NY we were a little concerned about using the "plastic sleeve" in the ground fearing it might not hold up so followed the manufacturers instructions reference the hole and cement but used a piece of old fence pipe slightly longer than the "sleeve" that came with the clothes line and just slightly larger in diameter than the actual clothes line pole.
This unit was identical to the one I replaced. Got 18 years of good service out of that one, even after a tree fell on it. A word of caution, the plastic sleeve they provide to encase in the cement will seize eventually and have to be cut out. This time I used a 12" piece of PVC buried in the ground. Works great. I did like the reviewer's idea of putting the clothsline in the patio table.
I love this clothes line. It was so easy for us to put up (we actually already had a hole from pulling out a bird house) we just sliped in the plastic sleeve and stuck the pole in and raised the arms. This can hold 3 large front loader washer full of laundery (that's 6 regular top loader washes) easily! We have not had any problems with this. Haven't had it long enough to see the power discounts yet but I know we will this next month.
To fix this, we drilled some holes in a piece of wood and stabilized the arm with a piece of wood,after that it worked fine. But soon after the dryer blew over in the wind again and cannot be repaired because the plastic arm connectors cracked this time. So, I would recommend cementing this into the ground if you live in a windy place. For 30 dollars, I think that this is a good buy if you don't treat it too roughly.
It works great and was a breeze to out it.. Need to buy more clothes pins now...same place I will go.
Best deal I could find, and it works very well. I have absolutely no complaints from this purchase! Would buy again
Answer: I never saw a sleeve when I purchased it.  Ask the distributor
