Question: Does this net come with a center strap?
Document: Purchased with the Macgregor center straps.
This tennis net does not come with long enough cable to fit the standard doubles court poles. I have to take out the cable that come with this new net, take out the old cable from the old net, and install the old cable into the new net. I could have returned it, but once you opened the net, very difficult to pack it back to ship. So, a simply 15 minutes installation process takes me about 2 hours.
Installation difficult for us because the poles are old and do not have a crank handle but it's a great net.
Good net at a great price. Bought this for the court at our home owners association. Looks great and hopefully will last a long time.
I am very satisfied, the old tennis net has a vertical aluminum rod at  each end,which I think is good for the net looked straight at side.
As expected, my only complaint is there are no poles in the ends to pull up to the end posts to stretch the net its entire height, but it's very good quality otherwise and looks good.
I have to use a rope to tie it down.The price for this net is good. But the next time I order a replacement net, I will go for a different net with longer cable, even if I have to pay a little more.
After FIVE weeks I realized that they actually meant to do NOTHING. I was forced to purchase another headline wire. Net World Sports will say anything to please you and do nothing to follow up. This is the first negative experience I have had on Amazon and by far the most miserable experience I have have ever had shopping online.
This tennis net has been a fantastic purchase, the quality of the braided netting is truly unmatched from my experiences with previous tennis nets. It has endured all weather conditions that we have left it out in, including wind and rain, and still looks very neat and strong.The headband notably has not torn - which is always something that has happened early on with our previous tennis nets.I think I am right in saying that this is the same tennis net that is used on Centre Court at Wimbledon.
The quality of these 3.5mm double top nets from net world is better than any nets we've seen or used. The braid is so dense and over quality is that high we've order these nets many times for our 16 court facility in Oakwood. What's more, they always seem to arrive within 2 days of ordering. If you want quality these are the nets you want. They are better than any mcgegor or Edwards net we've used as well.
Answer: yes
