Question: Is the angle of the pole adjustable if the base can't be put on a completely flat area?
Document: I lined them up using the holes, which was wrong and had to pull the poles apart with the help of a friend, my Landrover and a tree, but other than that, I did it all myself. When i had the pole together and attached to the base, I laid the whole thing down to put together the backboard. It solidly took me about 7 hours to put this thing together.
I bought this product two months ago for my kids. They really like it and so far it does well. Assembly instructions call for two people. I definitely recommend that. I put it together myself and although the process is not difficult, some steps are much easier with two.My only complaint is with the base. I initially decided to fill it with sand for extra stability and because I live in an area with harsh winters.
I bought this set for my four year old grandson, just because. He loves it. It is adjustable and he will enjoy many hours outdoors playing.Although it took my husband and I hours to put it together.
We've had this hoop for about 6 months now and we're very pleased. I was hesitant about getting a portable hoop. Most of them aren't very sturdy. And, on the ones I've tried the backboards don't have a very good feel (bounce) to them. Much to my surprise, this one is excellent! The system is solid and the backboard feels nice. I particularly like how the pole is on an angle as it provides some extra room under the hoop.
Then, once that bolt is thumb tightened, remove the screwdriver and fasten the second bolt and tighten both down.One other note, be sure to carefully study on the instructions the orientation of the bracket that is spot welded on the middle portion of the lower pole. This welded bracket side should face rearward, away from the two wheels on the plastic base. The instructions did make an emphasis of this, but should have provided an even clearer graphic showing the situation.
Nevertheless, I chose to avoid using the plastic rebounder because I have a fence and back net that prevents errant shots from bounding away. The trickiest part of the assembly is mounting the main vertical pole to the plastic base. Once installed it is very secure. But, lining up the exterior metal plate, on the bottom of the plastic base, with the interior metal plate welded inside the bottom pole, is a bit tricky.
I too had the initial shock of opening the original shipment only to find out the backboard was cracked and literally looked like it had been played on for years. I purchased the 60" version but I'm leaving the note here. Amazon was quick to send a new one... That was the good news. The bad news is it took me about five hours to put together and after thinking the end was in sight my hoop is also slightly off-center from base to backboard.
Never write reviews but hopefully this will help someone down the road. Just finished putting the Spalding 68564 54" Acrylic Backboard system together,...twice. The first time I put it together I was sure that I made a mistake. Holes didn't align and the backboard was not parallel to the base. So, it's possible, I do make mistakes. Took it apart and did it again. BTW, the first assembly took 3 hours. Anyway, disassembled it and did it over. Same thing.
Didn't even get it out of the box before we returned it. The backboard is HUGE, and ugly. It's wide. If you are serious (and don't care what your driveway looks like) go for it. The box had been opened by the time we received it, meaning we are the second buyers (at least) to return it. We wanted it for a vacation cabin in a rural area so it cost $150 to return it (plus the original shipping).
It's like the pieces were close, but not precise. Having the dimples and the channels in the three tubes that form the main support pole all lined up, for example, will not ensure that your backboard won't be out of alignment at the end of the process. But perhaps the most frustrating thing of all is that if you call the 800 number to request guidance or replacement parts, you'll find no one there on a Saturday afternoon to take your call or answer your questions.
