We have what may or may not be a big issue - one set of uprights/straps is shorter from one side of the pool to the other than the rest by about 1/2" or so. Uprights were all lined up and installed evenly, but when the straps went on we ended up short. Pressure plates are installed and all went on correctly lined up. Blocks are in under the straight side uprights and channels are buried level with the ground.

The strap does not appear to be buckled up or heaved anywhere along the length, the uprights are level in all directions - not tipped forward or back, which we thought would cause the discrepancy. When we tried to move the one upright back to even with the other three, it pulled from the other side. Can this be a defect? How much of a problem will this cause when putting the bottom rail, wall, etc on? We plan to install bottom rail and curved side base plates this evening.
