I routinely use aluminum legs with double adjustment in portables. The current track at DH has my frames, but the PVC legs were by others - it kept the costs down a bit and since the floor at DH is relatively level in that area, adjustment was not a problem. The old location near the pool required leveling due to variations in the flooring. A plug in the bottom of the leg drilled and taped for a1/2-20 or larger bolt can provide up to 1.5" or so of adjustment. For outdoor tracks, the bolt holding assembly was also adjustable by a slide/groove/and tightening bolts to give up to 6 or 8" of adjustment. the extra milling, drilling, taping, etc significantly increased the cost of the legs. Keep your steam up! Walt Hope I have not created an affront with some of the readers by the number and length of my replies on this topic. But it obviously is a topic on which I have spent many hours of thought, and created some scrap aluminum, in the process of getting a workable system. Keep your steam up!
