The quality and engineering details of the Sahara 52" above ground swimming pool surpasses pools costing much more. This pool is constructed with large 7" steel top rails and 6" uprights with Krystal Kote protection to guard against the elements for a stronger swimming pool and an easier installation, especially for the do-it-yourself customer. The Sahara 52" pool utilizes an interlocking steel stabilizer at the top of the pool combined with a hardware free "snap in" resin bottom boot. The ovals are engineered with the Yardmore buttress free space saver system. This pool has a 40 year warranty and is available in round or oval sizes.
