I bought an open or sumo squat rack by TDS about a year ago. This rack is much shorter than a full cage rack, so it fits in the basement of an older house, or just one with low basement ceilings. It is rugged, can handle more than 500 lbs., and is fully adjustable from about a foot up to about six feet. It can be used to safely and effectively perform squats, rack pulls, and, by placing a bench inside, one can do a wide variety of presses. Just adjust the safety bars to the proper height, and you can work to failure on any set without getting buried.
