Product Summary

PRx’s Build Limitless Series gives users the freedom of starting small and easily expanding their home gym with two different expansion kits. The Full Cage Expansion Kit transforms the base model Squat Stand into Full Cage Power Rack making it possible to continually upgrade your gym space and fitness routine. Made in the USA, the Full Cage Expansion Kit is constructed with 3-inch-by-3-inch 11-gauge steel and coated in a black powder coat, making it both strong and durable.

The uprights in the Full Cage Power Rack Expansion Kit are available in two heights (81-inch and 95-inch) to match the height of your Full Cage and ceiling. PRx customer service assists buyers in choosing the height that works best with their ceilings. Both uprights and crossmembers have ⅝-inch laser-cut holes for endless accessory options. What’s more, the spacing in the bench area is 1 inch, which allows for specific J-cup placement for those bench press days.

While the notion of being able to add onto existing equipment to save money is really cool, let’s take a look at some of the actual numbers. The base Build Limitless Squat Stand sells for $599, and the Build Full Cage Expansion Kit will cost you another $749 plus shipping. All in, you are dropping around $1,500. With a quick internet search, you can find full cage squat racks from reputable brands for the same cost or even less. So, if your intention from the start is to have a full cage rack, this may not be the most economical choice. That said, if you do want to start small or live in a small space but may eventually have more, then the Build Limitless Full Cage Expansion Kit is a great buy.
