Benefits of the Manticore Pre-Builds

    Customization is great and all, but it’s a lot of work. Heck, choosing what to eat for dinner is next to impossible. Meet the lazy efficient solution to the ultra-customizable Manticore Power Rack. We’ve done all the hard work of selecting features and putting them together so you can just pick, click, and get done quick. Take-out, anyone?
    The road less traveled is sooooo overrated (sorry, Robert Frost and high school English teachers everywhere). Why reinvent the wheel if our favorite proactive B.o.S. customers have already figured everything out? Each prebuilt Manticore rack includes the fan favorites and top picks (say hello to your top-of-the-line safety straps, pal), so you know you’re getting the best of the best.
    We get it. You’re busy. You have lots of Important Things™ to do (doom scroll through TikTok, for example). Well, we’re not allowed to waste time on TikTok at work, so we’ve used the free time to make this super convenient, time-saving option for you. Better yet, you know exactly what the cost is, so you don’t discover at the end of an enthusiastic clicking spree that you’ve customized a champagne rack on a bottom-shelf budget. You’re welcome.
