Our uprights are made from 11-gauge steel, the gold standard of our industry. Strong enough to withstand 1,000 pounds, you will never have to worry about your rack shaking.
We use standard 2-inch spacing from hole center to hole center. You will not have any problems adding attachments or building onto your rack with other equipment also using standard hole spacing.
Choose from either a traditional powder-coated black, or a sleek stainless steel. Two amazing finishes, same unmatched quality.
Whether you're looking to upgrade your rack or build an entirely new one, Fringe Sport is now offering the same uprights used on our Dane 2.0 in singles and pairs.
Every great rig starts with great uprights. These 89-inch 3x3 uprights are the literal foundation of your setup.
Our uprights hit the height sweet spot for standard garage and commercial box ceilings. They're tall enough for pull-ups, bar muscle-ups, and wall balls, without eating into the 2 or 3 inches of clearance you actually need between the bar and your rafters. And because they're in line with our open ecosystem philosophy, any attachments from any company designed for 3x3 racks with 1-inch holes will find themselves at home on our uprights.
Buy one to replace a damaged upright. Buy a pair and add a section to your existing rig. Or maybe you've been dreaming of an all stainless steel Dane 2.0? Whatever your plans, our uprights will get you there.

The Mammoth works out of the box with the lever arm and the belt, which comes free. That said, most owners add the Kickstand. It holds the arm up so you start every rep standing instead of picking the weight up off the floor.
That's why we sell it bundled. Pick + Kickstand & Magpin, or go all in with + Kickstand, Dual Mounted Weight Horns & Magpin. Bundling at checkout costs a lot less than adding the pieces later.
We'll be straight with you. Every lever arm moves in an arc, so you feel less than the full weight of the plates loaded. The fix is length, and the Mammoth's lever runs 39" to 48.75", one of the longest you can buy. A longer lever means a flatter arc and less forward pull.
In our recommended setup you feel about 80% of the load, and up to about 90% with the horn moved closer to you. Most lever belt squats top out around 60%. A standalone machine costs $2,000+ and eats floor space. The Mammoth hangs on your rack. See the full felt load breakdown.
Yes, and watch it before you start. It covers the belt squat and the kickstand. The bolts are big, so have a large wrench or socket set handy.
One tip owners have flagged: don't skip the big washer that goes under the weight horn.
It fits 2x2, 2x3, and 3x3 uprights with either 5/8" or 1" holes. Just pick your hole size at checkout. The one thing to check is that your upright has holes on the side, since that's where the Mammoth mounts.
No side holes? The Wall-Mount Accessory gives you a dedicated belt squat station without tying up your rack. And if it still doesn't work out, you're covered by our 365-day no-drama returns.
Wall-Mount Accessory View Yes. The arm has about 10" of length adjustment, the horn moves, and you can mount it at different heights on your rack. Mount height matters most, especially for shorter lifters who need to clear the kickstand. Our mount height guide walks you through it.
Sharing with someone a lot taller or shorter than you? Dial in a setup for each of you, then switch mount height and arm length between users.
The Mammoth is rated to 900lbs, so the frame isn't your limit. Plate space on a single horn is. Add the Dual Mounted Weight Horns for more room, and they double as handles mid-rep.
Worth knowing: dual horns sit farther back, so felt load drops to about 65%. That's great for big numbers, but run the math before you chase a plate count.
Dual Mounted Weight Horns View The lever arm has a lifetime warranty, and the whole unit is rated to 900lbs. Check that your hardware is snug after the first few sessions.
The belt comes free with every Mammoth. It's padded so it doesn't dig into your hips, and it has 3 sets of D-rings on each side for a small, medium, or large fit. It's covered by a 1-year warranty, and plenty of owners use it for weighted dips too.
Yes. It sits at an angle when it's down, and a spring-loaded lever locks it firmly in place. It's 17" tall, so you start every rep standing and set the weight back down when you're done.
Kickstand View You can, and plenty of people start there. Here's what you get with the Mammoth: a 900lb rating, a kickstand so you start standing, a long adjustable lever, a lifetime warranty on the arm, and a padded belt. It mounts and comes off in seconds. No lumber runs, no guessing if it'll hold.
The horn takes Olympic plates and gives you 14" of loadable space. Iron or thin plates fit the most weight and give your knees the most clearance. Thick bumpers work, but they fill the horn fast and can crowd your stance. Standard 1" plates won't fit.
No rack? The Wall-Mount Accessory turns any solid wall into a belt squat station. Mount it into studs, never just drywall.
Can't drill? Owners also run the Mammoth on squat stands and yokes, as long as the uprights have side holes in 5/8" or 1".
Wall-Mount Accessory View Lookalikes can copy the shape, not the lever. The Mammoth's 39" to 48.75" arm is what gets you up to about 90% felt load. You also get a lifetime warranty on the arm, a real support team behind it, and hundreds of owner reviews. Garage Gym Reviews named it the best budget belt squat for a reason.
At 32lbs, one person can handle it. Hold it in two spots when you lift it off so it doesn't flop to one side.
Want to skip that step entirely? The Swan Neck adds swivel mid-rep and lets the arm store vertically, and the Wall-Mount Accessory gives it a permanent home. Either way, it never has to come off.
89-inches is the most common upright height for garage gyms, and gives the most function without being too tall or too short.
Both options are available. Buy a single upright if you're replacing a damaged one or adding to an existing rack. Grab a pair if you're starting a new section or building from scratch.
Powder-coat black is our most popular option. It looks sharp, resists everyday wear well, and is easier on the wallet. The stainless steel option is actual stainless tube, not a surface treatment. It's completely rust-proof, which matters if your gym is in a humid climate, an outdoor space, or just somewhere moisture gets in. It's a bigger upfront investment, but will weather the elements better over the long haul.
One thing to note: stainless steel 3x3 uprights from all manufacturers will always be roughly 0.5-1mm thinner than a powder-coated upright. This is because there is no additional coating on the stainless steel tubing. This does not change the function, but there may be some additional play with certain 3x3 attachments.
If your existing setup uses 3x3 uprights with 1" holes, these will integrate seamlessly. They're built to the industry standard dimensions.
The upright(s) only. J-cups, crossbars, spotter arms, and other attachments are sold separately. Bolts and nuts are also something that will have to be picked up separately.
Our uprights are picked up and delivered via UPS. Standard shipping applies.
