Engineered for true wide grip
Most doorway pull-up bars look long, but raised center locks and bulky hardware reduce the space you can actually grip. TB7 turns more of the bar into usable grip.
Grip where you want
Raised locks and uneven grip surfaces interrupt natural hand placement. TB7's patented center-adjustment system creates one smooth, uninterrupted grip surface across the usable grip area.
PCT/KR2023/018599
TB7 was built to remove the tradeoffs that make traditional doorway bars feel narrower, less natural, and less secure than they should.
Raised locks and bulky hardware cut into the space your hands can actually use.
Uneven sections force you to work around the bar instead of your body.
Basic pressure-fit bars can feel like they might shift, slip, or lose their seat under load.
The TB7 comes in two sizes to fit a wider range of doorways. Choose the size that matches your doorway width: Short Extension: 29.5–34.5" (74.9–87.6 cm), Long Extension: 34–39" (86.4–99.1 cm). Enter your measurement below to find the right size.
Choose the Long Extension size. It fits doorways 34–39 in (86.4–99.1 cm).
S.4-1
Traditional bars lose grip space to raised locks and bulky center hardware. TB7's patented flat structure removes those interruptions, so more of the bar stays open for your hands.

S.4-2
TB7 keeps a consistent 1.6-inch grip across the usable grip area, so your hands do not run into thin sections, raised locks, or awkward grip changes.

S.4-3
As bodyweight is applied, TB7's center-expansion structure helps press the bar outward into the doorway frame, creating a more confident hold during training.

S.4-4
Each TB7 size is load-tested to meet its specific design standard, giving you confidence before you put your bodyweight on the bar.

S.4-5
Patterned non-slip pads help increase contact with the doorway frame and spread pressure, giving TB7 a steadier seat without screws or drilling.

Set the width, check the level, then twist to secure. No tools. No permanent setup.
Extend the bar to fit your doorway and use the included bubble level to align it evenly.
Twist the center adjuster until the bar is firmly seated. Check the fit before every session.
Mount it high for pull-ups and core work. Set it low for rows, push-ups, sit-up support, and mobility training.

Answers to common questions
Satisfied, so I ordered one more and installed it at my parents' house.
rjsl****, KR
My husband works hard at it.

I bought it in the evening and received it the next afternoon. I bought it for my older child, but I think I like it even more. As soon as I installed it, I tried hanging from it, and it held my weight of close to 90 kg (about 198 lb) very well. I did it once, and it feels so refreshing, like my hunched back straightened out.
ne****, KR
My husband likes it a lot since I bought him this one.
mnh7***, KR
It installs sturdily and well.
bull***, KR
On the one I used before, the ends of the grips were uncomfortable, so I worked out holding it narrowly, and while looking for something else I bought this. The ends have a consistent thickness, so it's very comfortable to hold. The product also feels heavy and sturdy. I think I'll be able to use it well.

Installation is super easy and it's solid. Other ones I used before felt like the middle sagged and were weak, but this is very different. Sturdy and solid! Five-star recommendation!
cool*******, KR
The grip is good and it's very sturdy. My second daughter hangs on it every day, flying around. My third and fourth daughters also hang on it every month, saying it's cute.
ko****, KR
At first I hung on with my feet on the floor, but now I'm hanging with my feet off the ground. Even so, it doesn't slip down and stays fixed well.

I installed it on the doorframe and used to do pull-ups every time I passed by, so even one rep was hard, but now ten are possible. Thank you.

I already bought one and have been hanging from it for almost a year. I had very little arm muscle and no grip strength, so at first I could barely hang on for 1 second, 2 seconds... but these days I can hang on for close to 1 minute. Lately my mother has also had back trouble and even got treatment, but she said it didn't feel like it had really cleared up. Then she tried hanging from a pull-up bar at the playground and said it felt refreshing and good. So we bought the same pull-up bar we use and installed it at her house. She's working hard at it. I hope she keeps improving.
yune****, KR
It's sturdy and good. Thank you for the fast delivery.

It's easy to install, has a good grip, and is easy to use. However, the rubber smells a bit, but I think it'll go away as I use it?

With sturdy plastic and the middle twisting to widen, it doesn't look like it will shrink even without any safety pin. If you hang a level in the middle, you can check it every time you work out. If the doorway gap widens, the bar seems to lower a little, so I think it's enough to check it occasionally. Especially, the plastic looks sturdy and like it will last a long time. The pull-up bar is also light.

I bought a cheap one in the ten-thousand-won range before, and it smelled a lot, so this time I chose a proper product. I was going to install it on the door, but it seemed like the doorframe would spread apart, so I installed it on the back veranda wall. The height is also suitable and it seems good. Compared with the existing products, it is definitely heavier and gives confidence. I especially like the way it expands from the middle.
ei****, KR
It's installed sturdily, so I'm using it well.
kby_****, KR
The grip is thick, so it helps with forearm workouts, and I like that it has a snug feel.
1273******, KR
I like it. I like that it can be used as a wide grip.
skyd***, KR
I bought it to treat my forward head posture. I'm hanging from the pull-up bar every day.
jsm9*****, KR
Um... I'm using it as a clothes hanger. The product is good, and safe.
