Are you wondering why the prices on our website, khanhtrinhvn.com, are more favorable compared to those on Amazon for the same product? We can assure you that this discrepancy is not a reflection of the product quality but rather an outcome of different operational costs associated with each platform.

As a valued customer, we believe you have the right to understand why this is the case. When you purchase a product from Amazon, the price you pay includes a variety of Amazon-associated fees. These fees are necessary for us, as a seller, to utilize the extensive customer reach and convenience that Amazon’s platform offers.

However, when you purchase directly from our website, we can bypass these additional fees, allowing us to offer you our unique, high-quality products at a lower price. Despite the price difference, you are still purchasing the same excellent product from the same reputable manufacturer. Our commitment to quality and customer satisfaction remains steadfast, regardless of the platform you choose to purchase from.

Therefore, we encourage you to enjoy the benefits of direct purchasing from khanhtrinhvn.com. Not only do you get the best prices, but you can also shop with the peace of mind that you are dealing directly with the source. Remember, your trust is our top priority, and we are dedicated to delivering nothing but the highest quality products, straight from our manufacturing facilities to your doorstep

We understand that customers are always seeking high-quality products at affordable prices. Thus, our pricing strategy carefully balances between offering our customers a fair price and maintaining our business’s sustainability.

As a manufacturer based in Vietnam, exporting our products, especially heavy ones, to various countries, entails considerable costs, including shipping, customs fees, storage, and marketing expenses. These expenses prevent us from setting lower prices that would jeopardize our business continuity. Hence, we set our prices at a level that ensures the longevity of our business and upholds our commitment to providing high-quality products.

Despite this, we offer several ways for customers to avail of our products at a more affordable price:

+ Group Purchase: Organize a group buy with friends or family. We offer discounts for orders of more than two units. Please contact us for more details.

+ Repeat Purchase: If you’re considering buying our products again in the future, whether for personal use or as a gift, we offer discounts for repeat customers. Just contact us and provide your previous Order ID.

+ Purchase of Returned Products: Occasionally, we offer returned items at discounted prices due to their limited availability. Please contact us if you’re interested.

Answer: a) The similarities: 

They all have GREAT FEATURES of KT multipurpose folding stand frame

b) The differences:

+ Firstly, the most obvious difference is the way to adjust the handle-bar height. KT One-tiered folding stand frame has only 01 handle-bar, so you can adjust its height for taller user and shorter user as image below:

height adjustment

KT Double-tiered folding stand frame Model KT1.HT has 02 handle-bar, so you don’t need to adjust the upper handle-bar height when shorter users (such as kids, women, old people) want to workout. Just simply adjust the height of lower handle-bar by mounting it to the legs of frame at appropriate height level as image below:

adjusting height HT

+ Secondly, KT One-tiered folding stand frame can be folded in 10 seconds, but it takes more time to fold KT Double-tiered folding stand frame (about 35-40 seconds). Because you have to remove not only 02 lower distance-setting-bars but also the upper distance-setting-bars (which support the lower handle-bar) to fold the KT double-tiered stand frame

We have a “product comparison chart” on our homepage, just above the section titled “WHAT MAKES THE KT PULL UP BAR LOVED BY USERS ?”. For more detailed information, you can refer to it.

While the structure of Models KT1.1520 and KT1.1518 is the same, the main differences lie in their maximum load capacity and maximum height, primarily due to the larger and thicker steel tubes in Model KT1.1520.

+ Model KT1.1520 is significantly heavier. The weight of Model KT1.1518 is 35.27 LBs (16kgs), whereas Model KT1.1520 weighs in at 63.93 LBs (29kgs).

+ The maximum load capacity of Model KT1.1518 is 440.9 LBs (200kgs), while that of Model KT1.1520 is 771.6 LBs (350kgs). This means that Model KT1.1518 can withstand a short-term maximum weight of 440.9 LBs, including the user’s movements, without bending, breaking, or collapsing. However, in the long run, if users weighing over 220.46 LBs (100kgs) consistently use Model KT1.1518, it may cause the handle-bar to bend.

+ The maximum height by design for Model KT1.1518 is 89.37 inches (227cm), whereas for Model KT1.1520 it is 101.57 inches (258cm).

+ For Pull up bar exercise, Model KT1.1518 is suitable for users who are less than 5.9ft (180cm) tall and weigh under 220.46 LBs (100kgs). If you are taller than 5.9ft or weigh between 220.46 LBs and 440.9 LBs, we recommend using Model KT1.1520.

Answer: You can perform these actions after do some necessary protection methods (for safety) such as: put heavy things on the legs of KT folding stand frame (example, 4 sand bags, total weight each side is heavier than your body weight), ask 2 people to hold the legs, or drill and screw the legs to the ground… Because KT folding stand frames are placed on the floor without being fixed to the ground, and have lightweight structure (for easy moving, folding) so if you don’t do the protection methods but still perform these actions, it may be dangerous for you (the legs can be lifted off the ground and the KT folding stand frame may topple over).

Normally, you should only swing/fly in the area formed by 4 legs of the KT folding stand frame


Answer: You can place it anywhere you want. But you should keep it indoor to avoid rain and snow for long-term use. Because it’s made from Alloy Steel (main component is iron (FE)) , not from stainless steel (inox). All tubes are coated (Powder Coating) outside, not inside. If rain water or snow enters inside of tubes via holes, it will make the tubes rusted inside. Product will be damaged rapidly from the inside
