2. How can i buy product with cheaper prices?


As seller, we understand that customers always want to buy product(s) at low price. Lower prices mean more customers. Therefore, our most difficult job is pricing, which is both able to offer reasonable prices that customers can afford while being able to compete with other competitors, and can cover all the costs to make a profit. Like all other companies, we have to wonder, think and discuss a lot before making a suitable price policy in each stage of operation of the company. 

As you know, we are a manufacturing company in Vietnam (a small country located in Southeast Asia). To export products to the US and other countries - especially heavy products - we have to bear many high costs, especially shipping costs, customs fees, storage costs and marketing costs. We can't even lower the prices, because if they don't cover costs, we will lose money, and our company will stop running. In order to serve customers in long term with a high responsibility and good quality, our prices must be as current. Hope you understand and don't expect our prices will be much lower than products value and the value of our effort to bring that value to you.

However, you can buy products at a lower price, using the following methods:

+ Buy together: Ask friends to buy products with you. If you buy more than 2 units we will reduce the total amount for you. Contact us for detail information.

+ Repurchase again: You can buy our products again in the future for yourself or for your friends or relatives. You will definitely get a discount. Contact us and provide us with your previous Order ID

+ Buy returned products: Please contact us when you want to buy returned items because the quantity is limited.

3. What are the similarities and differences between KT One-tiered folding stand frame (Model KT1.1518, model KT1.1520, model KT1.1520YG and KT1.0914) and KT Double-tiered folding stand frame (Model KT1.HT)?

Answer: a) The similarities: 

They all have 08 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 adjustable KT folding pull up bar free standing

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:


+ Secondly, KT One-tiered folding stand frame can be folded in 8-10 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 distance-setting-bars but also the rack bars (which support the lower handle-bar) to fold the KT double-tiered stand frame

4. What are the similarities and differences between 2 models of KT One-tiered folding stand frame: Model KT1.1518 and model KT1.1520?

Answer: Model KT1.1520 and model KT1.1518 are identical in structure. The differences between them are max load capacity and max height, so model KT1.1520 is made from bigger and thicker iron tubes:

+ Gross weight of model KT1.1518 is 37.4 pounds (17kgs), but gross weight of model KT1.1520 is 63.9 pounds (29kgs).

+ Max load capacity of model KT1.1518 is 440.9 pounds (200kgs). Max load capacity of model KT1.1520 is 771.6 pounds (350kgs). The limitation 440.9 pounds (200kgs) means that at a specific time (short-term), Model KT1.1518 can withstand a max weight of 440.9 pounds (200kgs) combine with swinging and shaking movement of users without being bent, broken or collapsed. But in the long term, if users who have weight over 220.46 (100kgs) always train with model KT1.1518 will make the handle-bar bent

+ Max height of model KT1.1518 is 92.5 inches (235cm). Max height of model KT1.1520 is 100.4 inches (255cm)

Model KT1.1518 is suitable for users who are under 6 ft (183cm) tall and 200.4 pounds (100kgs) weight. If you are taller than 6 ft or weighty over 200.4 pounds, you should use model KT1.1520

7. Can I perform acrobatics or flying trapeze with KT folding stand frame?

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

8. Can i place your product(s) outdoor?

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, 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
