If you want to consider the weight bearing capacity of the door closer, you will consider the larger door closer! The next selection is based on the following points
1. Tightness. The door closer is a product that attaches importance to the degree of sealing. Its work must be carried out under the condition of sealing; Therefore, good sealing is the first indicator for selection. Do not think of the door closer with oil leakage as useless. Only door closers made of good materials and technology can prevent oil leakage!

We have no way to make up for it but rely on our manufacturer to repair it. In order to protect our consumers' rights, it is better to write these into the purchase terms!

The door closer shall not be selected carelessly, and the fire is as fierce as a tiger. Safety precautions must be paid attention to
