Can the custom security door be rejected if it does not meet the size?

It depends on how your purchase contract is signed. If it is stated in the contract that they are responsible for the relevant dimensions, your purchase can be rejected if it does not meet the contract. If you send your time limit by mistake, they want double indemnity deposit. If the contract does not specify who is responsible, it depends on whether the size in the contract is customized according to their quantity. If it is customized according to their quantity, it should be their responsibility. But style is usually the responsibility of the customer. If they pay the deposit, they should make corresponding compensation according to the amount of the deposit.

Don't be afraid when customers encounter problems. Call the Consumers Association and sue them first, and then talk about it. Most merchants nowadays bully the weak and fear the hard, unless they don't want to do business. I really can't mess with him. I usually go to the Golden Week in March 15 and May 1. As long as you are right, you are not afraid of him. Evil will not suppress justice.
