When purchasing the Nexakey NX-280B Bolt Lock, it is important to ensure that your door is compatible with the lock’s specifications. This lock is most suitable for heavy doors, supporting weights of up to 280 kg, so you should confirm the weight and size of your door before making a purchase. While installation is straightforward, consulting a professional can be helpful if you have any concerns. It is important to note that this lock is not suitable for lighter doors; therefore, if your door does not meet the weight requirement, it may not be the best fit. However, if you have a sturdy, heavy swing door, this lock will serve you well.
