A perforated floor drain strainer is a device that is placed over a floor drain to catch debris and prevent clogs. There are many different designs of drain-lock, but they all share some common features. Here are some tips on how to design your own drain-lock:
The first step is to choose the material that you want to use. There are many different options available, but the most common materials are plastic and metal. Plastic is often cheaper, but it can be less durable than metal. Metal is more expensive, but it will last longer and is more resistant to clogs.
Next, you need to decide on the size of the drain-lock. This will depend on the size of the floor drain that you are using. You need to make sure that the lock is large enough to fit over the drain and catch all of the debris.
