The terms "turn in" and "turn out" are not commonly used in the context of kitchen cabinet drawer handles. However, I can try to infer the possible meanings based on your description.
Inward-Turning Handles: These are drawer handles that, when installed, face the inside of the drawer or cabinet. They are designed to be discreet and offer a cleaner, more streamlined appearance. Inward-turning handles are typically installed on the top edge of the drawer or cabinet, and when closed, they are not immediately visible from the front. This style is often used in modern and minimalist kitchen designs.
Outward-Turning Handles: These are drawer handles that, when installed, face outward, towards the user. They are more prominent and provide a more traditional or classic look to the kitchen. Outward-turning handles are typically mounted on the front surface of the drawer or cabinet and are readily accessible for pulling or pushing the drawer open or closed.
It's worth noting that the terms "turn in" and "turn out" are not standard industry terms, so the meaning could vary depending on the context or the manufacturer's description. If you are considering different styles of cabinet drawer handles, it's a good idea to look at images or samples to understand the design and functionality better before making a decision. Ultimately, the choice between inward-turning and outward-turning handles comes down to personal preference and the overall aesthetic you want to achieve in your kitchen.
