A PVC Fisher Wall Plug, also known simply as a wall plug or rawl plug, is a type of anchor used in wall or ceiling installations to allow a screw to be securely fastened into soft materials like drywall, plaster, or masonry. These plugs are essential in preventing screws from loosening or pulling out over time, especially in hollow or fragile wall structures.

The plug is typically made from PVC (polyvinyl chloride), a flexible yet durable plastic that provides strength, resistance to wear, and good load-bearing capabilities. The design of the PVC Fisher wall plug consists of a cylindrical shape with internal grooves or ribs that help the plug grip the screw firmly when it is inserted. As the screw is driven into the plug, the plug expands inside the hole, creating a tight hold within the wall. This expansion ensures that the screw remains secure even in materials that are too soft to hold the screw on their own.

Wall plugs are used in a variety of applications, including mounting shelves, securing picture frames, attaching electrical outlets, and installing other fixtures onto walls. They are commonly used in materials like drywall, plaster, brick, concrete, and masonry. The PVC material provides sufficient flexibility, allowing the plug to expand and hold well in different types of wall substrates. They can also be used in damp environments because PVC is resistant to corrosion and moisture, making them suitable for use in areas like bathrooms and kitchens.

The advantages of PVC Fisher wall plugs include their ease of use, secure grip, and reliability. They are easy to install, requiring only a drill to make a hole of the appropriate size for the plug, followed by the insertion of the screw. Additionally, these plugs can be used with a wide range of screw types, making them versatile for various fastening needs. They also help to distribute the load of the screw more evenly across the surface, preventing damage to the wall.

In summary, PVC Fisher wall plugs are a reliable and practical solution for anchoring screws into softer materials. Their design and durable construction provide a secure, long-lasting fastening solution, making them an essential component for mounting fixtures, appliances, and other items onto walls without causing damage or instability.
