Window type gecko expansion anchors, also known as hollow wall anchors, are named for their ability to "cling" to the wall like a gecko. They typically consist of a spring steel clip that expands within the wall cavity to provide a secure grip, and a screw that threads into the clip to draw it tight against the wall.

Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.

Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.

Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required.

Advantage:

Window Installation: These anchors are ideal for mounting window frames in hollow wall constructions where traditional fasteners may not provide enough support.

Shelf and Rack Mounting: They are commonly used to attach shelves, racks, and other storage solutions to drywall or plasterboard walls.

Home Decor: For hanging pictures, mirrors, and other decorative items without the need for wall studs.

Office Furniture: Securely fasten desks, bookcases, and other office equipment to walls.

Scope of Application

Easy Installation: They can be installed quickly and easily with simple tools, often just a screwdriver or a drill.

High Holding Strength: Despite their small size, these anchors can support significant weight due to the expanding mechanism that grips the backside of the wall material.

Versatility: They are suitable for a variety of wall materials, including drywall, plaster, and brick veneer.

Invisible Design: Once installed, the anchor is hidden within the wall cavity, providing a clean, finished look.
