Clarification on Anchor Type and Specifications

It is important to understand the specific design and the implications of the product’s specifications.

• Anchor Type: This is a hollow cavity anchor with a specific head style. Its function relies on having an empty space behind the wall or ceiling panel for the spring-loaded “toggle” wings to open and brace against the back surface.
• “Open Type” / Hook Head: The term “Open Type” refers to the fact that the anchor is fitted with an open hook screw instead of a standard bolt head or a closed eyelet. This design is ideal for directly hanging items that have a loop, chain, or wire, eliminating the need for an additional hook or connector.
• Conflicting Specifications (Size Range): The product page lists a very broad size range of M6-M20. This indicates the product serves two distinct markets:
  • Light to Medium Duty (e.g., M6, M8): These smaller sizes are perfect for residential and commercial applications in standard drywall or plasterboard. They are ideal for hanging plants, lightweight light fixtures, and decorations.
  • Heavy Duty (e.g., M10 up to M20): These are robust, industrial-grade anchors. They are not intended for standard drywall but are designed for use in more substantial hollow materials like hollow concrete block (CMU) or for suspending heavier items like signage, conduit, or light machinery from ceilings with a service cavity. This explains the “Heavy Industry” application listed on the page.

Product Mechanism and Installation

The anchor’s strength is derived from the large bearing surface created by the toggle wings behind the hollow material.

• Mechanism: The anchor consists of two main components: an open hook screw and a threaded, spring-loaded toggle wing assembly. The wings can be folded flat to pass through a drilled hole, after which they automatically spring open inside the cavity.
• Installation Process:
  1. Select the appropriate size toggle anchor for the intended load and wall/ceiling material.
  2. Drill a hole in the surface that is large enough for the folded toggle wings to pass through.
  3. Unscrew the toggle wings from the hook screw.
  4. Screw the toggle wings back onto the end of the hook screw by only a few turns.
  5. Fold the wings flat against the screw.
  6. Push the folded wings through the drilled hole until you feel them spring open within the wall/ceiling cavity.
  7. Pull back gently on the hook to seat the wings flat against the inside surface.
  8. While maintaining slight tension, tighten the hook screw by hand (or with pliers for the final turns) until it is snug against the outer surface. This will clamp the wall/ceiling material between the hook’s base and the toggle wings.

Key Features

• Integrated Hook: The open hook head allows for direct, quick, and easy hanging of items without extra hardware.
• Superior Hold in Hollow Materials: The toggle wings distribute the load over a large area behind the wall/ceiling, providing excellent pull-out resistance.
• Versatile Application: Suitable for a wide range of materials, including drywall, plasterboard, hollow block, and suspended ceilings.
• Easy Installation: The spring-loaded design and simple process make it accessible for both professionals and DIY projects.
• Corrosion Resistance: The White Zinc Plating provides good protection against rust in indoor environments.

Common Applications

Light to Medium Duty (e.g., M6-M8 in Drywall/Plasterboard):

• Suspending hanging plants from ceilings.
• Hanging decorative items, mobiles, or light-duty swag lamps.
• Securing chains for signs or displays.

Medium to Heavy Duty (e.g., M10-M20 in Hollow Block/Industrial Settings):

• Suspending lightweight ductwork or cable management trays.
• Hanging industrial lighting or signage from hollow concrete block ceilings.
• Creating suspension points for tools or equipment in workshops with hollow walls.
