Its function relies on having an empty space behind the wall or ceiling panel for the spring-loaded &#8220;toggle&#8221; wings to open and brace against the back surface.<\/li>\n<li><strong>&#8220;Open Type&#8221; \/ Hook Head:<\/strong> The term &#8220;Open Type&#8221; refers to the fact that the anchor is fitted with an <strong>open hook screw<\/strong> 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.<\/li>\n<li><strong>Conflicting Specifications (Size Range):<\/strong> The product page lists a very broad size range of <strong>M6-M20<\/strong>. This indicates the product serves two distinct markets:\n<ul>\n<li><strong>Light to Medium Duty (e.g., M6, M8):<\/strong> 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.<\/li>\n<li><strong>Heavy Duty (e.g., M10 up to M20):<\/strong> These are robust, industrial-grade anchors. They are not intended for standard drywall but are designed for use in more substantial hollow materials like <strong>hollow concrete block (CMU)<\/strong> or for suspending heavier items like signage, conduit, or light machinery from ceilings with a service cavity. This explains the &#8220;Heavy Industry&#8221; application listed on the page.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h4><strong>Product Mechanism and Installation<\/strong><\/h4>\n<p>The anchor&#8217;s strength is derived from the large bearing surface created by the toggle wings behind the hollow material.<\/p>\n<ul>\n<li><strong>Mechanism:<\/strong> 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.<\/li>\n<li><strong>Installation Process:<\/strong>\n<ol>\n<li>Select the appropriate size toggle anchor for the intended load and wall\/ceiling material.<\/li>\n<li>Drill a hole in the surface that is large enough for the folded toggle wings to pass through.<\/li>\n<li>Unscrew the toggle wings from the hook screw.<\/li>\n<li>Screw the toggle wings back onto the end of the hook screw by only a few turns.<\/li>\n<li>Fold the wings flat against the screw.<\/li>\n<li>Push the folded wings through the drilled hole until you feel them spring open within the wall\/ceiling cavity.<\/li>\n<li>Pull back gently on the hook to seat the wings flat against the inside surface.<\/li>\n<li>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&#8217;s base and the toggle wings.<\/li>\n<\/ol>\n<\/li>\n<\/ul>\n<h4><strong>Product Parameters<\/strong><\/h4>\n<div class=\"MarkdownTable_tableContainer__2k5Kh\" tabindex=\"0\" role=\"region\">\n<table>\n<thead>\n<tr>\n<th>Parameter Item<\/th>\n<th>Specification Description<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Product Name<\/strong><\/td>\n<td>Spring Toggle Open Type Fixing-WZP<\/td>\n<\/tr>\n<tr>\n<td><strong>Brand Name<\/strong><\/td>\n<td>Duojia<\/td>\n<\/tr>\n<tr>\n<td><strong>Place of Origin<\/strong><\/td>\n<td>Hebei, China<\/td>\n<\/tr>\n<tr>\n<td><strong>Material<\/strong><\/td>\n<td>Carbon Steel<\/td>\n<\/tr>\n<tr>\n<td><strong>Surface Treatment<\/strong><\/td>\n<td>White Zinc Plated (WZP)<\/td>\n<\/tr>\n<tr>\n<td><strong>Available Sizes<\/strong><\/td>\n<td>M6-M20<\/td>\n<\/tr>\n<tr>\n<td><strong>Strength Grades<\/strong><\/td>\n<td>4.8, 8.8, 10.9, 12.9, etc.<\/td>\n<\/tr>\n<tr>\n<td><strong>Measurement System<\/strong><\/td>\n<td>Metric<\/td>\n<\/tr>\n<tr>\n<td><strong>Application<\/strong><\/td>\n<td>General Industry, Heavy Industry, Hollow Wall\/Ceiling Hanging<\/td>\n<\/tr>\n<tr>\n<td><strong>Certifications<\/strong><\/td>\n<td>ISO9001, ISO14001, ISO45001, SGS<\/td>\n<\/tr>\n<tr>\n<td><strong>Packaging Options<\/strong><\/td>\n<td>Small Pack + Carton + Pallet; Bag\/Box with Pallet<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h4><strong>Key Features<\/strong><\/h4>\n<ul>\n<li><strong>Integrated Hook:<\/strong> The open hook head allows for direct, quick, and easy hanging of items without extra hardware.<\/li>\n<li><strong>Superior Hold in Hollow Materials:<\/strong> The toggle wings distribute the load over a large area behind the wall\/ceiling, providing excellent pull-out resistance.<\/li>\n<li><strong>Versatile Application:<\/strong> Suitable for a wide range of materials, including drywall, plasterboard, hollow block, and suspended ceilings.<\/li>\n<li><strong>Easy Installation:<\/strong> The spring-loaded design and simple process make it accessible for both professionals and DIY projects.<\/li>\n<li><strong>Corrosion Resistance:<\/strong> The White Zinc Plating provides good protection against rust in indoor environments.<\/li>\n<\/ul>\n<h4><strong>Common Applications<\/strong><\/h4>\n<p><strong>Light to Medium Duty (e.g., M6-M8 in Drywall\/Plasterboard):<\/strong><\/p>\n<ul>\n<li>Suspending hanging plants from ceilings.<\/li>\n<li>Hanging decorative items, mobiles, or light-duty swag lamps.<\/li>\n<li>Securing chains for signs or displays.<\/li>\n<\/ul>\n<p><strong>Medium to Heavy Duty (e.g., M10-M20 in Hollow Block\/Industrial Settings):<\/strong><\/p>\n<ul>\n<li>Suspending lightweight ductwork or cable management trays.<\/li>\n<li>Hanging industrial lighting or signage from hollow concrete block ceilings.<\/li>\n<li>Creating suspension points for tools or equipment in workshops with hollow walls.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>The Duojia &#8220;Spring Toggle Open Type Fixing&#8221; is a specialized anchor designed for hanging items from hollow walls and ceilings such as plasterboard (drywall), hollow-core doors, and hollow block.
