Blocker

The blocker icon represents a barrier or obstacle that prevents progress or access. It is typically depicted as a rectangle or square with a bold line or shape through it, indicating restriction or limitation. This symbol originates from general use in diagrams and flowcharts to represent a blockage or impediment.

In real-world applications, the blocker icon appears in software development tools like Jira, Trello, or Asana to indicate a task or issue that is blocking progress. It is also used in workflow management platforms like Notion or Figma to signify a hold or pause in the process.

From a UX perspective, the blocker icon communicates that there is an issue or impediment that needs to be addressed before progress can be made. It helps users understand that a task or process is being blocked and that action is required to resolve the issue.

Blocker is one of 14,082 icons in Arcticons, made by Donnnno and released under CC BY-SA 4.0. It is drawn on a 48 × 48 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds BlockerIcon to components/icons/arcticons-blocker.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed BlockerIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Blocker icon, or any of 14,082 Arcticons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 48 × 48 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Blocker", so screen readers say what it does.

Yes. BlockerIcon passes every SVG prop to the svg element, so <BlockerIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes, with conditions: CC BY-SA 4.0 asks you to credit the author (Donnnno), and icons you change must use the same license. The full terms are in the license, linked on this page.

Yes. CC BY-SA 4.0 asks you to credit Donnnno, and icons you change must be shared under the same license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are block, stop, limit, barrier, obstacle and restrict. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Blocker in another set.
