About the Prison Bars Lock black outline icon
Six vertical jail bars run between a thick top rail and a bottom rail, with a small lock plate and keyhole fixed to the leftmost bar. That keyhole turns a plain grille into an unmistakable locked cell door, standing for detention, arrest, confinement and blocked access. Use it in crime news sections, legal and court apps, prison reform infographics, game UI for captured states and account lockout screens.
The bars are evenly spaced and equal in weight, so the lock plate becomes the only focal detail and sits low on the left for balance. Pair it with handcuffs, gavel and police badge icons. The keyhole disappears under 24 px — use a plain bars variant for dense lists.
This is the black outline version of the prison bars lock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
