A Frame Barricades

It's a portable traffic control device made up of two triangular leg panels and reflective striped boards, used to warn and direct traffic in work zones.

White plastic A-Frame legs, and a reflective striped barricade board that slides into the legs

The boards are 8 inches tall and available in 6-foot or 8-foot widths.

No, all parts are sold separately — legs and boards are purchased individually, allowing you to replace worn components without buying the entire barricade.

Depending on how many boards are used, this can be configured as a Type I (one board) or Type II (two boards)

It's made from impact-resistant high density polyethylene (HDPE)

Yes, it is NCHRP 350 approved when used with plastic rails and a barricade light.

The legs have built-in stacking lugs that allow them to nest together securely for slip-free storage and transport.

Assembling an A-Frame barricade is pretty straightforward. You stand two leg panels upright facing each other, spread apart at the base so they're stable. The legs have horizontal slots or channels built into them — you simply slide the barricade board(s) through those slots from one side until the board spans across both legs. The board rests in the slots by gravity, no tools or hardware needed. If you're building a Type II, you add a second board into the additional slots on the legs. Once the boards are in place, adjust the leg spread so the barricade stands firmly on its own. To break it down, you just slide the boards back out and fold or stack everything flat for transport.
