No need to shut these gates behind you—springs automatically do it for you.

Keep personnel safe when transferring material between areas with different floor heights.

Combine posts, panels, and doors to create a barrier around equipment.

Framed in aluminum T-slotted extrusions, these customizable machine guards provide multiple points of attachment for other components and structures.

Attach to upright rack shelving to block off aisles.

To make a complete unit, team one or more belt barriers with a wall receptacle or receiver post.

Replace cassettes in retractable belt barriers.

Instead of a post, use these rings to hang chain between metal surfaces.

Links split in half and snap back together. Use to connect two lengths of chain.

Create a temporary barrier around hazards such as open manholes.

You can fill these with water for added stability and drain when not in use for easy transport.

Control the flow of air and material through duct systems.

Often added to existing systems, these gates install without disassembling duct. Also known as half gates.

No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes.

Save energy and increase comfort by heating and cooling only the areas that need it.

Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain consistent airflow despite changing environmental conditions.

Mount gates on one side of a doorway and lock them on the other for security without sacrificing visibility and air circulation.

Roll these portable, wall-mounted gates wherever you need temporary access control.

Slide these gates over steel guard posts to control access to parking lots and dock doors.

Designed for use in refineries and other demanding environments, these durable valves have a forged steel body that can withstand at least twice the pressure of other threaded valves.

With a forged steel body and bolted construction, these durable valves can withstand nearly 10 times the pressure of other socket-weld gradual on/off valves.

Also known as vacuum isolation valves, these block flow so you can install and remove gauges from your system. They can also be used to add or vent gases in high-vacuum systems.

These valves have socket-weld connections for bonding to unthreaded male plastic pipe.
