Safety Gates
No need to shut these gates behind you—springs automatically do it for you. Gates can be mounted to swing open to the left or right.
Gates that comply with OSHA 29 CFR 1910.28 meet standards for protection from falls and falling objects around walking-working surfaces. Gates that meet OSHA 29 CFR 1910.29 fulfill requirements for guardrail systems.
Style A gates close softly for safety. You can also adjust their tension to change how quickly they close.
Style B gates have a low profile.
Style C gates adjust to fit a wide range of openings.
Stainless steel gates provide excellent corrosion resistance.

Blast gates stop airflow when closed.
Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
304 stainless steel is more corrosion resistant than steel and aluminum.
