Passive Fall Protection Safety Products

Perimeter Clamp System

Versatile Perimeter Fall Protection

Meets OSHA Requirement 1926.502(b)

Garlock Safety Systems perimeter clamp delivers OSHA-compliant fall prevention with two different attachment methods to suit the application. And both unique mounting methods give workers 100% unobstructed access to the roof.

When configured as a clamp, it can tightly grip parapet walls between 8” and 24”. The adjustable stanchion ensures the top rail and mid-rail are at the correct height regardless of the parapet wall height.

If no suitable parapet wall exists, the clamp can be converted in seconds to a screw-down attachment system. Eight lag bolts secure it to the edge of the roof and deliver rock-solid fall prevention.
