Membrane Roofs

Kee Line provides one of the only upright posts that can be weathered with a standard pipe detail.

Metal Sheet Roofs

Utilizing the same range of brackets as standard roof systems, Kee Line can be installed quickly and easily on standing seam roofs.

Structrual Roofs

Kee Line structural posts can be used to tie back directly to the frame of the building. These well-built, heavy-duty anchors can be welded to,, wrapped around, or clamped onto underlying beam structures. They can also be mounted directly to concrete.


Provides personal protection for up to two users. Lifeline system is mounted directly above the user for tasks including overhead crane access, vehicle loading, machine & building maintenance, cleaning and access.


Kee Line for structures provides the horizontal lifeline components to allow mounting directly to concrete, steel, brick or stonework either in the horizontal or overhead application.
