      The Capital Safety 2100185 Counterweight Anchor is intended to provide an engineered anchor point for use in a fall protection system. This means that the design is specifically engineered to be appropriate for you (or an employee) to tie off using a lanyard or SRL. The mention to a 5,000 lb rated anchor point is in reference to a non-certified anchorage. This is a very common means of explaining the strength needed for a tie-off point when setting up your gear for fall protection. We use this all the time when speaking with customers. Somewhat different, a certified anchorage (designed by a qualified person) need only be rated to 2 times the maximum arresting force, in the event of a fall. Kind of a different animal. To help further explain, I have included the 2100185 Counterweight Anchor instruction manual, and a bulletin from Capital Safety related to certified anchorage points.

    We have multiple types of flat roofs on out facility.
    The one that gives me the most concern is a raised rib metal roof with multiple skylights in it.
    If I set up a minimum of 8 feet away, with the base bridging as many ribs as possible will this product still arrest a fall?

      The counter weight system is designed for flat roofs only and would not work for this application. The minimal friction of the ribs may cause the system to slide. Please call one of our product experts on 1800-829-9580 for specific application recommendations.

    Is this product only made for one person? is it possible for two people to tie off at the anchorage point?

      Only 1 person can be tied off to this system. It will not be able to support 2 or more people.

    Could I use 2 of these counterweight systems on a flat roof and install a cable between and use the cable to tie off to as long as our lanyard does not allow me to get any further than the edge of the roof. We have a flat membrane roof that is probably 135 feet by 100 feet. We also have tie off's that are attached to the roof on one end of the roof that are about 3-4 feet from the edge of the building. Could we attach a cable to these and to one off the counterweights and accomplish the same thing?

      The counter weight systems can't be used in that way. It's only designed to arrest the fall of 1 worker. The set up you described increases the forces on the anchor point exponentially. You'll need a horizontal life line system which typically can handle 2 workers. This system will require 2 anchor points both rated to 5000lbs.

    Is this anchor suitable for a window washer to use for rappelling down a building when they would have no other tie off point on the roof?

      This item is made as a personal fall arrest system, not a rappelling counter anchor unfortunately.
