The Guardian Fall Protection “CB-18 Roof Anchor” is the tried and true permanent fall protection anchor! This product is great for use with retractable lifelines, vertical lifelines, rope grab units, or horizontal lifeline systems and can be installed on concrete, metal or plywood substrates. The anchor’s 18 inch tall post extends past roofing substrate to keep attachment point high enough that it is sill accessible after the roof is complete. This round post also works well with most off-the-shelf flashing kits.

FEATURES:

• For use on wood or metal
• Durable galvanized finish
• Great for use with retractable lifelines, vertical lifelines, rope grab units, or horizontal lifeline systems
• Post extends past roofing substrate to attachment point accessible
• Round post works with most off-the-shelf flashing kits

Q. What if I don’t meet the decking/substrate requirements of a ¾” CDX plywood or 20 ga. metal?

A. There are a variety of different methods. You can use 2×4 bracing
for wood applications or you can lay a 4×4 sheet of wood or decking
down over the top of the area where anchor points are going to be
installed.

Q. Why?

A. Anything less than the above substrates will not hold 5,000 lbs.
which is the requirement for attachment areas. By using 2×4 bracing or
another sheet of material, screwed securely into the framing members
(truss or purlins), you are, in essence, making that section of decking
capable of meeting the 5,000 lb. requirement.

Q. What is the proper spacing if I want to run the 4 worker horizontal line system?

A. CB: 12’s thru 18’s: 20ft. on center SKYHOOKS: 16ft. on center

Q. How many workers does the horizontal cable system hold?

A. 4 in. FALL RESTRAINT per continuous run of cable; 1 in FALL ARREST per continuous run of cable

Q. How do I attach the cable system to the anchors? Do I attach to each one?

A. Terminate the cable on one end by running approx. 2 feet through the
anchor and clamping it back to the remaining cable with at least 3
cable clamps. For Skyhooks, run the cable through the large hole, then
through the small hole, and back through the large hole. * Run the end
of the cable line through each intermediate anchor (for Skyhook, run
only through the large diameter hole) * Do not stretch the cable tight!
Allow 6 to 8″ extra line per 20ft. to allow for slack * When selling
the line, also add the 2 feet and the slack * The slack absorbs some of
the impact in a fall

Q. Can I install a CB-1-B on a flat roof?

A. No. Because it is a flat anchor with no upright it cannot be
installed in any waterproof manner. It is intended for vertical
structures.

Q. Can I install a CB-1-W for a permanent application?

A. ONLY if it is installed as recommended and then given some sort of
weatherproofing finish. The current unit does not have any weather
protection and will rust when exposed.
