1 Product Installation & Maintenance Procedures for: Commercial Roof Anchors (CRA) & Accessories #1032, #1033 #1032p, #1033p #1032a, #1033a # #1058 accessory parts

2 Our Commercial Roof Anchor is designed for low-slope and flat roof applications It has a 16x16 base plate with a 3 tubular riser in 12 or 18 heights Manufactured from high strength steel and hot-dipped galvanized or powder- coating finish Universal design attaches to wood, steel, or concrete decking It can be used as a single user anchor or in a system for a horizontal lifeline application for up to 4 users A special pass-through top has been designed for use as intermediate anchors in between end anchors

3 To become a Certified Installer the user must be able to read and understand the complete Instruction & Specification Manual for the Commercial Roof Anchor and/or the Horizontal Line System. The Certified Installer must also sign our Sign-Off Sheet stating that you have read and understood our Instruction & Specification Manual. Manuals are shipped with each and every anchor Manuals are available for download at Manuals are available in English, Spanish, and French Super Anchor is available for phone conference calls to answer any Technical assistance is also available via at

4 Strength Rating:5,000 pounds Max Strength:10,000 pounds Base Material:3/8 galvanized steel Riser Material3 thick wall tubing Fasteners:2 ½ #14 hex head Capacity:310 pounds Compliance:OSHA 1926:502 Base Flashing:30# lead Flashing base:ABS Plastic Flashing cap:ABS Plastic

5 This overview is taken from Single & Multiple User Specifications/Fall Arrest found on page 1 of the Instruction/Specification Manual 08 The CRA is rated for a single person with a maximum weight of 310 pounds including tools and equipment and is rated for Fall Arrest. The maximum length of one system is 120 end-to-end. The CRA is rated for up to 4 users when used in Fall Restraint or Work Positioning. A maximum of 4 workers can tie-off to the horizontal line system on the CRA as long as they are rigged in such as way as to not subject themselves to a free fall over the leading edge. The structure that the anchor is attached to must be capable of withstanding twice the intended fall protection load, or 5,000 pounds as per OSHA 1926 Example: The Maximum Arresting Force for a shock absorbing lanyard or retractable lifeline found in all personal fall arrest systems is generally 900 pounds or less. 900 pounds is the intended load for the anchor, and twice that is 1,800 pounds. 1,800 pounds would be the minimum strength requirement for the anchor attachment The CRA with the supplied fasteners is rated at 5,400 pounds when attached to a wood deck or a steel deck (see fig. 4 & 7 on page of the Instruction Manual). Minimum thicknesses apply

6 This overview is taken from Wood Framing with Plywood Sheathing & Anchor Fastening Specifications found on page 1 of the Instruction/Specification Manual 08 Installation of the CRA is very straight forward. The anchor must be installed in the center of a plywood sheet that is at least 4x4. The specification calls out for attaching to ¾ plywood. If the plywood is ½, then another piece of ½ plywood backer board must be installed either on the top or bottom of the primary piece of sheeting. The Primary piece of decking must be secured through a minimum of 3 top-chords and fastened on the perimeter edges 8 on-center with at least 21 ea. 2 x #14 deck screws. Attach the anchor using the factory supplied (40 ea. 2 ½ x #14) hex head screws. The fasteners must penetrate the backer board if one is to be used. Always do a visual inspection from underneath the structure to make sure proper penetration was achieved. Please reference fig. #4, 5, and 6 on page 1 of the Instruction/Specification Manual Use only factory supplied hardware unless otherwise noted in the Instruction/Specification Manual

8 This overview is taken from Steel Decking – 20 Gauge Minimum/Wood Sheathing/Rigid Insulation found on page 2 of the Instruction/Specification Manual 08 The CRA can be installed onto metal decking surfaces that are 20 gauge or thicker with the factory supplied fasteners by simply centering the anchor base plate fastener holes over the raised channel of the steel decking and attaching using the factory supplied 2 ½ #14 fasteners. Here are some notes if the decking is 20 gauge or less: Attach a second layer of metal decking that is 3x3 with #14 deck screws 8 on center through all raised channels of the metal decking. A 3x3 piece of pressure treated plywood backer board attached to the underside of the steel decking that is secured with grade 8 bolts can also be used. A 3x3 piece of plywood decking placed on top of the metal decking and position the anchor over the wood sheeting so that the hex head screws penetrate the raised channel of the metal deck. Secure with 36 of our factory supplied hex head fasteners If rigid insulation is being used, then the anchor needs to be bolted to the structure using the following method: bolt the anchor base to a ¾ x 24 square pressure treated plywood backer board on the underside of the primary sheathing. Drill through the insulation board, primary sheathing and backer board. Use 8 ea. ½ grade 8 bolts of sufficient length and secure with lock nuts and washers. Position the bolt holes over the raised channels if possible.

10 This overview is taken from Concrete Slab/Rigid Insulation found on page 2 of the Instruction/Specification Manual 08 The CRA has provisions so that it can be attached to a concrete slab. The concrete must be a minimum of 4 thick and rated at 2,000 p.s.i. There are 8 ea. 9/16 holes in the base of the CRA – these are the mounting holes for the concrete impediment bolts. Use a ½ impediment bolt that extends down at least 3. Note that the bolts must maintain a margin of ½ from the bottom of the concrete slab. The concrete must be cured sufficiently to withstand the intended fall protection load before using for fall protection. Review for concrete decks: All 8 mounting holes must be utilized Use only ½ impediment bolts (wedge anchors) that have a rating of 6,000 pounds or higher The concrete must be a minimum of 4 thick It must have a minimum p.s.i. rating of 2,000

12 This overview is taken from Steel I-Beams/Wood Beams found on page 2 of the CRA Instruction/Specification Manual 08 The CRA may be attached onto a steel or wood beam using a backer plate that mirrors the mounting plate. The anchor attached to the beam by using all-thread or grade-8 bolts. The backing plate is 3/8 thick steel and has 9/16 holes. The all-thread or grade 8 bolts need to be ½ x Notes regarding Attaching to Steel/Wood Beams: Minimum grade 5 all-thread must be used Minimum grade 8 bolts must be used Backing plates can be purchased through Super Anchor Safety Engineered Drawings are also available by contacting Super Anchor Safety

13 Recommended Spacing between anchor locations is as follows: No more that 20 apart from each other and 6 – 10 from the leading edge:

14 This overview is taken from Super Anchor Safety Instruction Manual Addendum 2010 – Horizontal Line System (HLS) The Commercial Roof Anchor has the ability to be used as a mounting system for a horizontal lifeline. There are 2 ways that this can be done: #1 – End Style anchors can be placed every 20 and a cable can be run through the top of the anchor point. The user must disconnect his system and reattach to the next run of 20 of cable. #2 – Pass Through style anchors allow the user to pass-through the anchor and thus stay connected to the system 100% of the time. A special top is manufactured onto the CRA and allows a O ring to pass through the cable guide. The remainder of this presentation will address the following: Description of the Pass Through Top (PTT) Specifications of Use Attaching the cable to the Anchor The use of Shock or Energy Absorbers Warnings to users Detailed Pictures of the System

15 This overview is taken from Super Anchor Safety Instruction Manual Addendum 2010 – Horizontal Line System (HLS) Description of PTT Anchor Description of the PTT Anchor: The Pass Through Top Anchors are fitted with a special ½ cable guide at the top of the anchor. The cable is strung through the PTT and allows an special O Ring to pass through the cable guide with a lifeline or lanyard attached. The feature allows one or more workers to travel the length of the horizontal line without having to disconnect their PPE, lifeline, lanyard, or shock/energy absorber.

16 This overview is taken from Super Anchor Safety Instruction Manual Addendum 2010 – Horizontal Line System (HLS) Specification of Use: When building a Horizontal Lifeline System using the CRAs and CRA-PTTs, part #1032 or #1033 must be used as the primary end point anchors. Use the PTT anchors as the intermediate anchor points that go in between the end anchors. The maximum length of each horizontal line is not to exceed 120 and spaced no more that 20ft apart. Do not use the PTT anchors for horizontal line ends or corners. PTT anchors may be used for one person to connect his PPE provided the connectors are compatible and prevent disengagement. NOTE: Custom CRA & CRA-PTT risers can be fabricated for pitched roofs.

17 This overview is taken from Super Anchor Safety Instruction Manual Addendum 2010 – Horizontal Line System (HLS) Cable Attachment: Prior to rigging the cable ends, install up to 4 O rings onto the cable. There are 2 ways to do this – with or without turnbuckles: End Loops without Turnbuckles: Add 36 to the length between end/corner anchor points (see fig. 22a and 22c) Feed 18 of cable through the riser top connecting ring and attach cable clamps as shown in (fig. 20). Tighten clamp nuts to 45 lbs. Repeat for the opposite end. End Loops with Turnbuckles: Use the same formula as above and deduct 29 of cable length for each turnbuckle that is used. Adjust the turnbuckle threads out to allow a minimum of 2 of thread buffer to remain. Connect one end of the turnbuckle to the end/corner anchor point (see fig. 22a) and secure the shackle pin and cotter pin. Repeat the procedure for the opposite end. For systems longer that 60 total we recommend using 2 turnbuckles. Cable Slack: Always maintain a minimum of 2 of slack between end/corner anchors. A failure to do so may result in damage to the anchor fasteners or the supporting structure.

19 This overview is taken from Super Anchor Safety Instruction Manual Addendum 2010 – Horizontal Line System (HLS) Energy Absorbers: Personal Protective Equipment energy absorbers are required for each person connected to the HLS and must be attached to the O ring as shown in fig. 16c. Do not use webbing type energy absorbers to attach a cable to an anchor. A metallic energy absorber (#1059) may be used as a component of the horizontal lifeline system as shown in fig. 17 and 23. Attach the absorber to one or both CRA end/corner anchors. Do not attach absorbers to a PTT anchor. Turnbuckles may be connected before or after the absorber. Do not use HLS if any of the following conditions are observed: Energy Absorber is deployed Cable is cut or frayed Absorber/Turnbuckle pins or cotter pins are missing Crosby clamps are missing Turnbuckle has less than 2 of thread buffer Horizontal system has been subjected to a free fall or other force Anchors are pulled away from attachment point Cable ends are attached to a PTT anchor
