The Super Anchor Safety (SAS) ARS-Series Stainless Steel Anchor is a versatile fall protection anchorage device designed for both permanent and temporary use. It is compatible with all flashing systems supplied by SAS and is engineered to attach over wood truss top chords, rafters, and I-Joists using a single grade 8 bolt.
The primary function of the SAS anchor is to provide fall arrest or fall restraint for one person, supporting a maximum body weight of 340 lbs (154 kg) including tools and equipment. For horizontal lines or multiple users, only ARS 2x8/2x12-11 ga. anchors should be used, workers must not be exposed to a free fall, and the system must be designed by a "Qualified Person."
The anchor is available in various configurations to suit different applications:
Installation: Anchors are supplied with SAS-certified grade 8 x 5/16" attachment bolts of sufficient length to allow a lock nut to be installed. Six 1-1/4" teko nails are used to stabilize the anchor position and prevent movement during use.
Drill Through Method: 2x4/2x8/2x12/I-Joist and Wall anchors can be installed by drilling through the top chord or rafter using a 5/16" (9mm) drill. Users must not modify the anchor by drilling additional bolt holes or enlarging factory bolt or teko nail holes.
Blocking 2x4 Top Chords: When 2x8 anchors are installed over 2x4 top chords or rafters, a 24" length of 2x4 blocking is required. This blocking must be attached to the underside of the top chord to prevent movement. This setup provides greater resistance to force loads than a 2x4 anchor.
Framing Requirements: Anchors must be installed onto top chords that are 2x4 or greater in dimension. The framing must be capable of supporting a 5,000 lb (2,260 kg) load or two times the intended fall protection load. Installation is prohibited on damaged or spliced top chords.
Sheathing: Sheathing over top chords must be a minimum of 7/16" OSB or plywood and installed over the anchor shoulders to allow the attachment bolt to be installed under the top chord. If sheathing is already in place or if anchors are to be evacuated after use, a 3"x 3" opening must be cut through the sheathing centered over the top chord.
Connectors: Connecting hardware must comply with current standards. Attachment should only be through the "Connector Attachment Hole." Users must prevent lifelines/lanyards from intersecting anchor stems to avoid cutting or severing hazards. Snap-hooks and carabiners must comply with industrial safety standards. Auto-lock type carabiners require two separate movements to open the locking barrel.
Personal Protection Equipment (PPE): PPE, including harness, lanyard, lifeline, shock absorber, and rope grab, is essential for fall protection. A shock or energy absorbing device is required whenever there is exposure to a free fall when using SAS anchorage devices. SAS anchorage devices are factory-ensured for compatibility with PPE manufactured by SAS. Users must ensure component compatibility when using equipment supplied by other manufacturers.
Rigging Lifeline for Free Fall: The SAS method for adjusting PPE to limit free fall length involves positioning the worker directly below the anchorage point above and at the leading edge. The lifeline is pulled tight, and all slack is removed from the energy absorber and rope grab. The rope grab is then adjusted to allow for the additional free fall.
Anchor Service Zones: Circular Service Zones are plotted using a compass between the ridge and Free Fall Line. A worker standing at the leading edge is allowed to free fall 72" (1.8m) before the PPE begins to arrest the fall. The D-Ring is 52" above the leading edge, allowing an additional 20" of length in the lifeline, lanyard, or SRL. The Free Fall Line used for plotting service zones is located 20" from the leading edge.
Adjustment Zones: Leading edges at roof gables create a swing fall hazard. Slack in the lifeline must be adjusted as the worker moves up-slope to limit the free fall to 6 ft.
Zone Margins: Areas outside the Service Zone (SZ) radius line, such as hip corners, may require additional anchors.
Visual Inspection: Anchors and the supporting structure must be inspected before each use.
Underside Inspection: The attachment bolt and lock nut must be installed as shown for each anchor type. For ARS series, three teko nails must be installed through each anchor leg. If the anchor has shifted position, an inspection is required to determine the cause. Anchors subjected to a free fall or other force must be removed from service.
Topside Inspection: The anchor stem and connector hole must be inspected. If there is evidence of damage or if the anchor has been subjected to a fall impact, it must be removed from service.
Detent Locking Pin Function Test (for Moveable/Temporary Anchor): Before each use, a detent pin function test must be performed. In the locked position, the handle should not pull out. The anchor must be removed from service if the test fails, if the handle is damaged, if the pin shaft is bent, or if one or both ball locks are missing. The pin must be inspected to ensure both ball locks are intact. The detent pin must be in the locked position through both anchor leg attachment holes.
Modification/Non-Specified Use/Replacement: Anchors must not be re-formed, cut, bent, welded, drilled, modified, or repaired. They must not be used to secure scaffolding, guy lines, warning lines, materials, hoisting, or tethering for large animals.
Removal From Service: Anchors subjected to non-specified use, damage, alteration, or in-service loading (free fall) must be removed from service.
Inspection: An inspection must ensure that the anchor point framing subjected to a free fall or other force load has not been damaged.
