Super Anchor Safety 2835 WS TrussBar™ Attic Anchor

The WS-TrussBar™ is an SAS exclusive design specified for use in attic spaces where other types of fall protection anchorage devices are not practical to install. Manufactured from lightweight aluminum, the WS-TrussBar™ easily installs to the underside of all standard size top chords and is adjustable for 12”, 16” and 24” top chord spacing. The bar legs easily rotate to compensate for imperfect top chord spacing. Use for single person PPE tie-off or HLL systems. This anchor can be used as a temporary device or can be left permanently for future use.

• 5,000lb min. tensile strength
• Lightweight aluminum 6.5lb
• Easily adjustable for standard top chord spacing
• Supplied with re-useable WS wood screws
• Single person tie off with lifelines or SRL’s
• Use with HLL systems no. 1335 and 1336 for a maximum spacing of 20ft.
• Can be used as a permanent tie-off point for attic access as required by confined space standards
• English/Spanish instruction manuals

• Device: temporary/reusable attic truss anchor for 1 person fall protection (indoor use on wood framing)
• Structure attachment: mounts across adjacent 2× framing members (typical 24 in on-center trusses/rafters) using WS wood screws
• Material: powder-coated mild-steel bar with stainless-steel connector hardware (ring/D-ring)
• Dimensions: fits 24 in on-center; bar length approximately 28–32 in; bar width about 3 in; connector ring ~2.0 in inside diameter
• Weight: approximately 6–8 lb per kit (bar plus WS screws)
• Strength rating: minimum tensile/breaking strength 5,000 lb
• User capacity: single user up to 310 lb including tools and equipment (when used with an energy absorber per instructions)
• Fasteners: WS wood screws (3–3.5 in typical) in specified pattern; do not mix fastener types
• Placement: install over sound structure and as high as practical relative to the work area; align with expected fall path to reduce swing-fall
• Service zones: fall arrest generally within ±30° of vertical to the anchor; fall restraint allowed where no free-fall hazard exists
• Finish: powder-coated for visibility and corrosion resistance
• Compliance: OSHA 1926.502; ANSI Z359.1 / A10.32 (when installed and used as directed)
• Inspection/retirement: inspect before each use and periodically by a competent person; remove from service after any fall event or if damage/deformation is observed

• Q: Where should I install the TrussBar Attic Anchor for safest use?
  A: Mount it across two adjacent attic framing members (trusses or rafters), directly over sound structure, and as high relative to the work position as practical. Keep your tie-off in line with the expected fall path to reduce swing-fall and avoid side- or back-loading.
• Q: What fasteners are acceptable, and can I mix different hardware?
  A: Use only the specified WS wood screws in the provided hole pattern. Do not mix fastener types, do not substitute sizes or grades, and ensure the screws achieve full embedment into the framing.
• Q: Is the TrussBar intended for permanent installation or structural bracing?
  A: No. It’s a temporary, reusable personal fall protection anchorage only. Remove it when the task is complete, and never use it for bracing, alignment, hoisting, or lifting.
• Q: What inspections are required, and when must the anchor be removed from service?
  A: Perform a pre-use check before each shift and periodic inspections by a competent person. Remove the anchor from service after any fall event or if you see deformation, corrosion, elongated holes, cracked welds, or damaged hardware.
