Specified Use

WS-TrussBar is designed for use as a PPE anchorage point that attaches
to the underside of wood top chords in attic spaces as shown on pages
2-3 and Fig.13.0 pg.4.
User Specifications: 1 person max user wt.
single HLL leg including tools. May be used with lifelines, lanyards,
SRL's and horizontal lifeline system (HLLS).
HLL Leg: 2 end anchors with a single cable between them.
User PPE: Attach connecting components to the dorsal D-ring of a full
body harness as shown on pages 2-3 and
DO NOT use side or front D-rings or body belts. The use of a personal
energy absorber with a PPE lifeline or an SRL equipped with an internal or
external energy absorber are required for use with the WS-TrussBar.
Free Fall Max length: 6ft(1.8m)
Energy Absorber must be specified for the user's weight.

Non-Specified Use

DO NOT use for window washing or work positioning.
DO NOT install onto truss bottom chords unless supported by an interior
wall or other framing.

Fastener Specifications

Must be attached to framing with SAS supplied min. 2.0" or 2.5" length
WS hex head reusable wood screws only as shown at Fig.5.0.
WARNING! DO NOT substitute with other types of fasteners unless they have
been engineered by a qualified person or supplied by SAS. Use the lowest
torque setting to flush mount screws with the leg surface.
use eye protection when installing fasteners. DO NOT install screws by
hammering. DO NOT pry against the bar legs to remove fasteners.

Installation onto Top Chords

Framing must be capable of supporting
intended fall protection load. Install to the underside of 2x4 or larger
dimension top chord with sheathing that is structurally sound and free of
defects or damage. Attach 5ea WS 2.0" screws to each leg as shown at
Fig.3.0. Install the WS Bar on the underside of a 2x4 or larger dimension
top chord approximately 6-8" from a truss mid span web or king post
as shown at Fig.8.0. Clamp 1 leg to assist in stabilizing the bar during
installation if necessary.
Framing Options: King Post cross framing of at least 3 trusses may be
used when engineered by a competent or qualified person.
WARNING! DO NOT install where top chords are butt jointed. See Fig.16.2.
May be installed onto interior or exterior wall studs when sheathing is in
place.

Adjusting for Top Chord Spacing

The WS-TrussBar is adjustable for installation onto 12",16" and 24" o.c.
top chords(TC). Bar legs rotate to adjust for imperfect spacing between
TC's. The maximum width for leg spacing is 13", 17" and 25".
See Figs. 6.0-7.0 as an example for 24" TC's.
Leg Attachment Bolt Pressure Adjustment: To limit unwanted leg
movement, increase the attachment bolt pressure against the friction
washers as shown at Figs. 1.0-2.0. DO NOT allow bar legs to move freely.
Adjust pressure to allow some movement for installation. Friction washers
may require replacement due to wear.

Leg Bolts and Friction Washers

Use only SAS supplied replacement bolts, lock nuts and friction washers.
DO NOT substitute with other types.
