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. 310lb(140kg) per
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 Fig.17.0 pg.4.
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) / Max. Arrest force: 1800lb(8kN).
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. WARNING! Always
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 5,000lb(22.5kN) or 2 times the
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.

SAS Sample Length of Fall (LOF) Plans/Attic Fall Hazards
The sample plans shown in this manual are intended as a guideline to assist a
competent or qualified person in developing a job specific fall protection plan.
The LOF includes several factors that can be used to calculate ground clearance
between the work surface and a lower level or obstacle below. Three of the most
common attic space fall hazards are:
*Plunge Fall: Minor degree of angle and parallel from the SRL connection point
straight through open framing. No significant swing fall. See Figs. 9.0-9.1.
*Swing Fall: A fall that occurs when the tie-off point is directly overhead and
the worker has moved a short length perpendicular or parallel to the tie-off
point. See Figs. 11.0-12.0.
*Compound Swing Fall (CSF): A fall that occurs at an angle perpendicular
to the tie-off point above. See Figs. 11.0-12.0 shown on page 3.
*X Travel: The distance the SRL cable slides along the bottom chord toward
the tie-off point center of gravity. See Figs. 11.1-11.2.
*SAS definitions used for this manual.
Calculating the Length of Fall (LOF)
Sample plans “A” and “B” shown at Figs. 9.0-9.1 illustrate the length of a plunge fall
where there is a minimal amount of travel perpendicular or at an angle from the tie-off
point above. See Fig.9.4. Traveling more than 4-6ft away from the tie-off point above
may result in damage to the framing when the SRL cable comes in contact with a bottom
chord, adding to the LOF.
Sample Plan “A” Horizontal Lifeline System (HLLS)
Single HLL: Maximum 2 persons.
2 or More HLL in Series: 2 persons 1 leg or 1 person each leg. That means when HLL’s
are rigged in series, no more than 2 persons may be attached to a single leg at any time.
A horizontal line is required to be installed at a 30º angle or optional 5º angle when used
with metallic energy absorber No.1059-A. Using a 20ft HLL at a 30º will add 69” to the
distance between the WS-Truss Barr connector and the work surface. See Fig.9.0 and
Table 2.0. When a worker travels along the HLL, tension in the SRL cable will confine
the fall between the bottom chord spacing and will take up any line slack in the HLL. If
the entire system is in tension, the line slack will be reduced significantly. Sample Plan
“B”: The WS-TrussBar is used as a single anchor point, eliminating the HLL line slack and
reducing the LOF.

*Compound Swing Fall (CSF)
Open spaces between the framing at the work surface and angular or
perpendicular travel away from the tie-off point above as shown at Figs.
11.0-12.0 will result in a CSF, a combination of a plunge fall and swing fall.
Sample plan “C”: Shown at Fig.11.1, the worker has traveled at an angle
of about 7ft(84”) from the tie-off point above. Shown at Fig.12.0, the tie-off
point is 4-1/2ft(54”) above work surface. Deduct the SRL service length of 30”
(84”-54”=30”) added to the LOF. *SAS term used for illustration purposes.
Horizontal Lifeline Systems: There are two primary SAS HLL systems that
are compatible with the WS-TrussBar. Both require the use of SAS mfg. SRL’s
Sidewinder™ or TossR™ series.
1) Fixed length HLL No.1335 @ 30º angle max. 1 worker per/single leg. Table 2.0
2) Fixed length HLL No.1336 @ 5º angle max. 1 worker per/single leg. Table 3.0
HLLS No.1336 requires the use of SAS No.1065-AC coil energy absorber.

Using an SRL with the WS-Truss Bar
SRL’s are designed for use with an overhead tie-off
point as shown at Fig.12.0 and may be used at lower
tie-off points or near the work surface when a fall
protection plan has been engineered by a competent
or qualified person. Swing falls and compound swing
falls are the primary hazard when working in attic
spaces over unsheathed trusses. The SRL service
length, the amount of cable deployed and the angle
of the cable in relation to the tie-off point increase the
severity of a CSF while also increasing the LOF.
Most residential top floors have a ceiling height
of 8ft and many interior walls. These factors need to
be included in a job specific fall protection plan.

WARNING: PROMPT RESCUE!
A plan for immediate rescue is necessary to
avoid serious injury, excruciating pain or
death resulting from suspension trauma.
Ladders strategically stationed on the
floor below the work area can provide
an immediate means of rescue.
Use SAS S.T.E.P. 6060 suspension ladder
and provide training in its use
for each worker.
WARNING!
