UNIVERSAL MODULAR PLATFORM SYSTEM
WARNING! READ CAREFULLY AND UNDERSTAND ALL INSTRUCTIONS BEFORE STARTING INSTALLATION. FAILURE TO
FOLLOW ALL INSTRUCTIONS MAY RESULT IN DEATH OR SERIOUS PERSONAL INJURY.
IMPORTANT
• Equipment should not be altered or modified from its original design without consultation with the manufacturer.
• Equipment which is damaged or becomes damaged during use, handling, or shipping should be set aside and not used.
• WARNING! Failure to anchor unit properly with the correct layout dimensions can result in product damage not covered under
warranty – product is not designed to be self supported without anchor bolts. Failure to secure all fasteners may result in death or
serious personal injury.
• Do not assemble unit off of anchor bolts and then lift onto them. System should only be assembled in its final location. Never move
an assembled system.
• WARNING! Backing plates must be used where designated in the instruction manual. Failure to use backing plates where
designated may cause equipment to fail and may result in death or serious personal injury.
• TORQUE DATA:
All ½” bolted connections = 678 in-lbs. (56 ft-lbs.) lubricated or 904 in-lbs. (75 ft-lbs.) dry +/-10%.
For 5/8” anchor bolts = 900 in-lbs. (75 ft-lbs.) lubricated or 1080 in-lbs. (90 ft-lbs.) dry +/-10%.
Use of impact wrenches NOT sanctioned.
• WARNING! After a usage period of 60-90 days, check all fasteners to ensure connections are secure. Periodic inspection is
recommended to insure all fasteners are secured. Failure to secure all fasteners may result in death or serious personal injury.

ASSEMBLY CRITERIA
Verify proper installation according to ErectAStep installation manual. In addition, make sure to check the following specifically.
• Ensure all anchor bolts are installed properly at the stair base and tower.
• Ensure leading edge of platform and stair gusset are flush.
• Ensure tower is vertically plumb.
• Ensure all bolts are properly tightened according to ErectAStep installation manual.
– No impact wrenches are to be used – tighten all bolts by hand.
• Ensure that stair guardrail posts are vertically plumb.

UNIVERSAL MODULAR PLATFORM SYSTEM
INTRODUCTION:
ErectAStep modular platform and stair systems are
pre-engineered and designed for unlimited
configurations. This universal design allows for
optimum flexibility to gain access and egress over
and/or around obstructions, equipment, walls, etc.
ErectAStep uses only the highest quality material in
the construction of its modular system to ensure the
quality, strength, and dependability for years. It is
very important to follow configuration guidelines
and installation instructions for your ErectAStep
system. Design limitations can exist with respect to
required supports, adequate footings, and
prescribed application.

SYSTEM ANCHOR LAYOUT
PLAN VIEW
PAD LAYOUT
ANCHOR BOLT POSITION
• Anchor bolt positions should be laid out by
mathematically calculating positions of anchors. (see
component anchor layout or ErectAStep configurator
pad layout for your system)
• NOTICE - Four anchor bolts required for stair unit when
six step or greater.
• Layout area for location of your ErectAStep system
using measuring tape and chalk lines, keeping anchor
lines square and parallel.
• Drill or wet set anchor bolts in the mathematically correct
location prior to assembly. Follow any curing
procedures recommended by your concrete/anchor bolt
supplier.
• Using a level slab/foundation is recommended for
anchoring the ErectAStep unit to achieve a good contact
point between the bottom of the stairs/supports and the
concrete in lieu of utilizing leveling anchors and shims.
• Once pad layout is complete and you are ready to
assemble unit, continue with instructions. Assemble unit
on anchor bolts starting with supports, stairs and then
connecting platforms, handrails, gussets, etc.
• NOTICE - Do not assemble unit off of anchor bolts and
then lift onto them. System should only be assembled in
its final location. Never move an assembled system.

STACKING COMBINATIONS
STACKING
Three thru six step towers, ladders and stairs can be
stacked to create systems taller than six steps. See
samples below:
7 step = 4 step + 3 step
8 step = 5 step + 3 step
= 4 step + 4 step
9 step = 5 step + 4 step
…..
12 step = 6 step + 6 step
= 4 step + 4 step + 4 step
Recommended larger step sections positioned at
bottom of stacked sections.
WARNING!
15 step is maximum size without special stair rules.
For 16 step thru 20 step, see ErectAStep configurator
or sales representative. Failure to adhere to special
stair rules may result in death or serious injury.
4-29-16
NOTICE:
One and two step towers, ladders and stairs are not
used in stacking.

PLATFORM SLOT USAGE
Platforms are designed with slots to
allow for adjusting positions of handrails
and stair units.
CAUTION!
Certain configurations can create pinch
points.
Platform slot design allows for mounting
adjustments to deter pinch points.
Handrails or stair units can make use of
these slots in order to avoid pinch points.
NOTICE: Be sure to account for dimensional
change in anchor bolt layout when sliding
stair unit over.

SYSTEM DESIGN
APPLICABLE OSHA REGULATIONS DESIGNED TO:
OSHA 1910.23(e)(1) A standard railing shall consist of top rail, intermediate rail, and posts, and shall have a vertical height
of 42 inches nominal from upper surface of top rail to floor, platform, runway, or ramp level. The top rail shall be smooth surf aced
throughout the length of the railing. The intermediate rail shall be approximately halfway between the top rail and
the floor, platform, runway, or ramp. The ends of the rails shall not overhang the terminal posts except where such overhang
does not constitute a projection hazard.
OSHA 1910.23(e)(5)(iv) The mounting of handrails shall be such that the completed structure is capable of withstanding a
load of at least 200 pounds applied in any direction at any point on the rail.
OSHA 1910.23(e)(6) All handrails and railings shall be provided with a clearance of not less than 3 inches between the
handrail or railing and any other object.
OSHA 1910.23(e)(3)(ii) For pipe railings, posts and top and intermediate railings shall be at least 1-1/2 inches nominal
diameter with posts spaced not more than 8 feet on centers.
OSHA 1910.23(e)(2) A stair railing shall be of construction similar to a standard railing but the vertical height shall be not
more than 34 inches nor less than 30 inches from upper surface of top rail to surface of tread in line with face of riser at
forward edge of tread.
OSHA 1910.24(c) “Stair strength.” Fixed stairways shall be designed and constructed to carry a load of five times the
normal live load anticipated but never of less strength than to carry safely a moving concentrated load of 1,000 pounds.
OSHA 1910.24(d) “Stair width.” Fixed stairways shall have a minimum width of 22 inches.
OSHA 1910.24(e) “Angle of stairway rise.” Fixed stairs shall be installed at angles to the horizontal of between 30 deg.
and 50 deg. Any uniform combination of rise/tread dimensions may be used that will result in a stairway at an angle to the
horizontal within the permissible range. Table D-1 gives rise/tread dimensions which will produce a stairway within the
permissible range, stating the angle to the horizontal produced by each combination. However, the rise/tread combinations
are not limited to those given in Table D-1.
Angle to horizontal Rise (in inches) Table D-1 Tread run (in inches)

OSHA 1910.24(f) “Stair treads.” All treads shall be reasonably slip-resistant and the nosings shall be of nonslip finish.
Welded bar grating treads without nosings are acceptable providing the leading edge can be readily identified by personnel
descending the stairway and provided the tread is serrated or is of definite nonslip design. Rise height and tread width shall
be uniform throughout any flight of stairs including any foundation structure used as one or more treads of the stairs.
OSHA 1910.144(a)(3) Yellow. Yellow shall be the basic color for designating caution and for marking physical hazards such
as: Striking against, stumbling, falling, tripping, and “caught in between.”
OSHA 1926.451(f)(16) Platforms shall not deflect more than 1/60 of the span when loaded.
