DO NOT ALLOW USE BY CHILDREN or people unable to understand
the risks and to safely adjust the desk height.
MAINTAIN >1” (25mm) GAP ABOVE OBJECTS ON DESK AT MAX
HIEGHT AND BETWEEN THE DESK & ADJACENT OBJECTS.
Locate desk, accessories, and nearby objects to allow movement of
desktop through full range without pulling cords, trapping body parts,
or colliding with anything (shelves, electrical plugs and cords, door
knobs, window sills, storage cabinets, etc.)
CRUSH HAZARD - DO NOT PLACE FEET, LEGS OR OTHER BODY
PARTS ON OBJECTS PLACED UNDER TABLE TOP OR BELOW
MODESTY PANEL.

loose parts. Only repair with Steelcase authorized parts and methods.
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a class B digital device pursuant to Part 15 for FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the

RISK OF SERIOUS INJURY:

DEPTH
POTENTIAL FOR INJURY
:
The use of worksurfaces that do not comply with the Steelcase defined criteria and limitations could cause personal injury or p
roperty damage due to pinch
points, instabilit
y
, or other problems.
POTENTIAL FOR NON-COMPLIANCE: The use of work surfaces that do not comply with Steelcase criteria VOIDS any Steelcase claims of
compliance with ANSI/BIFMA, UL, LEED,
or other applicable requirements. The use of non-Steelcase work surfaces on Steelcase adjustable-height bases may NOT be accept
ed as compliant to municipal electrical codes or
OSHA federal workplace standards, because this use may not create an NRTL (UL, ETL, etc.) listed product.
Steelcase is not responsible for the ultimate determinations of compliance
for height-adjustable bases with non-Steelcase work surfaces. Steelcase assumes NO liability for lack of standards compliance
in these instances.
WARRANTY RESTRICTIONS: The use of non-Steelcase supplied work surfaces VOIDS all Steelcase warranties, expressed or implied.
DISCLAIMER: The use of non-Steelcase work surfaces is NOT recommended. Any use of a non-Steelcase work surface requires additional investigation by the customer regarding the
appropriateness for use. It is the sole responsibility of the customer to determine the suitability and safety of the selected work surface construction and attachment means. The following
information is provided as a guideline, but does not address all potential issues. Customers should seek professional guidance as to the appropriateness of their chosen work surface.
FOLLOW ALL WARNINGS PROVIDED FOR BASE + WORK SURFACE.
MANDATORY REQUIREMENTS REGARDLESS OF WORK SURFACE MATERIAL OR CONSTRUCTION:
FASTENERS: Adjustable-height bases include fasteners intended for use with Steelcase work surfaces.
These fasteners may potentially also be suitable for work surfaces meeting the following criteria:
Medium-density or higher particleboard or fiberboard cores with High-pressure laminate (HPL), Low-
pressure laminate (LPL) or veneer & backers
Thickness of .984” (25.0 mm) or greater
Fasteners located a minimum distance of .984” (25.0 mm) from any edge
Any other work surface construction will require different and/or additional fastening means and these means
must be determined by the project’s designer, architect, or engineer. For example, solid-surface materials
should use appropriate threaded inserts and corresponding fasteners or similar attachment means.
In all cases, all fastener locations provided in the base attachment features MUST be used (e.g. if attachment
plate has 6 screw holes, all 6 holes must be used for attachment).
FLAMMABILITY: Any worksurface or similar large part > 10ft ^ 2 must have a flame spread < 200 and
a smoke developed index < 450 when tested per UL 723.
SHARP EDGES: All accessible edges of the work surface must meet 1439 test for sharp edges.
DIMENSIONAL LIMITATIONS:
Work surface depth not to exceed 36.0” (914.4 mm)
Work surface overhang (distance from side of support cantilever to edge of work surface) must be
greater than .984” (25.0mm) and may not exceed 15.0” (381 mm)
Work surface overhangs larger than .984” (25.0mm) are not allowed on widths < 64.0” (1625.6 mm)
Work surface overhangs between .984” (25.0mm) and 15.0” (381 mm) may exist on one side only for
tops that are ≥64.0” (1625.6 mm) and ≤71.645” (1820.8 mm)
Work surfaces larger than 71.685” (1820.8 mm) must have overhangs larger than .984” (25.0mm) on
at least one side, but may not exceed 15.0” (381 mm) on any side
Maximum work surface width may not exceed 101.685” (2582.8 mm)
