associated with this project and deemed as reliable. Conditions directly affecting the product or its
installation must be field verified.
Drawing Review - Shop drawings are produced to assure compliance with the contract. Drawings must
be reviewed by the Owner/Architect/Contractor, or other appropriate owner's representative. If drawings
are correct, mark them as such; if incorrect, note corrections to be made and return to KI for corrections.
Any deviations from the contract included in the shop drawing must be approved in writing from the
Owner/Architect/Contractor. Drawing must be signed by authorized personnel including title, company or

Materials
A. Frames
Sequence HD Seating “Basic” rectangular frames with tablet arms, floor-mounted or riser-mounted base
plate shall be 6” x 8” 11-gauge stamped steel flange with 1/2” diameter anchoring holes pierced at each
corner. Pedestal column shall be 11-gauge, 1-1/2” x 2” seamless tubular steel upright welded to the base
plate. The vertical column on the floor-mounted base shall extend down through the base plate and shall
be welded around the vertical column at the pierced opening in the base. For added strength, a steel
strap shall be welded across the bottom of the vertical column and welded to the bottom of the floor
flange. The vertical column shall be capped with a stamped steel yoke cover to support the beam. The
stamped steel yoke shall be welded to the seat spider. Four nuts shall be welded inside the steel yoke to
accept screws from the base assembly to lock the seat and support beam firmly into place. The bases
shall be positioned directly under the center of the seat. The seats shall be joined in sequence along an
11-gauge, 1-1/2” x 2” seamless steel tubular beam cradled in the yokes on top of the bases. No holes
are required to be drilled in the horizontal sequence beam to enable the seats to be positioned on the
bases at any point along the beam. Sequence HD beams shall be furnished in any length with beam
segments joined inside a yoke with beam-ganging plates that lock the two segments of the beam
together. Seat frame shall be made of 1” square, 13-gauge steel tubing welded to the back-flex
mechanism tube. The seat frame shall be supported by, and welded to, the beam-mounting yoke, made
of 11-gauge steel. Seats not located directly above a base shall be fastened with a yoke only. Plastic
flange covers shall be furnished on the floor-mounted bases.
B. Tablet Arms
The tablet support shall be 1” x 2” rectangular 14-gauge steel tubing. The support shall be welded to the
beam-mounting yoke, made of 11-gauge steel. The tablet mechanism shall be a self-storing, one-motion
mechanism. The mechanism consists of a pivot arm, pivot mount bracket, and support bracket
constructed of 7-gauge steel with controlled 90° up-and-down rotation. The tablet arm shall store
underneath the seat at a vertical angle, without interfering with the seat.
The tablet board shall be made from 13 ply, 18mm Baltic birch plywood, sanded, sealed, and lacquered
on all edges. The writing surface is .040 thick high pressure laminate. The backing is .04 thick phenolic
backing sheet. Medium Tablet – 8.8” x 13.63” x 19.3”.
C. Shells
Torsion on the Go! Seat and Backrest: Seat shall be a two-piece construction of molded plywood
upholstery board with a molded compound-curved polypropylene shroud with a textured finish. Seat is
always upholstered with 1-3/4” foam applied to the molded plywood upholstery board, upholstered with
fabric. Backrest is poly. The backrest is molded compound-curved polypropylene with a textured finish.
The gravity-lift automatic seat return is accomplished by a counterweight, with no springs or mechanical
actuators to fatigue or fail. Two .079” thick, 14-gauge welded steel backrest supports attach the backrest
to the torsion mechanism. A cast steel bushing is welded onto each backrest support, capturing the
Torsion back-flex springs. The back flex is achieved by the torsion mechanism. It consists of two flat
torsion springs captured at both ends by steel bushings that are pinned to the backrest supports. The
torsion mechanism creates gradually increasing resistance over the full 12° of back flex or approximately
6”.
D. Colors
Frame finishes - Powder-coated finish is standard on all frames. Plastic trim components match the four
standard powder-coated colors. Tubing end caps and seat-return bumper in black only. Standard KI
fabrics available; C.O.M. (customer’s own material) fabrics require factory approval. Refer to KI fabrics
and finishes and Color Addendum for standard color choices.
