Create a curved seated riser system with this riser stage pie unit!
NPS Portable Stage Pie Units are the building blocks for creating the perfect riser for your school performances and assemblies. Users are supported by a heavy-duty, 16-gauge steel, black powder-coated frame. The premium 3/4" thick plywood deck is durable and features a 1/8" thick tempered hardboard surface. Legs are constructed with 14-gauge steel tubing and feature simple and safe spring-loaded locking mechanisms allowing for quick set-up assembly and folds up easily for manageable portable storage.
This stage pie unit offers a secure Standard Uniform Load Rating of over 200 lbs per square foot. High-impact plastic glides will ensure floors are protected from damage. Firmly welded ganging devices let users combine equal-height stages to create a large single stage platform or assemble different sizes to create choral or band riser configurations.
Please Note: Guardrails are recommended while using any stages or risers to ensure safety.
Constructed with a ¾" thick solid plywood
core, the riser shall be surfaced with one of
Option 1: Carpet, Option 2: 1/8" thick tempered hardboard. The edges of the platform shall be routed
to allow the frame to fit flush with the top
surface and cover the ends of the carpeting.
16 gauge, 1-13/16" high formed steel
channel frame shall be reinforced with 16
gauge steel angle welded to the inside of the
channel. The angle shall provide a continuous
support to which the decking is secured
with screws placed a maximum of 9" apart.
The frame shall completely enclose the top,
bottom and edges of the decking perimeter
preventing the decking from becoming loose
and damaged. All areas where frame parts
are joined together shall be reinforce with
steel plates attached with rivets.
Each leg structure shall be constructed
of 1.05" diameter, 14 gauge steel tubing
capped at the point of floor contact with
high impact plastic glides. The vertical
load bearing members shall be joined at
the top by full width, steel tube to provide
maximum support to the stage deck. The
top of each leg assembly shall fold open
and closed, using 16 gauge steel saddle
clips that are secured with at least four
screws. Leg assemblies shall be braced
by friction type braces, equipped with a
spring locking device to secure the legs in
the open and closed position. Braces shall
be secured to the leg assembly with rivets
and to the deck using 8 screws installed
through the decking. Legs shall open and
close using only one hand. Gravity ring
type brace locks are not acceptable.
Stages and risers shall be equipped with
drop-in couplings that allow units of the
same or different heights to be joined
together. All ganging devices shall be
permanently secured to each unit. Ganging
devices that is not permanently attached
are not acceptable.
All metal parts are to be finished with a
black thermofused epoxy powdercoating.
All metal parts shall be designed to carry
a uniform live load of at least 200 lbs. per
Stages and risers shall be capable of being
completely set-up and taken apart quickly,
without the need for tools, by two people
of average strength.
