Specification

Rotationally Molded Plastics
All Rotationally Molded Products are manufactured from medium density polyethylene (UV-stabilized color).
The tensile strength of this material is to be 2500 PSI as dened by ASTM D638. The nomimal wall thickness
will be .250” (¼”). All rotationally molded products shall meet or exceed the following specications:
Melt Index (ASTM D-1238); Density (ASTM D- 1505); Tensile Values (ASTM D-638); Flexural Stiness (ASTM
D-747); IZOD Impact Strength (ASTM D256); Vicat Softening Point (ASTM D-1525); Brittleness Temperature
(ASTM D746); Shore Hardness (ASTM D2240).
Blow Molded Plastics
All Blow Molded Products are manufactured from high-density polyethylene. The nominal wall thickness will
be .200” . All blow molded products shall meet or exceed the following specications:
ASTM-D 1248 Type III, Class A, Category 5; Melt Index (ASTM D-1238); Density (ASTM D- 1505); Tensile Values
(ASTM D-638); Flexural Modulus (ASTM D-790); IZOD Impact Strength (ASTM D256); Brittleness Temperature
(ASTM D746).
HDPE Components
Climbers shall be precision cut from a single solid sheet of .59” thick UV-stabilized extruded high-density
polyethylene. All edges shall have radiuses and all corners rounded for safe play.
Hardware
All nuts, bolts, and washers, with exceptions noted, shall be stainless steel Grade 304 in varying lengths, with
a vandal-resistant button-pinned head conguration and factory-applied locking patch. When allowed a
72-hour cure time, the locking patch will prevent the bolt from loosening without at least 4 times the instal-
lation torque. UltraPlay will supply the special tool required to turn vandal-resistant hardware with each
shipment.
Uprights – Steel
The posts shall be 3 1/2” O.D. 13-gauge galvanized steel tubing. Entire post is powder coated after fabrica-
tion.
