All fittings meet or exceed physical properties of ASTM A1011 GR 33.
The pickling of the steel produces a smooth surface free from scale.

Finishes :

Fittings are available in:

Green Powder Coat (GR): Conforming to commercial standards for Powder Coating.
Electro-galvanized (EG): Conforming to ASTM B633 Type III SC1.

*** Perma Green finish is a commercial-grade finish, and as such, scuffs and scratch marks are to be expected. If a flawless finish is desired, it is recommended to apply matching touch-up paint. ***

All part drawings illustrate only one application of each fitting. In most cases, many other applications are possible.
The channels shown in the illustrations are P1000 (1-5⁄8″ square), except where noted otherwise.

Nuts and bolts are not included with the fitting and must be ordered separately.

Metric dimensions are shown in parentheses or as noted.
Unless noted, all metric dimensions are in millimeters and rounded to one decimal place.
