I. FINISH: The standard finish on this wireway is gray polyester powder over a cleaned and phosphatized surface. This surface
may be further finished with lacquer or enamel.
II. ASSEMBLY: To assemble most wireway sections and
fittings, simply place a gasket between
flanges and install screws and nuts as
shown in detail 1.
III. TELESCOPE FITTING:
A. To Adjust Telescope Fitting:
1. Assemble parts on body of telescope fitting in correct order as shown in detail 2.
2. Insert body of telescope fitting into straight section and adjust to the desired length.
3. Position gasket retainer against flange of straight section and force the gasket inside the gasket retainer and
against the flange.
4. Position compression ring against gasket retainer and install screws and nuts as shown in detail 3.
5. If wireway is to be used as ground, provisions must be made for grounding continuity across telescope fitting.
B. To Anchor Telescope Fitting at Desired Extension:
1. If the telescope fitting is used in a vertical position to support the wireway above, or if the telescope fitting
is otherwise subjected to a material axial load, means to support such a load may be provided by one of two
methods:
Method I: With the telescope fitting at the desired extension,
drill .25 inch diameter holes through each side of the straight
section and through the telescope fitting. Install .25−20x.5
screws through the holes from the outside and install cap nuts
and lockwashers as shown in detail 4.
Method II: Replace screws in two diagonally opposite corners
of flanges with .25−20 threaded rods. Assemble rods, nuts,
and washers as shown in detail 5. After tightening the nuts,
measure the length of the extension to be sure it is the same
on both sides.
