At the end of the 6' tapered oval aluminum luminaire mast arm mounting bracket, the pole shall sustain a vertical load of 100 pounds applied with the vertical deflection of not more than 5% of the bracket length; at the same point the pole shall sustain a horizontal load of 50 pounds applied in either direction with a horizontal deflection of not more than 7-½% of the bracket length.
7. Pole Identification
Refer to “Exhibit A”, Framing Requirements.
The manufacturer’s name or logo, catalog number and date of manufacture (month/year) shall be permanently tagged, embossed or stamped on the face of the pole approximately 6" above the wire access handhole. Tag identification shall remain legible after pole finish is applied. Tags shall be secured with aluminum pop-rivets. The stem of each rivet shall not protrude past the outer lip of the rivet causing a potential safety hazard.
8. Flame Resistance
The pole shall be flame resistant in accordance with ASTM D 635.
9. Pole Cap
Each pole shall include a cast aluminum, hot dip galvanized steel or heavy duty District approved fiberglass pole cap.
Caps shall fit snugly and shall be shipped securely attached to poles with at least two stainless steel or galvanized securing screws.
Metal caps shall not be painted. Fiberglass caps shall be same finish as pole.
10. Mast Arm Attachment Provision
Refer to “Exhibit A”, Framing Requirements.
The pole shall be delivered pre-drilled as specified to accommodate a 6' tapered oval aluminum luminaire mast arm with a 24" rise.
11. Wire Access Handhole
Refer to “Exhibit A”, Framing Requirements.
Each pole shall have one 4" wide x 12" high oval-shaped wire access handhole on the face side of the pole. The center of each access handhole shall be located 4'-0" above the Final Grade and 6'-0" above the center of the cable entrance hole.
Each handhole shall be provided with a molded or cast access cover plate made of aluminum, hot dip galvanized steel or District approved heavy duty composite, same finish as pole. The access cover plate shall fit snugly to pole surface without gaps or flexing to restrict access into the pole without removing the cover. This access cover plate shall be secured to the pole with two, ¼"-20 UNC stainless steel vandal-resistant 5/32" hexagon pin socket screws that thread into a District approved non-conductive back bar inside the pole in order to hold the cover snugly to the pole when the screws are tightened. The handhole cover screws shall have some means of a stop on the inside end to prevent accidental removal from unscrewing too far.
When the cover is removed for access inside the pole, the cover shall be held captive to the pole by means of a coated stainless steel tether wire, approximately 15" in length. Tether wire shall be securely attached to the pole with an aluminum pop-rivet and backing washer. The location of the pop-rivet on the pole shall be just below the handhole opening and shall not conflict with the access cover. The aluminum pop-rivet and backing washer shall be installed in a quality workmanship manner to allow the cover to hang from the tether inside the pole and to prevent the tether from being pulled loose and the cover from being accidentally dropped inside the pole. The stem of each rivet shall not protrude past the outer lip of the rivet causing a potential safety hazard.
The manufacturer’s name or logo shall be permanently embossed or stamped on the face of access cover plate.
12. Cable Holes
Refer to “Exhibit A”, Framing Requirements.
The pole shall have one round shaped cable entrance hole near the top on the face side of the pole that will provide direct access to the inside of the mast arm. This hole shall have an inside dimension of 1-½" with a tolerance of +½"/-0" after the grommet is installed and be centered between the mast arm mounting holes and 9" below the top of the pole.
The pole shall have one oval shaped cable/conduit entrance hole centered 36" from the bottom of the pole, 72" below the center of the wire access handhole specified in Section 11 and positioned 180° from the face. This hole shall have a minimum inside dimension of 3" wide x 6" high.
All cable hole openings shall be fitted with grommets to protect the electrical conductors from damage due to the abrasive edges of the holes. All grommets shall be installed with an adhesive to secure them during shipping, handling and installation of the pole.
The dimensions of all cable hole measurements specified above shall be after the grommets are installed.
13. Pole Stability
Refer to “Exhibit A”, Framing Requirements.
Pole shall have a permanently installed anti-rotational device (flared base, or other District approved permanently installed method) to provide resistance to rotation and pullout.
