HANDRAILS

All handrails, unless otherwise stated, shall be constructed of knurled aluminum of not less than 1-1/4" in
diameter. All railing shields and brackets shall be chrome plated, and shall be bolted to the body with
stainless steel bolts. The lower bracket on all vertical handrails shall have a drain hole drilled in it at the
lowest point.

The following handrails shall be provided on the apparatus:
There shall be a vertical handrail installed at the left rear of the apparatus.
There shall be a horizontal handrail installed above the rear compartment below the hose bed.
FUEL TANK GAUGE ACCESS PANEL
There shall be a removable panel provided in the rear compartment to allow for access to the fuel tank
gauge without removing the fuel tank.

LICENSE PLATE BRACKET
There shall be a license plate bracket mounted on the rear of the apparatus. A clear LED light shall be
incorporated into the bracket.

REAR STEPS TREAD PLATE OVERLAY
There shall be a tread plate overlay on the vertical area behind the left side rear steps of the apparatus.
Overlays shall be totally insulated from the apparatus with nylon shoulder washers that extend into the
hole that is drilled into the body. Stainless steel cap nuts shall be employed where bolts may damage
equipment or cause injury. After painting and final construction overlays shall be additionally sealed at the
edges with a caulking compound.

QL-12 ELECTRICAL SYSTEM
Wiring harnesses shall be the automotive type, engineered specifically for the builder's apparatus, and
shall meet the following criteria. Under no circumstances shall diodes, resistors, or fusible links be located
within the wiring harness. All such components shall be located in an easy to access wiring junction box
or the main circuit breaker area. All wiring shall meet white book, baseline advanced design transit coach
specification and Society of Automotive Engineers recommended practices. It shall be stranded copper
wire core with cross linked polyethylene insulation complying with SAE specification J1128. Each wire
shall be hot stamp function coded every three inches starting one inch from the end and continuing
throughout the entire harness. In addition to function coding, each wire shall be number, color, and gauge
coded.

Wire harnesses shall be wrapped with a high abrasion and chemical resistant thermoplastic polyester
elastomer coated polyester yarn for braiding constructions of electrical wiring systems. The braid yarn
shall have a minimum tensile strength of 15 lbs. before breaking and have a maximum of 20% elongation
before breaking. Temperature properties for the yarn shall range from a minimum 280°F (138°C) service
temperature to a maximum -112°F (-80°C) brittleness temperature with a cold flex tolerance of at least -
49°F (-45°C).
