Accessory kits include waterproof couplers, cable clips, anchor bolts, washers, and labels. Verify thread specs and flange hole spacing before install to avoid field re-drilling.

Follow 'in-first, out-last; top-in, bottom-out' routing for waterproof joints; torque per manufacturer — overtight strips threads, undertight leaks. Relieve cable stress at entries.

Keep a ~5% spare parts pack per crew and photo-document concealed work for warranty traceability.

Roughly 80% of street light failures trace to connections and waterproofing — parts quality equals install craft.
