Important Notes

- Temperature Range: Recommended for prolonged use between -40°F (-42°C) and 150°F (66°C).
- Arms & Adders: If arms are ordered separately, pricing will differ compared to purchasing a complete assembly. Adders may apply (add the option’s list price to the closer list price and take standard discounts).
- Finish Availability: Accessories may not be available in all finishes; confirm availability and lead time.
