Dimensions: 40′ X 100′. We do need to have an additional 7-10 feet on each side of the canopy for set up. You can add sidewalls with or without windows. These are $25 a piece for each 20 ft section. Item Description: Canopies are a must when events are held outdoors. Colorado weather can be unpredictable, so avoid weather issues or cancellations with a tent. We also have sidewalls, misting fans, and heaters to rent to help with weather concerns. This size canopy is perfect for large events as it can hold anywhere from 300 to 650 people depending upon what type of seating you wish to have for your attendees. We also have tables (Round, Banquet and High top), chairs and linens to rent that can help complete the interior of the tent. Additional Information: The base price for a 40’ x 100′ tent on grass is $3,780. Base price for Concrete set ups is $4,980. Depending on situation and area, there may be additional fees for permits. Set up/tear down and delivery fees vary. Please submit your cart order and we will reply with the total fees. If you would like sidewalls, let us know on the message option within your order. If walls are needed, please specify solid or cathedral windows. All orders that contain one or more canopy(s) 20x20 or larger will also include a delivery fee regardless of the area. Please contact the office to calculate a delivery rate.
