20' x 40' Tent Rental
A spacious high-peak frame tent that creates a seamless covered venue for larger weddings, corporate events, and outdoor gatherings
When a single 20' x 20' isn't enough, the 20' x 40' Tent delivers double the coverage in the same clean high-peak frame design. At 800 square feet, it seats up to 66 guests for a formal sit-down dinner or accommodates up to 160 for a cocktail-style reception — all under one connected structure. Equally at home at backyard wedding receptions, graduation celebrations, church festivals, and corporate outdoor events throughout Wentzville, MO and surrounding areas. All-day rentals start at $1,000.

Events That Call for 800 Square Feet of Covered Space

Setup, Installation & Important Details
⚠️ Missouri Dig Rite Requirement
Grass installations require underground utilities to be located before stakes are driven. Contact Dig Rite by calling 811 at least 3 business days before your event. This is a Missouri state legal requirement for any staked installation and is the responsibility of the property owner or event organizer.
🧱 Concrete or Hard Surface Installation
Events on concrete, asphalt, or other hard surfaces can be accommodated using weighted concrete blocks instead of ground stakes. An additional charge applies. Contact us when booking to confirm your venue surface and receive an accurate quote for your installation.
