30' x 40' Party & Canopy Tent Premium Blockout Sidewall Kit

Few things are more disappointing than spending months planning a big event only to have it ruined by wind, rain and bad weather. You may not be able to control the weather, but you can control how prepared you are to handle the unexpected with our 30' x 40' Premium Waterproof Blockout Sidewall Kit. Whether you're looking to add some protection from wind and other seasonal elements, need to replace old, existing sidewalls or really just want to add some privacy for your guests, our 30' x 40' Premium Blockout Sidewall Kit make the perfect addition to your outdoor party or canopy tent.

Cathedral or Window Sidewalls are the best of both worlds, as they offer protection coming from outside of your event tent, but also allow an elegantly-designed window to see outside your tent.

Our 30' x 40' Premium Blockout Sidewall Kits are constructed from 14oz thick premium blockout PVC waterproof vinyl, are UV resistant and also resistant to mold and mildew. Easily retrofit your existing party tent with our premium blockout vinyl sidewalls that simply attach with plastic clips. They also feature strapping for staking and securing to the ground (color varies by size).

Fabric Translucency: Blockout vinyl sidewalls will prevent all light sunlight from penetrating through the material, providing maximum protection from the sun and superior privacy.

Please Note: Stake strapping color varies by size. It is not recommended that these sidewalls are staked to the ground during heavy winds to prevent possible damage to your equipment. It is recommended that you stake your sidewalls the day of your event so that they can be supervised.

Warranty Information: Our vinyl canopy tents, vinyl tops, and vinyl sidewalls come with a 1-Year Warranty against manufacturer's defects. Warranty does not cover improper installation or misuse. Warranty does not cover wind whip or wind crack damage from the usage of our canopy tents in temperatures below 40 degrees Fahrenheit.
