Sport Dome General Specifications
Sport Dome general specifications
| Specification |
Details |
| Shape |
The shape of the Sport Dome is generally a rectangle but if needed we can manufacture custom shapes. If you need a Sport Dome in a custom shape, please give us a call and we will go over possible options with you. |
| Top & Wall Material |
We use a fire retardant vinyl coated fabric similar to that used to make white water rafts. The fabric itself weighs 18.5 oz per square yard and typically white is used as it is Fire Rated, easier to procure, reflects the UV rays better and is less expensive than other reinforced vinyls. We do not make the Sport domes with clear walls. Clear windows can be added as an option. |
| Anchor System |
The Sport Dome is anchored to a concrete slab or footer with anchoring sleeves (Redhead style) and a coated metal track system. The anchors are 1/2" diameter x 1-7/8" long and expand into the deck with the supplied center punch. Typical anchoring bolt spacing on the metal track is 1'. Note: A drain channel must be embedded inside the perimeter of the enclosure to control, divert, and drain water away from the playing surface during rain or snow. See Sample Plan 090 above. |
| Ceiling & Wall Height |
These dimensions will vary depending on the size of the dome. The larger the dome, the higher the ceiling and walls. Contact us to discuss a custom size. |
| Entries |
To enter or exit the Sport Dome we supply one "L" zipper and one airlock. If necessary you can order additional airlocks to fit your needs. |
| "L" Zipper Dimensions |
Vertical: 60" Horizontal: 40" |
| Inflation System |
The Sport Dome comes with the appropriate quantity of blower fans. These fans DO NOT HEAT the dome. Alternative heating options are available. Please call to discuss. |
Airlock Entry
Each Ameri-Brand Sport Dome comes with one airlock entry. The airlock is the main entrance for human traffic. We use airlocks rather than rotary doors because they are more cost efficient and rotary doors on inflatable structures are no longer legal to use in most states.
“L” Zipper Access
Each dome also includes one “L” zipper made from 2 zippers: one horizontal and one vertical. This opening is useful for moving long equipment into or out of the dome when it will not fit through the airlock.
The Sport Dome Blower System
Airflow and Blower Placement
Airflow is directed into the dome through a snorkel tube. The tube enters through the dome wall with a boot system that helps prevent air from escaping around the blower opening.
The blower and snorkel tube can be located anywhere around the dome perimeter except at a corner or directly in front of a door. See installed blower systems in the Sport Dome Gallery.

Made to Order
Each Ameri-Brand Sport Dome is custom made. We do not stock units in "standard" sizes. As each one is made to order, our customers always receive a product which was made exactly to their own specifications.
Production Schedule
After your order is received, it is placed on the production schedule and produced in the order it was received.
Welded Fabric Assembly
After the panels are cut into the right shapes, they are "welded" together to form the walls, ceiling, and corners of the unit. This process uses radio frequency (RF) sealing machines and hot-air heat-sealing machines instead of liquid adhesives. The welded seams produce an attractive enclosure with strong structural integrity.
These construction methods help your dome provide years of dependable service.
The Sport Dome Anchoring System
The Ameri-Brand Sport Dome is anchored by a series of concrete anchor sleeves (Redheads) and a treated metal track. The track holds the bottom of the dome walls securely to the deck.
Anchor sleeves are placed into the deck at about 1 foot intervals. These sleeves are 1/2" in diameter and 1-7/8" long. In the center of each sleeve is a 3/8" threaded hole which the bolts holding the track in place are screwed into.
To keep the dome secure in the track, a rope is heat sealed into the base of the wall. The rope limits vertical movement while allowing the dome to inflate fully without the material slipping at the base of the wall.
Aluminum track secures the dome wall to the concrete deck or footer.
If the Sport Dome is taken down during the spring or summer months, the track is removed to clear the deck. The sleeves remain and are flush with the surface of the deck, leaving no obstacles and allowing you to continue to play all year long. We even provide the Hole Plugs to keep debris out of the holes.
Inflation and Air Seal
The Ameri-Brand Sport Dome is an air-supported structure anchored to a concrete slab or footer. One or more blowers supply the air that keeps the enclosure inflated. A metal track runs around the entire perimeter and creates an air seal between the concrete and the dome hem.
Entry and Exit
Entry and exit are handled through an airlock or “L” zipper. If an entry is left open for an extended period, air loss will eventually cause the dome to begin deflating. This process takes a considerable amount of time on an average dome.
