Connector Kits

Connector Kits are available for all of our domes. Those who want to cut their own lumber can save considerably.

You can build your own dome by supplying your own lumber for the struts, and make it any size convenient for your needs. Connector Kits are available for all the domes and Base Options when applicable. Connector Kits apply to wood domes.

The Connector Kit includes:

Directions for sawing boards- measurements and angles for a particular dome size.
Standard or heavy duty pvc or metal (aluminum or steel) Connector Hubs - our patented connector design that makes low cost do-it-yourself domes possible.
Instructions for sawing, drilling and waterproofing lumber for dome struts.
Illustrated assembly instructions. Parts are identified by letter, number, etc.
All necessary hardware.
Instructions on applying dome cover materials.

Connector Kit Prices

Prices are based on the dome size and type.

See price charts

Standard: schedule 40 pvc

Upgrade: schedule 80 pvc recommended for 25 ft and larger domes, or smaller requiring extra strength. Thicker and stronger than sch. 40

Options: Steel, for home or extra strong and permanent construction, has iron oxide anti-corrosion finish. Aluminum- high strength low corrosion type with powder coat (TGIC polyester).

Quick connecting feature: applies to wood domes only. Typically adds 15% to cost, with more hardware and mfg. labor involved. Very good for easier and faster assembly, or repeated assembly/disassembly.

You get plenty of drawings, charts, diagrams and specifications for making your dome with the Connector Kit, such as this exploded illustration of the 14 ft 2 x 4 Tetra-Dome:

Super Poly

Translucent woven poly used as an effective and inexpensive dome covering. The Super Poly Kit for dome covering includes:

Super strong long lasting 7,10.5 or 13 mil woven polyethylene with protection from UV sunlight deterioration.
Cinchstrap lath, a white vinyl strip lath used to protect the poly from wear and overheating.
Polyfastener, locking channel for removable sections of poly, used for window openings or secure attaching. Length supplied for 2 triangle openings in the "Super Poly Kit".
Exterior and interior hub covers (polygon plates, made from acrylic sheet like Plexiglas brand, usually white but may be any std. color) with attaching hardware.
Cutting patterns and instructions for installing the Poly Kit. Cutting patterns are similar to the dome paper model plans, scaled to your dome size and arranged to fit on standard 10 or 12 ft widths of the Super Poly.

Tools required for applying super poly are: staple gun, glue gun, trim knife.
The Super Poly can be successfully attached to the domes without using above mentioned accessories, which can also be purchased separately.

Using Polyfastener for attaching the Super Poly, easily removeable for dome windows:

Insert strip
Polyfastener channel
Super Poly
Roller tool

#2 Polyfastener Channel is attached to the 2 x 2 or 2 x 4 frame using staples or flat head screws. The roller tool forces the insert strip into the channel, locking the poly material. A hook tool is also supplied for removal.

Super Poly shown with vinyl coated fiberglass wire screen, used for shade cloth over the domes during seasons of high temperatures to reduce interior heat. Slightly enlarged to show detail. Many varieties of shade cloth are available.

Base Options

An extra level of triangles added to raise height of the domes. Consists of all necessary struts, Connector Hubs, hardware and instructions. Depending on the dome size, the Base Option will raise your dome approximately 3 to 5 feet and add a significant amount of useable interior space. It may also be a Vertical Base Option, best when adding a rigid siding such as plywood or polycarbonate greenhouse glazing. See Octa-Dome

White coat - white elastomeric roofing paint brushed on + white exterior latex sprayed on; good for adding light to greenhouses.
All necessary hardware: nuts, bolts, washers, screws; zinc plated for rust resistance or upgrade to rust proof "galvanized" hardware (best in moist environments).
Illustrated step-by-step instructions
A paper model plan of your dome to aid in assembly

We offer our domes at a SUPER VALUE price for a remarkable product that you will use and enjoy for many years. Domes are very rigid and will support weight such as shelving, hanging baskets, lights, snow, etc. Our domes are designed to be easily assembled with common hand tools. Lumber used is 2 x 4, (or other as specified) white and yellow pine; best grade available. Clear oil based weather sealer/preservative is applied to all lumber as a standard procedure. (Keep freezing moisture out of your wood!) An optional weather protector is available, "White Coat" that is a coating of elastomeric paint, brushed on, followed by exterior grade white latex paint sprayed on. Domes made from steel (emt tube) or aluminum (hollow square or round extrusion) are an alternative to wood strut domes that we can manufacture. Write us about other dome ideas such as pvc, bamboo, etc.

Domes are also completely portable, taken apart piece-by-piece or by sections (or lifted as a unit with several men or proper equipment). Our exclusive Construction Connector System makes assembly quick and easy with only basic mechanical skills required. Actual assembly (the basic frame) takes approx. 3-8 hours for most domes; depending on dome type and size, number of workers, and if regular or power tools are used (you can use an air powered ratchet for wood dome assembly).

Shipping for a complete dome Frame Kit depends on destination and weight. Smaller domes may be shipped by UPS in several boxes. For instance: 1 x 2 and 2 x 2 domes to 20 ft. (most cases), steel tube domes/spheres. Larger domes (2 x 4, 2 x 6) may weigh several hundred lb. We will use the most economical freight delivery from our manufacturing facility in Austin, Tx. to your location. Send your Zip Code for an estimate. A cost saving option is renting a truck or trailer and doing the transporting yourself.
