This kit is ideal for those who need a strong framework, but may need to take it down periodically. This is the perfect option for trade show use, and an excellent choice for indoor or outdoor cages. This kit includes all the fittings, set screws, and instructions you'll need to set up your frame.
You will need to supply 1-3/8" galvanized tubing, or equivalent.

1-3/8" galvanized tubing is more than twice as strong as 1" EMT conduit, and more that 3 times as strong as 3/4" EMT conduit. Since this tubing is commonly used as the top rail for chain link fencing, you can find it at your local home improvement store such as Lowe's™ or Home Depot™, or you can source it through your local fencing supplier.
