Ultimate Arch Base

This listing is for Arch Bases only, sold in sets of two.

To purchase a kit with all of the custom parts required to make (1) SFL Designs Ultimate Arch (bases and back braces), click here. Hardware and pipe listed below can be obtained locally.

Arch Back Braces can also be purchased separately here (recommended 3-4 per Dual or Triple Arch Base Set)

These sets do not include the hardware or PEX pipe, but the links below will get you everything you need. Each base is sturdy on its own and interlocks with other arch bases using a 1/2" PVC pipe. That same interlocking pipe doubles as a wide footprint, keeping your arches from tipping forward or backward. Each base is also slotted for standard tent stakes so you can anchor it to the ground.

Our arch bases are made from PETG, a fantastic option recommended for seasonal use.  

Inside each arch hole is a small channel that lets you route your power cable from inside the arch out through the bottom. To keep tension on the pixel strip inside the tube, connect a small bungee to the strip and wrap it around the 1/2" EMT pipe that sets the spacing between bases.

Pipe

• 1" PEX is available at Lowe's, Home Depot, or Menards (Lowe's links shown here).
• Buy the pipe for the arches in 10' sections rather than a bulk roll.
• Cut or buy the EMT and PVC used for arch spacing and legs in 5' sections. If you use a different length of EMT, the measurements below won't line up.
• We cut our arch pipes to these lengths:
  • Outside pipe (Single, Dual & Triple): 108"
  • Middle pipe (Dual & Triple): 102"
  • Inner pipe (Triple): 96"

Drilling the EMT Pipe

• Align the markings on the pipe to the star in our logo on the bottom of the base, and drill while the pipe is inserted in the base.
• For the second hole, insert the EMT into the opposite base and secure it with a bolt. Then slide the pipe into the second base and, with it laying flat on the ground, start the hole. Once it's started, pick the base up and angle it for easier drilling.
