Our HDPE Arch Bases are the perfect way to build the larger arches and feature our innovative sliding pixel strip holders. The HDPE Arch Bases are designed for either 1.75″ or 2″ outer diameter HDPE tubing that is sold by McMaster Carr. The design utilizes 1/2″ EMT conduit for the horizontal bracing and 1/2″ PVC perpendicular stabilizing legs. This hybrid approach adds rigidity to the bases where you want it on the horizontal span and retains flexibility within the legs to reduce stresses on the bases. The bases are designed to allow pigtails to pass inside the base and exit along a channel on the bottom of the base. An internal zip tie tunnel locks the pigtails in place so they stay contained in the channel. The pixel strip holder securely holds the strips without using any screws or zip ties and allows for a small bungee cord to supply tension. A front zip tie tunnel is then used to cinch the bungee in place and hold the tension. The top of the arch base also has a receptor that holds the pixel strip holder so that it remains as close as possible to the inside arc of the HDPE tubing. Includes STL files for the arch bases and the pixel strip holder. More details on the arches below.
