Panel holder on wheels made of 6 mm thick steel.
The wheels are made of solid, puncture-proof rubber with a very high density, including a ball bearing with an inner diameter of 17 mm.
The central axle is solid to reinforce the whole structure. The tire is sized 2.50-4 and the rim is riveted to prevent any disassembly of the assembly. We have also added two non-loosening nuts to ensure durability over time. The maximum width that can fit into the U is 105 mm, but it is recommended to keep 100 mm for proper operation.
It can also serve as a glass holder or tool holder.
