A vertical pipe driven into the ground and guyed with wires is a great place to mount a time-lapse camera system. A pipe cap attachment is available as a mounting option, where a ball stud is welded to a cap. Both pieces are stainless steel, allowing the assembly to be welded directly to a steel pipe, or screws may be drilled/tapped/inserted through the cap and pipe.
The standard pipe cap attachment will mount to NPS 1.5”, NM 40mm, or NM 40.8mm scaffolding pipe, but other sizes can be provided.
Note that unlike the other attachment options made from aluminum, the pipe cap attachment is made from stainless steel. This assembly can be welded to any steel structure, not just pipe.
