At the request of the customer, we went looking for a source of one piece solid brass rings. The rings are used at the end of a guy line to attach to the stake. This keeps ropes cleaner (for later folding into the tent) and allows the ropes to tighten and loosen easier. Although we can find no historical basis for their use, they sure work great.
Brass Rings: 1 1/2″ diameter
We also sew brass rings into the stake locations for any tent. No more loops to wear out ever. $5.00 for each location.
