3/8-16 Zinc Round Base T-nuts
One rung.
Our order just shipped via SEA today. 8/25/20 We expect delivery early to mid-October. The Round base version will be in stock this week.
3/4" seems to be the standard small campus rung. Good as a traditional low wall angled campus rung.
2" is huge. Almost feels like a jug. Big moves on these or fantastic intro campus board rungs in to the world of campus training. This climbing rung is 16 inches wide.
