Choosing a Safe Tie in Point (TIP)
Selecting a tie-in point (TIP) is one of the most important aspects of safe and efficient tree climbing, but there have been very few studies that have tried to figure out what an appropriate size is. Over the last several years, we’ve studied the loads a TIP experiences as a climber ascends, descends, limb walks, swings, or falls—this information is critical to understanding how large the diameter of the TIP should be. Is it safe to use the old rule of thumb by choosing a TIP that had a diameter as least as large as your wrist?
