Here are his thoughts:<\/span><\/p>\n<ul data-spread=\"false\">\n<li><span><strong>Load Direction:<\/strong><\/span><span> Consider how the tree will be loaded\u2014in shear or at an angle. Attaching lower on the tree reduces the angle between the tree and the rock, leading to more shear loading and less leverage.<\/span><\/li>\n<li><span><strong>Sliding Prevention:<\/strong> Position the attachment point below a groove or branch stub to prevent sliding.<\/span><\/li>\n<li><span><strong>Rope Position:<\/strong><\/span><span> Avoid setups where a fall might cause the rope to cross between the tree and the rock. (If there is a pinch point)<\/span><\/li>\n<li><span><strong>Impact Force:<\/strong><\/span><span> Lower attachment points increase the amount of rope in the system, reducing impact force.<\/span><\/li>\n<li><span><strong>Tree Species and Root System:<\/strong><\/span><span> While species isn\u2019t critical, prioritize trees with thick trunks and strong, deep root systems. Be cautious if the tree is on thin, sandy soil or shallow bedrock.<\/span><\/li>\n<li><span><strong>Knots:<\/strong><\/span>\n<ul data-spread=\"false\">\n<li><span>Sebastiaan recommends avoiding the double figure-eight for this purpose, as it requires pre-measuring the rope length.<\/span><\/li>\n<li><span>For LRS anchors, he suggests avoiding bowlines or double figure-eights. These can interfere with friction knot tightening.<\/span><\/li>\n<li><span>His preferred knot: the clove hitch. It\u2019s simple, effective, and minimizes rope usage.<\/span><\/li>\n<\/ul>\n<\/li>\n<li><span><strong>Tree and Rope Protection:<\/strong><\/span><span> Always use protection to safeguard both the bark and the rope. Be mindful of potential slippage.<\/span><\/li>\n<\/ul>\n<h3 data-pm-slice=\"1 1 []\"><span>Acknowledgment:<\/span><\/h3>\n<p><span>Making the climbing community safer is a task we tackle as a group.
