Summary: Sharon J Lilly, Alex K Julius avail Arborist News Aug 2025 Tree Climbers' Guide: Climbing Equipment caring, inspecting, retiring tree-climbing equipment.
"God talks to human beings through many vectors: through each other, through organized religion, through the great books of those religions, through wise people, through art and music and literature and poetry, but nowhere with such detail and grace and color and joy as through creation. When we destroy a species, when we destroy a special place, we're diminishing our capacity to sense the divine, understand who God is and what our own potential is." Robert Francis Kennedy Jr., April 19, 2023, Boston Park Plaza Hotel, Back Bay, Boston, Massachusetts.
“And there’s many people out there who want us to move to the next planet already and I’m like, hang on, let’s not give up on this planet yet," William, Prince of Wales, July 31, 2023, Sorted Food food truck, London, England, United Kingdom.

Sharon J Lilly and Alex K Julius avail Arborist News Aug 2025 Tree Climbers' Guide: Climbing Equipment caring, inspecting, retiring tree-climbing equipment even as they articulate buying options, inspection protocols and use.
Breaking in tree-climbing equipment and gear perhaps begins most basically with equipment-and-gear experts at such International Society of Arboriculture events as the official ISA tree-climbing championships. Equipment and gear competencies come from choosing, purchasing, using according to applicable standards, good working-order maintenance, manufacturers' recommendations and operational compatibility with other tree-climbing system elements. Climbing-style helmet, hard-hat inspections deem dangerous adhesive, stickered surfaces; bubbled, cracked, crazed, warped shells; cracked, missing-component, shell-attached padding; cut, damaged suspension; dysfunctional chin-strap, cinching; expired dates.
Safety-glasses, hearing-, leg-protection inspections respectively entail evidencing cracks, scratches; irregular-replaced disposable earplugs; excessive-wear, misfitting, missing-foamed earmuffs; burned, compromised, nicked chain-saw chaps-over-pants ensemble or chain-saw protective pants.
Climbing-harness inspections finger burned/corroded/cracked/disfigured metal; cracked/crazed plastic; cut/discolored/pulled/unraveling textile; D-ring, dual-/floating-/rope-bridge, fixed/sliding Ds, O-ring suspension attachments; dysfunctional buckles; enlarged-hole webbing; expired dates; overworn load-bearing rivets, stitching.

| Authors Sharon J. Lilly and Alex K. Julius list hitch cords and split-tails in the "Fall Protection and Work Positioning" section of their article on "Tree Climbers' Guide: Climbing Equipment" in the August 2025 issue of ISA International Society of Arboriculture's Arborist News. A hitch cord, which is a smaller-diameter cordage, ties a type of knot, the friction hitch, with a short loop. A split-tail rope ties another type of knot, the climbing hitch, onto the climbing line. "For many climbers, a split-tail and hitch was where it started," artwork by tree care industry illustrator, climbing arborist and Tree Climbers' Guide illustrator Bryan Kotwica.: Sherrilltree, via Facebook March 18, 2026 |
Climbing-harness inspections finger burned/corroded/cracked/disfigured metal; cracked/crazed plastic; cut/discolored/pulled/unraveling textile; D-ring, dual-/floating-/rope-bridge, fixed/sliding Ds, O-ring suspension attachments; dysfunctional buckles; enlarged-hole webbing; expired dates; overworn load-bearing rivets, stitching.
Connecting-link rope-snaps, quick-links inspections respectively gage corroded/cracked/flaked/rusted metal, deformed body, dysfunctional operation/closure, enlarged attachment points; corroded/cracked/flaked/rusted metal, deformed body, dysfunctional closing/tightening, and, like connecting-link carabiners, grooves. Major axis-loaded carabiners-, major axis-loaded, self-closing/self-double locking triple-action tree-climbing carabiners-inspecting heed corroded/cracked/flaked/rusted/worn metal; deformed body, gate, major axis, spine; delayed/misaligned/sticking unlocked/half-opened/open gate; dysfunctional locked-position closure; grooves. Climbing-ropes inspections; carabinered, eye-spliced, rope-snapped climber-securing work-positioning lanyards-inspecting respectively investigate abraded-/cut-/deformed-/puffed-fiber diameter/discoloration/glazing, alternate-ended taping-/whipping-sealed ends, damaged/missing whip-stitched eye-splices; abraded/diameter-changed/discolored/glazed/nicked/overworn lengths, dysfunctional adjustment-mechanisms/carabiners/snaps, expired dates, protruding wires.
SJ Lilly and AK Julius journey Arborist News Aug 2025 through Tree Climbers' Guide: Climbing Equipment even as tree climbers jubilate hitch-cord, Prusik-loop, split-tail rope tools.
Climbing hitch-tying, separate-, short-cordaged split-tails and friction hitch-tying, small-diameter hitch-cords inspections respectively know dangerous abraded/cut/diameter-changed/discolored/glazed/puffed fibers, changed/protective-plastic-missing stitched eyes, damaged/missing stitch-covered/whip-stitched eye-spliced sewn lines, expired dates.

The Prusik (Karl Prusik, Tue., May 19, 1896-Mon., May 8, 1961) loop, as splice-, double-fisherman's bend-formed cordaged-rope tool, logs great success in securing another secured-footlocking line.
