Life support
Saddles & climbing harnesses
The bridge, D-rings and stitching carry the climber. Inspect them at every tie-in and after every hard day.
Safety features explained
Replaceable floating bridge
The bridge is the one wear part designed to be swapped; it centers load and lets the climber move side to side.
Load-rated attachment points
D-rings and bridge attachment points are rated for life support; side D's and tool loops are positioning or gear-only.
Bar-tack stitching pattern
Bar tacks are the visual tell-tale on webbing — a single broken tack or discolored thread means the webbing has been loaded or abraded.
Daily inspection checklist
- 1Flex every webbing leg and strap in a U to expose cut fibers and broken threads.
- 2Inspect the bridge end-to-end for fuzz, glazing, cuts, and the stitching or knot at both ends.
- 3Check D-rings and metal hardware for wear grooves, sharp edges, bending and corrosion.
- 4Test buckles and quick-connects: they latch, hold, and release cleanly with no grit.
- 5Look at leg pads, batten and back pad for hidden abrasion and rot underneath.
- 6Check the ID label for model, date of manufacture and inspection log entries.
Out of service now
- Cut, melted or heavily abraded webbing in any load path.
- Broken, pulled or discolored stitching at a bar tack.
- Bridge worn beyond the manufacturer's wear indicator, or over its service life.
- Deformed, cracked or deeply grooved D-ring.
- Buckle that will not stay latched or is missing a part.
Operating best practices
- Dress the saddle to the body: D-rings at the hips, leg pads level, bridge free to run.
- Keep tools on tool loops only — never clip life support to a gear loop.
- Minimize static suspension time and plan rescue for suspension trauma.
- Store hung and dry; never stuff a wet saddle in a truck box.
Standards & compliance
- ANSI Z133: arborist saddles are inspected before each use and removed when defective.
- Follow manufacturer service life and mandatory bridge-replacement intervals.
- OSHA 1926.502 where the saddle is part of a fall-arrest system.
Summarised for field use. The current ANSI Z133 standard, OSHA rules and the manufacturer's manual are the controlling documents.
