MTN TIP
Fit first, then features. Try your harness with the layers and PPE you actually wear, confirm sternal/dorsal/lateral attachment placement, and practice donning/adjustment until it’s repeatable. Pair with the right lanyard or SRL and follow the inspection schedule. Explore our Height Safety hub for compatible gear and checklists.
PRO TIPS WHEN CHOOSING A HARNESS
- Sizing & fit: Correct sizing keeps attachment points where they belong and maintains comfort over long days.
- Task profile: Rope access & rescue typically favor more gear capacity; daily fall arrest often prioritizes quick, consistent donning.
- Attachment points: Match to your system (sternal/dorsal for fall arrest; lateral for positioning).
- Inspection: Use indicators and track service life; retire any harness exposed to a significant fall.
- Accessories: Add CARITOOL holders and TOOLBAG pouches to keep hands free.
