Ratchet-Fit™ leg strap adjustment for a secure fit; super-wide leg straps and a structured waist belt that spreads the load.
Marine-grade stainless steel ‘double back’ buckles with neoprene covers to prevent snagging.
User-replaceable leg-strap elastics, tool attachment points, a tripping-spike pocket accessible from both sides, and it integrates with the heavy-duty soft tool pack.

Diagram 1 shows closing/opening and tightening/loosening the buckles, shortening the waist belt to extra small and adjusting for comfort.
Put the harness on and test it (walking, sitting, standing and secured under tension) for a good fit and comfort.
A. Bowline. B. Halyard with shackle: attach the shackle back on the loop. No shackle: make a double half hitch with the tail of the halyard to secure the bowline.

Follow the orders of the climber.
Hoisting: keep the clutch closed during the hoist and while aloft; always tail the halyard round a winch.
Aloft: always keep the halyard under tension. Clutches are made for easy release – after hoisting and whenever someone is aloft, tie off the halyard on a winch in case the clutch is released by accident.
Lowering: support the halyard load on the winch while opening the clutch handle, and follow the instructions of the person aloft.
The harness is not designed to sustain a drop fall on a static rope. Icy or wet conditions increase the risk of accidents.

Scrap a harness showing wear that could affect its strength or function; ideally allocate it to a single user.
Check buckles and other fastenings regularly during use; check webbing and stitching before and after use, including the less accessible areas.
Every three months carry out a complete inspection (record sheet provided): fabric for cuts, tears, abrasion, heat or chemical damage; stitching for cut, torn, worn or loose threads; buckles for proper function.
Non-slip deck surfaces quickly abrade leg straps; they are protected with heavy-duty fabric. If the underlying structure of the leg straps shows through, replace the harness immediately.
Major falls: if full bodyweight has been dropped a distance and stopped, stop using the harness – internal damage may have reduced its strength.
Any modification or repair except by Spinlock's production facility is forbidden. Plan for rescue in case of difficulty aloft.

Hand wash and rinse in clean water, maximum 30° C; dry in a cool, ventilated, dark room.
Grease spots can be removed with trichlorethylene; webbing shrinks very slightly as it dries.
Carry and store it in its bag, in a clean dry place away from sunlight and extreme temperatures.
Disinfect when necessary with a disinfectant compatible with polyamide, polyester, polycarbonate and PVC, diluted in clean water at max 20 °C (as printed); soak for an hour, rinse in clean cold water, dry slowly away from direct heat.

Treat all chemicals (including petrol and battery acid), corrosives and solvents as harmful; after accidental contact, notify Spinlock stating the chemical.
Salt, sand, moisture and chemicals considerably accelerate wear.
Spinlock 2-year warranty against faults in materials or manufacture; excludes normal wear and tear, modifications, incorrect storage, accident, negligence and uses it was not designed for.
