Inspection, points to verify

Before each use 

- Harness

Check the webbing at the attachment 

points, at the adjustment buckles and at 

the safety stitching. 

Look for cuts in the webbing, wear 

and damage due to use, to heat, and 

to contact with chemical products, 

etc. Be particularly careful to check for 

cut threads. 

Verify that the DoubleBack and FAST 

buckles operate properly.

- TOP 

Directional connector

Make sure the body, gate, gate hinge and 

locking sleeve are free of any cracks, 

deformation, corrosion, etc. Open 

the gate and verify that it closes itself 

automatically when released. Verify that 

the locking sleeve operates properly. The 

Keylock slot (gate) must not be blocked 

by any foreign matter (dirt, pebble, etc.).

- TOP CROLL 

Directional maillon rapide

Before each use, check the body. 

Verify that the locking nut is screwed 

on completely (no threads visible) and 

tightened with a torque of 3 Nm.

CROLL ventral rope clamp

Before each use, check the condition of 

the body, the attachment hole, the cam 

and the safety catch (cracks, scoring, 

deformation, wear, corrosion), the cam 

springs and axle. Make sure the teeth 

are not worn out. Attention, do not 

use a rope clamp that has missing or 

worn-out teeth.
