How to inspect a TRUBLUE Auto Belay

Daily Inspection 

The daily webbing inspection must include at least a visual inspection sufficient to evaluate the wear and integrity of the device’s webbing. Please see “Webbing Wear” below for a detailed description of when a webbing should be taken out of service. The inspection may be performed from the ground if the webbing can be adequately inspected.

Weekly Inspection

The TRUBLUE Auto Belay must be inspected weekly for correct operation and overall condition. The weekly inspection may be carried with the unit in place or removed to a sturdy work table.


Ensure adequate lighting and unrestricted access is available to permit a thorough inspection of all areas of the Auto Belay. This inspection should be completed either with the Auto Belay dismounted or by climbing to the location of the Auto Belay and anchoring in, so you may visually inspect the unit and the entire length of webbing.


1. Clean any dust, dirt or contamination off the casing and fittings with a clean cloth.
*DO NOT USE SOLVENTS OR ABRASIVES Clean with a cloth only. Do not use any cleaners, solvents or abrasives on any part of the Auto Belay or its associated equipment.

2. Visually inspect the casing, mounting holes and plastic covers for wear, impact damage, cracking, deformation and corrosion. Replace any damaged items or remove Auto Belay from service.

3. Check all safety labels are in place and in good condition.

4. Check date on Certification Label is current.

5. Inspect the condition of the carabiner, checking for:
  • Wear and damage.
  • Correct operation of the locking mechanism.
  • Smooth operation of the carabiner swivel. 
If the carabiner gate or swivel does not automatically lock or rotate, lubricate per the carabiner manufacturer’s recommendations, which include a dry, wax-based or PTFE-based lubricant, until fully operational. If full functionality cannot be restored, replace the entire webbing assembly.

6. Slowly pull out the entire length of webbing from the unit. As webbing is withdrawn, inspect for:
  • Damage, cuts or abrasion to stitching.
  • Cutting, wear and abrasion to the surface of webbing.
  • Discoloration, fading or chalking of the surface.
  • Heat and friction damage such as hard or shiny areas.
  • Contamination from dirt or chemicals.
  • Twisting or knotting.
Replace webbing if any signs of wear or damage are present.

7. Allow the webbing to slowly retract into the casing – checking the retraction action is strong and smooth.

8. Complete and file ‘Weekly Inspection Log’ documentation.

9. Return Auto Belay device to service.
