The Guardian Kernmantle rope horizontal lifeline (HLL)

The text of the notice:

If you have purchased a Guardian Kernmantle rope horizontal lifeline (HLL) from us before August, 2017, the manufacturer is asking that you stop use and inspect your lifeline. THIS IS NOT A PRODUCT RECALL, and there have not been any accidents or injuries related to this issue.

How to identify affected HLLs: Identify the HLL part #, which is located on the HLL label. If the HLL part # is included in this notice, immediately remove the product from service and inspect as specified by this notice.

If the shown “INSPECTED BY” label is affixed to the HLL tensioner, the product has been inspected by a Guardian representative, and can be returned to service and used as normal.

Part Numbers Affected:

  • #04638 (30’ Kernmantle Rope HLL)
  • #415TPEH-060 (60′ Kernmantle Rope HLL)
  • #04639 (60’ Kernmantle Rope HLL)
  • #04640 (100’ Kernmantle Rope HLL)
  • Any custom part that uses #04638, #04639, or #04640 as its base part.


STEP 1. Inspect Affected HLLs:

Distributors: Contact Preferred Safety Products regarding an on-site inspection by a PSP representative, or immediately return product to Preferred Safety Products for replacement as specified in Step 2.

End users: Inspect HLL tensioner to determine if rope is properly threaded, or contact PSP regarding an on-site inspection by a Preferred Safety Products representative.

End user inspection: With the tensioner nut facing you, and with the shock pack oriented to the right of the tensioner, ensure that the knotted (dead) end is positioned below the un-knotted (live) end. If dead end is positioned above live end, the rope is improperly threaded.

To confirm proper rope threading, pull on live end; the rope must remain locked. If the rope is improperly threaded, the device must be removed from service and returned to Preferred Safety Products as specified in Step 2. DO NOT ATTEMPT TO RE-THREAD ROPE.
