TL;DR: ACCT International posted the ISC REFLEX support update on June 19, 2026, warning that accelerated upper-link wear can cause slipping and early retirement.
What ACCT posted on June 19, 2026
According to Technical Bulletins - ACCT International, the newest entry on that archive page is titled ISC Product Support Update REFLEX and carries a posting date of 06/19/2026. The same listing describes the entry as an update to a notice originally published in April 2026 from ISC Solutions in Metal. The page groups the entry under Technical Bulletins alongside other safety communications for challenge-course, zip-line, climbing, and work-at-height equipment. For outdoor users and program operators, that placement signals that the REFLEX matter should be treated as an operational safety check, not as general product news. The ACCT listing provides only a short preview and directs readers to continue reading the full manufacturer message.
Who issued the REFLEX update
According to ISC Product Support Update_REFLEX, the full message is dated June 19th 2026 and is addressed to all REFLEX climbers. The author is identified as Carly Jones, Product Manager, writing for International Safety Components Ltd. in Bangor, Gwynedd, United Kingdom. The company address is listed as Unit 1, Plot 2, Llandygai Industrial Estate, Bangor, Gwynedd LL57 4YH, with telephone +44 (0) 1248 363 110. The message thanks users for support of the REFLEX and for feedback supplied after the earlier communication. It states that user-shared information helped the company understand device behavior across climbing styles, rope conditions, and environments.
What ISC investigated after the April notice
The ISC message states that following its earlier letter, the company continued to examine reports of performance fade and slippage. The work included review of user feedback, evaluation of returned devices, and testing and analysis. The company notes that rope condition, device condition, contamination, and general operating conditions affect performance of any mechanical hitch device. It reports that some reported concerns could be resolved by correcting one or more of those factors. Separately, it states that a small number of devices kept showing performance fade even after rope and device conditions were appropriately managed. Those units were sent back to ISC for detailed evaluation.
The wear finding on the upper links
The detailed evaluation identified visible wear on the upper links, described as critical components responsible for engaging the rope and arresting movement. The common characteristic among returned units was accelerated wear of those rope-engaging components. The investigation found no evidence to date of manufacturing defects, component tolerance issues, or assembly concerns. The observed wear appears to be the common factor associated with performance fade reported by affected users. Testing and analysis indicate that certain operating conditions can significantly increase wear rates. Listed conditions include extended descents, repeated high-speed descents, use without additional friction where appropriate, and operation in dirty or abrasive environments. In some cases, the observed wear is resulting in reduced device performance and early retirement of the individual device.
What retirement and inspection mean now for owners
The ISC message states that some devices may require retirement earlier than time-in-service alone would suggest. It emphasizes regular inspection and monitoring of performance as particularly important. Climbers should pay close attention to noticeable changes in device behavior, including reduced grabbing performance, increased tendency to slip, or other signs of performance fade. Users should not rely solely on time in service when evaluating condition. If performance degradation cannot be resolved through cleaning, inspection, maintenance, or addressing rope and environmental conditions, the device should be removed from service and ISC should be contacted directly. The message adds that, as with all life-support equipment, users should not continue using equipment if they have concerns regarding condition or performance.
ISC commitment and next steps described as ongoing
The company states that it understands the REFLEX represents a significant investment for many climbers. It says it is actively working with users who experienced these issues and is committed to ensuring affected customers are appropriately supported while investigation continues and long-term solutions are evaluated. The investigation remains ongoing. Findings to date are described as providing valuable insight into performance characteristics of the REFLEX in demanding real-world applications. The company states it is currently evaluating several opportunities to address the situation and will continue providing updates as work progresses. Users experiencing performance fade, unexpected slippage, or other concerns about condition or performance are instructed to remove the device from service and contact ISC directly through ISC REFLEX Support. The company states it is committed to investigating every reported case and supporting users through the process.
Other active bulletins listed on the same ACCT page
The same ACCT Technical Bulletins listing shows an Edelrid general safety notice for OHM II, OHMEGA, and FUSE products, posted 05/6/2026. The preview states that a screw installed incorrectly was discovered. Program managers who use assisted-braking devices should open that separate bulletin for product-specific instructions. Another entry calls for visual inspection of SIMBA CLIMBING/SIMBA PARK and SWAN EASYFIT STEEL/SWAN EASYFIT STAINLESS harnesses, posted 03/2/2026. That preview states the action follows discovery, on one harness, of a missing rivet on the FAST LT PIN-LOCK buckle on the back of the harness. The listing also shows a RECALL FOR INSPECTION for the C.A.M.P. NIMBUS LOCK CARABINER, posted 07/24/2025. Its preview notes an update dated 2025-08-28 stating that CPSC filing has occurred and describing a voluntary product action.
CLUTCH, SAFEROLLER, and harness recalls operators should keep filed
The archive further lists an INSPECTION NOTICE issued by CMC/Harken on CLUTCH, posted 05/1/2025. The preview limits the scope to CLUTCH units manufactured November 19, 2024 through April 10, 2025. It identifies 11 mm and 13 mm CLUTCH units with product numbers 335011-01 and 335013-01 and serial numbers 2024 324 - 001 through 2025 100 - 999. A KANOPEO Bifurcation SAFEROLLER bulletin, posted 07/8/2025, is summarized with the phrase concerning SAFEROLLER and bifurcations. The quoted assessment states no immediate danger, but requires special attention or monitoring with potential long-term risk. A separate KANOPEO notice, posted 03/26/2025, covers CAREBINER 2 - 2025 V6 or later and SAFEROLLER PPE TROLLEY TYP 3 2025 V3.5 or later. Its preview states that KANOPEO has been ISO 9001:2015 certified since 06.03.2019 and that certification improved development, production, control, information, and monitoring processes.
The same page carries an IMPORTANT VOLUNTARY RECALL for SWAN EASYFIT STEEL and STAINLESS harnesses. The preview attributes the action to Petzl, cites a defect in the FAST LT buckle that could lead to a fatal fall, and instructs users to immediately stop using affected harnesses. A related recall covers certain batches of the European Version of NEWTON harnesses manufactured in 2022, plus NEWTON FAST and NEWTON EASYFIT, citing a nonconforming batch of FAST LT buckles that could lead to a fatal fall, with the same stop-use instruction. Older entries include a TRUBLUE iQ safety alert identified as Bulletin Number SA 0005, a voluntary recall of GYM, PANDION, and PANJI harnesses following a May 14, 2024 safety alert communication and work with the United States Consumer Product Safety Commission and Health Canada, and a TRUBLUESpeed safety alert identified as Bulletin Number SA 0004.
How to use this bulletin set in the field
Treat the June 19, 2026 REFLEX update as the current operating instruction for that device, while retaining the April 2026 notice for history. Log REFLEX serial numbers, inspection dates, cleaning actions, rope pairings, and any change in grab or slip behavior. Separate devices that recover after cleaning and rope-condition correction from devices that continue to fade, because only the second group is described as requiring removal from service and direct contact with ISC. Keep the Edelrid, Petzl harness, C.A.M.P., CMC/Harken, KANOPEO, and TRUBLUE bulletins in the same compliance file, since mixed fleets often contain several affected product families. Check the original ACCT Technical Bulletins page and linked manufacturer documents before training, seasonal opening, or purchase of used gear.
