Product Support Update
ISC REFLEX - Performance Investigation Update
On 19 June 2026, ISC issued an update regarding ongoing investigations into reports of performance fade and slippage affecting some REFLEX mechanical hitch devices.
Following analysis of user feedback, returned devices and product testing, ISC identified accelerated wear of the upper rope-engaging links as a common characteristic in devices exhibiting performance degradation.
ISC states that its investigations have found no evidence of manufacturing defects, component tolerance issues or assembly concerns. However, certain operating conditions may significantly increase wear rates, including repeated high-speed descents, extended descents, use without additional friction where appropriate and operation in dirty or abrasive environments.
Affected product: ISC REFLEX Mechanical Hitch Device.
Customer action: Users should regularly inspect their REFLEX device, monitor for reduced grabbing performance, unexpected slippage or signs of performance fade, and remove the device from service if concerns cannot be resolved through cleaning, maintenance or inspection.
ISC advises users not to rely solely on time in service when assessing device condition and to contact ISC directly if any performance concerns are identified.

Inspection Recommendation
Marlow Vesper Climbing Line - Vesper Splice
Marlow Ropes have issued a product inspection recommendation for Vesper tree climbing ropes up to and including April 2023.
The notice relates to a possible manufacturing defect affecting a small percentage of ropes, estimated by Marlow as 2%-3% of ropes. The Vesper splice includes a small lock-stitch designed to prevent the splice moving if manipulated by hand, such as when forcing a large karabiner into the eye.
Marlow state that the stitch does not contribute to the strength of the splice and that Vesper ropes pass EN 1891 requirements with or without the lock-stitch. However, customers are advised to inspect applicable ropes following the manufacturer guidance.
Affected products: Vesper tree climbing ropes up to and including April 2023.
Customer action: Inspect the splice and follow the Marlow inspection recommendation.

Product Recall
STIHL RMA 235.0 Battery Lawn Mower Recall
