Evaluation results: a single wrist restraint was returned, this product is sold in pairs.The foam cuff at the end with box stitch and white hook is torn.All labels are present and legible.No loose or broken threads found.Upon evaluation of the torn foam cuff, the tear appears to have originated at the box stitch that secures the webbing to the foam.The box stitch is intact and the foam sewn with the box stitch has torn suggesting excessive force was applied resulting in the failure.It does not appear there was any other failure in the foam as the other box stitch area of the foam is intact.During the sewing process, the stitch needle perforates the foam when creating the box stitch, thus weakening the foam and a possible start point for a tear or rip when excessive force is applied.In regards to the complaint about the strap slipping, it is possible that the customer is not following step 5 of the instructions for use by twisting the strap 180 degrees during application.The instructions also advise the user to tie an overhand knot with the excess strap directly below the quick-release buckle to limit unwanted movement.This customer is new to posey soft limb holders and it is possible that on-site training, while typically performed for new customers, did not occur due to restrictions related to the covid-19 pandemic.Therefore, the apparent likely cause of the failure is use error or failure to follow instructions for application of the device.At this time, there is no evidence that a manufacturing defect contributed to the reported failure.All complaints are trended and reviewed by management on a monthly basis.As a part of the monthly review, any excursion above the control limits for this failure mode will be assessed, documented and acted upon as warranted.The instructions for use (ifu) were reviewed and found to provide adequate instructions and warnings for safe and effective use of the device.No corrective or preventative actions are necessary at this time.Manufacturer reference file# (b)(4).
