Exclusive POSAlinc 360 technology swings away the knee adductor in any direction while it stays attached to the chair, allowing compatibility with most chair configurations. The adductor locks back into its original position when swung back into place. POSAlinc 360 is durable, with no play in the swing-away mechanism. The adductor is available in standard (7″) and extended (10″) post sizes— the latter suggested for power chairs or high cushions.
