Wahl lithium detailers black - model 8171L - blades

[Mcavoyd]

Hello all, please see attached photo. Just purchased these Wahl detailers and disassembled to zero gap blades.
Gave anyone else seen this type? I’ve looked for replacement blades online and have not seen any with this plastic piece attached. There is no way to adjust like the usual 5 star t wide blades. Any info would be great. Thanks
