Adapter for Pinch Tab Top Button Arm (PTTB) – Used on BMW Series 5 and 6 for limited years. It first appears the same as the standard pinch, but the blade is connected in a totally different manner.
Adapter for Pinch Tab Side Lock Arm (PTSL) – 15mm wide saddle. Two tabs are pinched together and the blade swivels off the front of the arm.
