ProMediaGear PASL1 Strap Loop Overview The ProMediaGear PASL1 Strap Loop is made for ProMediaGear Bracket Plates. It fits on the groove of a PMG L-Bracket or any bracket plate. The PASL1 Strap Loop, once attached, fits most hand straps and other carrying straps. This Strap Loop works with bracket plates starting with the letters "PB" such as the Nikon Z9 PBNZ9 bracket plate. Other ProMediaGear Arca-plates that do not start with the letters "PB" are not compatible with the PASL1.
