Installation is fast and easy with the portable MSRT9 Installation Tool. The MSRT9 clamps belt end and fastener strips in precise alignment while the rivets are driven. The Flexco MSRT9 multiple-rivet driving system uses pre-loaded guide blocks to hold 32 rivets in alignment over the rivet holes of four adjacent R9 fastener plates. The standard Flexco SR five-pronged drive rod is used to drive and set five rivets simultaneously, then turned 180 degrees to drive and set the remaining three rivets. The MSRT9 installs R9 fasteners only.
