The track quick clamps are designed to lock into BOSCH track-saw tracks to secure the tracks to the workpiece with a squeeze of a trigger. The ratcheting FSNKZW track quick clamps have metal fastener tabs that fit in the slots in the end of the tracks, providing fast locking. They provide push-button fast release. The tracks (sold separately) are part of the BOSCH track saw and track-guidance system, which allows precise end-to-end cuts and plunge cuts. They are very easy to work with. The track saw, along with the tracks, can be a more-easily transportable alternative to a table saw to a jobsite. The cuts are table-saw quality, with virtually No splinters.
