Abstract

A device for securing a table saw accessory downstream of a saw blade. The device comprises a mount for securing the device to a table saw beneath a throat plate of table saw; a slide for receiving a stem carrying a table saw accessory; a releasable detent for capturing such stem and holding a table saw accessory in place; and an actuator for releasing the detent. The actuator is actuated from directly above and moveable downwardly vertically to release the detent. The device is particularly suited to quick change of saw splitter devices.
