Low Profile Work Stop, T-Slot Track
Used in a 1/4-20 T-slot track, it can be secured at any point of the track. 1-3/16" in diameter overall.
With a projection of only 1/4", this low-profile stop allows thin materials to be worked without obstruction. The brass head pivots to accommodate round or irregularly shaped workpieces; its two flat faces are canted inward by 2° to help hold wood securely.
