F-C GEAR-BAG Fits on the bottom of your vise-shaft. It collects the "trimmings" as you tie (great when trimming deer-hair!) BUT LOOK: It pivots so that you can turn it upside down and empty it into a larger waste basket, without removing it from the vise shaft. It's only 3-1/4" deep by 6-1/4" x 6-1/4" square.
