Description:
*These hollow full length 24/40 Standard Taper joint stoppers are closed at the bottom. They are interchangeable with standard taper joints of the same size.
*These hollow stoppers are light in weight, yet very strong to reduce chipping and breakage, thus minimizing replacement costs. A barrel-shaped head means it is easy to clean and even easier to rotate in or out. Grooves in the sides help prevent slippage.
*The flat top allows the stopper to stand on its head, which frees the user's hand and minimizes potential contamination.
