Convert any Fretz® M-100 series stake to use as a full mushroom stake with the Fretz E-101 extender holder. The extender holder fits into the H-101 or VH-101 tool holders. Slide your M-100 series stake into the E-101 extender and you're ready to go! After using the stake, it can be a challenge to remove it safely and undamaged from the extender holder; to accomplish this, insert the E-100 removal wedge (included) into the extender beneath the stake end and tap the wedge. This will release the stake quickly and easily from the holder.
