TapeTech Corner Flushers can work as both a direct or indirect flusher. The Creaser Wheel Kit can be purchased separately to attach to any Corner Flusher to allow the joint tape to be pushed and creased at the same time the internal corner is being wiped down with the Corner Flusher. Roller Kits with wheels can also be purchased separately to help the Flushers glide down the wall effortlessly.
