Sometimes referred to as "five-sided," or "tri-level," this wash brush is made with the block recessed so the soft bristles extend on the sides, eliminating the chance that the block will touch the paint. The green polyester bristles are flagged and soft on the ends, and also soft throughout. The green nylon is the softest bristle of all the five-sided brushes, and the most popular.
This fountain/flow-thru block accepts all standard acme threaded handles.
Bristles are 2.5" in length, Block is 8" in length.
