Heavy-duty toothbrush-style scratch brush with 0.006" Stainless Steel Wire and a Plywood Handle in a curved design for knuckle protection. This large scrubber brush is ideal for cleaning wider areas. The stainless steel bristle, hand-laced with stainless steel wire, remains secure even in wet environments if the wooden handle expands or contracts. Hand-laced brushes are the premium brushes in the industry. Each fill tuft is tied into position by hand, resulting in a superior quality brush with maximum fiber retention. Greater bristle density than staple set brushes. This useful brush has a 4 x 11 row configuration, with a 3/4" trim, and a brush face of 2-5/8" x 7/8". Handle length is 8-1/2" x 1".
