Wooster RR013 Jumbo-Koter Sherlock Mini Pro 12" Roller Frame

Wooster RR013 Jumbo-Koter Sherlock Mini Pro 12" Roller Frame

The Wooster RR013 Jumbo-Koter Sherlock Mini Pro Roller Frame is a 12" mini roller frame built specifically for Wooster's Jumbo-Koter line of 4-1/2" roller covers. This frame gives painters a dedicated handle for mini roller work, letting you cut in, edge, or paint smaller and detailed areas with the same reliable grip and control expected from full-size Wooster frames. Sold individually as each, the RR013 is sized specifically to accept 4-1/2" Jumbo-Koter covers, making it a purpose-built companion tool for that cover line rather than a universal fit for every mini roller cover on the market. If you already run Jumbo-Koter covers on your larger frames, the Sherlock Mini Pro extends that same matched-system approach down to detail and trim work, so you are not improvising with a mismatched handle when the job calls for a smaller roller.
