The Rockler Shutter Building System produces shutters with louvers in three industry-standard sizes with configurations that either open and close or are fixed. The system allows shops to build custom wood window shutters without having to add fabrication or assembly equipment to their tool inventory, says the company. The company provides a free shutter design application at Rockler.com/shutter that provides a complete step-by-step plan for building each shutter. The system leverages specialized drilling jigs that allow users to precisely space and align louvers using a cordless drill. Basswood for the shutter frames and ready-to-cut basswood louvers can be purchased, as well as hardware to attach the louvers and control arm hardware to open and close the shutters. The Rockler Shutter Jig Kit is available in three louver widths – 1-1/4", 2-1/2" and 3-1/2" and designed for use by professional woodworkers as well as hobbyists.
