The CRL Notching Cut-Out Template is a labor saving device used for fabricating those "impossible" notches in glass up to 3/8" (10 mm) thick. Any size three-sided notch between 3/4" x 7/8" (19 x 22 mm) minimum and 13-1/8" x 6" (333 x 152 mm) maximum can be made easily using this template. A 9/32" (7 mm) corner radius is produced while using our TP2800 Glass Cutter. The template is constructed from a synthetic resin and the finest hardware. It is secured to the glass by three built-in suction cups. There are also two adjustable depth stops that double as "runoff strips" for your cutting wheel. Ideal for fabrication of window pass-thrus, shower door hinge notches, and just about any place a cut-out is needed. The TP181 is sold each. (Minimum and maximum dimensions are approximate depending on the style of cutter being used.)
