Gra Lab Timer Model 300

Even in total darkness you can read the minutes and seconds on GraLab's Model 300 Darkroom Timer. It is used in industrial/commercial photo labs, graphic arts, printing, hobbyist darkrooms and is probably the most popular darkroom timer of all time. Set by seconds, minutes or a combination of the two, GraLab's exclusive dual-cam system gives you exact timing over long intervals. Two, three-wire receptacles can control an enlarger or printer and safelight with a combination time/focus switch. Rubber base pads, wall mounting keyholes and a recessed hand grip on the 7-1/2" x 7-1/2" x 2-1/2" polycarbonate case give you multiple placement choices. Model 300 withstands high impact, resists chemicals and moisture, and is electrically nonconductive.
