GraLab
Model 300 Darkroom Timer
Dimco-Gray Company

This classic American-made GraLab Model 300 darkroom timer is a staple of traditional film photography, manufactured by the Dimco-Gray Company in Dayton, Ohio. Designed for precision in the darkroom environment, this electromechanical timer features a large 60-minute luminous dial that remains visible under safelight conditions. The unit is equipped with two specialized outlets on the rear panel-one for an enlarger and one for a safelight-allowing for synchronized power control during the printing process.

• Dual-outlet design automatically switches off the safelight when the enlarger is activated
• High-visibility 6.5-inch luminous dial with 60-minute timing range and inner second markings
• Durable heavy-duty metal housing designed for professional laboratory and darkroom use

Condition: Significant cosmetic wear consistent with age and professional use. The exterior metal casing shows prominent surface oxidation and rust, particularly on the top and side panels. The front faceplate is dusty and features a circular opening at the upper right above the power markings. The power cord is attached and intact. The item is untested and is sold as-is.
