Abstract: A modular laboratory bench includes a counter top and a floor mounted frame for supporting the counter top at a predetermined height above the floor. The basic frame comprises two rigid preassembled side support members which are interlocked by a front angle bar, a rear angle bar and a rear spacer bar at a distance which defines a predetermined moudlar spacing therebetween. A modular cabinet unit can be rolled into the modular spacing between the side support members and secured therein by a faceplate attached to the front angle bar.
