The Norren Modular System is a completely new approach to instrument storage facilities. It is based on a standard-size cabinet, 48 1/2 wide x 28 deep x 41 1/2 high -- with a group of standard sized compartments which can be arranged in a wide variety of combinations. The result is 43 different cabinets that can be intermixed, double stacked or bolted together as one assembly to permit long range planning for the future expansion of storage facilities. Every Norren Cabinet is guaranteed to be free of defects in material and workmanship for a period of one year.
