FOREWORD ® The new, smaller basketball backboard that was adopted by the National Basketball Committee of the United States and Canada during their annual 1940 meeting in Kansas City, as legal equipment, represents a combination of the results obtained from a large number of experimental tests made throughout the United States over a period of many months. The tests were promoted by a general realization among basketball authorities that the old 4'x6’ backboard had outlived its usefulness and was long overdue for revision in the light of today’s game. Tests were conducted by Rules Committee members, basketball coaches, and manufacturers working in co-operation with the Rules Committee. Substitution of the new, smaller backboard for the old 4’x6’ board presents several minor installation problems. For example, the majority of backstop installations are either overhead, suspended type or wall attached type. In both types, and in other special type installations, the supports are generally attached close to the ends of the 6’ wide backboard. A comparison of the old backboard with the new (see following pages) discloses the need of respacing existing supports to accommodate the smaller backboard. The above task does not present any problems that an efficient local mechanic cannot easily handle. High Schools and Universities having shop facilities will undoubtedly desire to undertake this work without seeking the services of an outside mechanic. This manual has been prepared as a service to all Medart customers and prospective customers, and outlines our suggestions for making the necessary changes in existing backstop structures.
