Norbert's new infinitely connectible sectional beams are fun to use, quickly configurable and easy to store. Each 4' long x 4" high practice beam is covered with beam suede and filled with solid (but very light weight) crosslink foam. 4" wide top surface tapers to a 6" wide base. Beams connect end-to-end securely with permanently attached velcro fastener. Excellent for gym or home use.
