Hairdressing tongs have a pair of arms extending from handles. Each arm has a heating pad affixed thereto. The handles have opposed openings. A central element is positioned between the handles and fitted within the openings such that the central element is slidable toward the handles. The central element has guide openings. Springs are positioned in the guide openings for biasing apart the handles. The springs enable hand pressure to move the handles and arms together from a completely open position to a completely closed position and, in absence of the hand pressure, to maintain the handles and arms in relatively parallel configuration, biased against stops of the central element.

An exercise equipment frame, such as a power cage, is formed from uprights that comprise at least two sections that are telescopically interfit with one another. The sections have an interference fit between them when the telescopic interconnection is made that is tight enough to require the use of a tool that enables leverage greater than that achievable by the hand pressure of a user. The sections may be of substantially equal length to one another when forming the main uprights of the frame to allow packaging of the sections when disassembled in a carton of more regular dimensions. The sections may also be unequal length to allow coupling of a frame extension to the top of a completed power cage type frame.
