摘要： A working cap system suitable for supporting an extensive variety of construction materials and methods for manufacturing and using same. The working cap system can include an integrated working region with first and second support regions. The first support region can include a first support surface that is bounded by a pair of opposite first peripheral side surfaces; whereas, the second support region can be disposed within the first support surface and include a second support surface that is bounded by a pair of opposite second side surfaces. The first side surfaces, the first support surface, the second side surfaces and second support surface can define a central channel for receiving a selected work piece with a predetermined cross-section. Thereby, a wide variety of construction materials thereby can be supported by the working cap system.

摘要： A ladder apparatus has a first ladder section having a pair of side rails and a plurality of rungs extending between the side rails, a second ladder section hingedly connected to the first ladder section adjacent an upper end of the first ladder section, and a latch mechanism affixed to one of the ladder sections and engageable with the other of the first and second ladder sections. The second ladder section is movable between an extended position and a retracted position. The latch mechanism is adapted to secure the second ladder section in the retracted position. The second ladder section will extend in generally parallel relation to the first ladder section when in this retracted position. A ladder top is affixed to the upper end of the first ladder section and extends outwardly therefrom so as to have an end surface positioned away from the first ladder section.
