Hoisin is often referred to as Chinese barbecue sauce, not because it has a similar flavor, but because it is used for a variety of purposes, similar to American barbecue sauce. Hoisin is also sometimes referred to as Peking sauce because it is used to create the thick glaze on the popular dish, Peking duck.
Balusters, the vertical guards that support the handrail, must be installed close enough that the space between them is no greater than 4 inches. Most city inspectors carry a 4-inch ball with them to test the spacing. Installed balusters should withstand 50 lbs. of pressure exerted over a 1-square-foot area.
For example, the balustrade of the 16th century Basilica St. Peters at the Vatican is truly Renaissance architecture. The baluster has come to be known as any vertical brace (often a decorative post) between an upper and lower horizontal railing. Staircases and porches often have balustrades or rails of balusters. The purposes of balusters are for safety, support, and beauty. Today's balusters are constructed of wood, stone, concrete, plaster, cast iron or other metal, glass, and plastics.
